We're dividing 42430566 by 454 
The aim is to understand the frequency of 454 in 42430566.

Let's proceed to step 1:
If we divide 4 by 454, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 454

Let's proceed to step 2:
454 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 454

Advancing to step 3:
454 can be fit into 424 0 times, resulting in a remainder of 424.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 424 and we're left with 424.
Bring next digit (3) of the dividend behind the 424 and repeat the process: 4243 / 454

Advancing to step 4:
454 can be fit into 4243 9 times, resulting in a remainder of 157.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 157 after subtracting 4086 from 4243.
Grab the next digit (0) from the dividend, add it to 157, then carry on: 1570 / 454

On to step 5:
454 can be fit into 1570 3 times, resulting in a remainder of 208.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
The remainder is 208 after subtracting 1362 from 1570.
Bring next digit (5) of the dividend behind the 208 and repeat the process: 2085 / 454

Advancing to step 6:
454 can be fit into 2085 4 times, resulting in a remainder of 269.
The number 4 becomes the next digit in our result. 
Result so far: 934.0
Deduct 1816 from 2085 and we're left with 269.
Bring next digit (6) of the dividend behind the 269 and repeat the process: 2696 / 454

Moving on to step 7:
When dividing 2696 by 454, we get 5 with a remainder of 426.
Write down 5 as next digit of the result. 
Result so far: 9345.0
If we subtract 2270 from 2696, we get 426.
Append the next digit (6) from the dividend to 426 and continue with: 4266 / 454

Moving on to step 8:
454 goes into 4266 9 times with a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 93459.0
If we take 4086 away from 4266, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
The number 454 fits into 1800 3 times, leaving a remainder of 438.
Use 3 as the next digit of our solution. 
Result so far: 93459.3
Subtracting 1362 from 1800 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 10:
454 can be fit into 4380 9 times, resulting in a remainder of 294.
The next digit of our result is 9. 
Result so far: 93459.39
Subtracting 4086 from 4380 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 11:
The number 454 fits into 2940 6 times, leaving a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 93459.396
The remainder is 216 after subtracting 2724 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 12:
The number 454 fits into 2160 4 times, leaving a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 93459.3964
The remainder is 344 after subtracting 1816 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 13:
When dividing 3440 by 454, we get 7 with a remainder of 262.
Put 7 as the next digit of the answer. 
Result so far: 93459.39647
Subtract 3178 from 3440 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 14:
454 can be fit into 2620 5 times, resulting in a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 93459.396475
Subtract 2270 from 2620 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 15:
When dividing 3500 by 454, we get 7 with a remainder of 322.
The number 7 becomes the next digit in our result. 
Result so far: 93459.3964757
If we take 3178 away from 3500, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 16:
If we divide 3220 by 454, we get 7 and a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 93459.39647577
Deduct 3178 from 3220 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 93459.39647577 and a remainder of 4.2e-08.
