We look at the division of 77868246 by 454 
The aim is to understand the frequency of 454 in 77868246.

On to step 1:
454 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 454

Step 2:
When dividing 77 by 454, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 454

On to step 3:
454 can be fit into 778 1 times, resulting in a remainder of 324.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 454 from 778 and we're left with 324.
Take the next digit (6) from the dividend and append it to 324, then repeat: 3246 / 454

Moving on to step 4:
When dividing 3246 by 454, we get 7 with a remainder of 68.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 3178 from 3246 and we're left with 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 454

Going ahead to step 5:
688 divided by 454 is 1 with a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtracting 454 from 688 leaves us with 234.
Fetch the next digit (2) from the dividend, attach it to 234 and continue: 2342 / 454

Moving on to step 6:
The number 454 fits into 2342 5 times, leaving a remainder of 72.
Record the quotient 5 as the next digit in the result. 
Result so far: 1715.0
Subtracting 2270 from 2342 leaves us with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 454

On to step 7:
724 divided by 454 is 1 with a remainder of 270.
Put 1 as the next digit of the answer. 
Result so far: 17151.0
If we take 454 away from 724, we end up with 270.
Append the next digit (6) from the dividend to 270 and continue with: 2706 / 454

Going ahead to step 8:
The number 454 fits into 2706 5 times, leaving a remainder of 436.
Use 5 as the next digit of our solution. 
Result so far: 171515.0
If we subtract 2270 from 2706, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 9:
If we divide 4360 by 454, we get 9 and a remainder of 274.
Write down 9 as next digit of the result. 
Result so far: 171515.9
The remainder is 274 after subtracting 4086 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 10:
If we divide 2740 by 454, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 171515.96
If we take 2724 away from 2740, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 454, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 171515.96
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
If we divide 1600 by 454, we get 3 and a remainder of 238.
The next digit of our result is 3. 
Result so far: 171515.9603
If we take 1362 away from 1600, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 13:
2380 divided by 454 is 5 with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 171515.96035
If we subtract 2270 from 2380, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 14:
The number 454 fits into 1100 2 times, leaving a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 171515.960352
Deduct 908 from 1100 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 15:
When dividing 1920 by 454, we get 4 with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 171515.9603524
The remainder is 104 after subtracting 1816 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 16:
If we divide 1040 by 454, we get 2 and a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 171515.96035242
Deduct 908 from 1040 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 171515.96035242, with a leftover of 1.32e-07.
