We're dividing 65412420 by 457 
The aim is to understand the frequency of 457 in 65412420.

Going ahead to step 1:
The number 457 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 457

Advancing to step 2:
When dividing 65 by 457, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 457

Going ahead to step 3:
457 goes into 654 1 times with a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 457 from 654 leaves us with 197.
Take the next digit (1) from the dividend and append it to 197, then repeat: 1971 / 457

Let's proceed to step 4:
When dividing 1971 by 457, we get 4 with a remainder of 143.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 1828 from 1971, we get 143.
Bring next digit (2) of the dividend behind the 143 and repeat the process: 1432 / 457

Advancing to step 5:
The number 457 fits into 1432 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 143.0
Deduct 1371 from 1432 and we're left with 61.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 457

Going ahead to step 6:
457 can be fit into 614 1 times, resulting in a remainder of 157.
The number 1 becomes the next digit in our result. 
Result so far: 1431.0
The remainder is 157 after subtracting 457 from 614.
Bring next digit (2) of the dividend behind the 157 and repeat the process: 1572 / 457

On to step 7:
The number 457 fits into 1572 3 times, leaving a remainder of 201.
The next digit of our result is 3. 
Result so far: 14313.0
If we take 1371 away from 1572, we end up with 201.
Grab the next digit (0) from the dividend, add it to 201, then carry on: 2010 / 457

Let's proceed to step 8:
457 can be fit into 2010 4 times, resulting in a remainder of 182.
The number 4 becomes the next digit in our result. 
Result so far: 143134.0
The remainder is 182 after subtracting 1828 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 9:
457 goes into 1820 3 times with a remainder of 449.
The next digit of our result is 3. 
Result so far: 143134.3
If we take 1371 away from 1820, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 10:
4490 divided by 457 is 9 with a remainder of 377.
Write down 9 as next digit of the result. 
Result so far: 143134.39
If we take 4113 away from 4490, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Step 11:
If we divide 3770 by 457, we get 8 and a remainder of 114.
Write down 8 as next digit of the result. 
Result so far: 143134.398
If we subtract 3656 from 3770, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 12:
457 goes into 1140 2 times with a remainder of 226.
Write down 2 as next digit of the result. 
Result so far: 143134.3982
Subtracting 914 from 1140 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 13:
2260 divided by 457 is 4 with a remainder of 432.
The number 4 becomes the next digit in our result. 
Result so far: 143134.39824
Subtract 1828 from 2260 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 14:
When dividing 4320 by 457, we get 9 with a remainder of 207.
Use 9 as the next digit of our solution. 
Result so far: 143134.398249
The remainder is 207 after subtracting 4113 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 15:
2070 divided by 457 is 4 with a remainder of 242.
Put 4 as the next digit of the answer. 
Result so far: 143134.3982494
If we subtract 1828 from 2070, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 16:
457 goes into 2420 5 times with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 143134.39824945
Subtract 2285 from 2420 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

After the division, we end up with 143134.39824945 and a remainder of 1.35e-07.
