402552 divided by 57 
The aim is to understand the frequency of 57 in 402552.

On to step 1:
4 divided by 57 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 57

Advancing to step 2:
40 divided by 57 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 57

On to step 3:
The number 57 fits into 402 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 399 from 402 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 57

Going ahead to step 4:
The number 57 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 57

Going ahead to step 5:
355 divided by 57 is 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 706.0
If we take 342 away from 355, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 57

Step 6:
57 can be fit into 132 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 7062.0
If we subtract 114 from 132, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
57 can be fit into 180 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 7062.3
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
If we divide 90 by 57, we get 1 and a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 7062.31
If we take 57 away from 90, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
When dividing 330 by 57, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 7062.315
If we subtract 285 from 330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
When dividing 450 by 57, we get 7 with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 7062.3157
Deduct 399 from 450 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
The number 57 fits into 510 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 7062.31578
If we take 456 away from 510, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
57 goes into 540 9 times with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 7062.315789
If we take 513 away from 540, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
57 goes into 270 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 7062.3157894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
If we divide 420 by 57, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 7062.31578947
If we subtract 399 from 420, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 7062.31578947, and the remainder is 2.1e-08.
