We look at the division of 681559 by 57 
The aim is to understand the frequency of 57 in 681559.

Moving on to step 1:
57 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 57

Step 2:
57 goes into 68 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 57 from 68 leaves us with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 57

Going ahead to step 3:
111 divided by 57 is 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 57 from 111 and we're left with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 57

Moving on to step 4:
If we divide 545 by 57, we get 9 and a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we take 513 away from 545, we end up with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 57

Going ahead to step 5:
57 can be fit into 325 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 1195.0
If we take 285 away from 325, we end up with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 57

Moving on to step 6:
57 can be fit into 409 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 11957.0
Deduct 399 from 409 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 57, we get 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 11957.1
The remainder is 43 after subtracting 57 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
430 divided by 57 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11957.17
If we take 399 away from 430, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
If we divide 310 by 57, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11957.175
If we subtract 285 from 310, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
57 goes into 250 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 11957.1754
Subtract 228 from 250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
The number 57 fits into 220 3 times, leaving a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 11957.17543
The remainder is 49 after subtracting 171 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
57 goes into 490 8 times with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 11957.175438
If we take 456 away from 490, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
When dividing 340 by 57, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 11957.1754385
The remainder is 55 after subtracting 285 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
If we divide 550 by 57, we get 9 and a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 11957.17543859
Deduct 513 from 550 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 11957.17543859 with a remainder of 3.7e-08.
