We look at the division of 61983 by 57 
The aim is to understand the frequency of 57 in 61983.

On to step 1:
6 divided by 57 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 57

Step 2:
61 divided by 57 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 57 away from 61, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 57

Step 3:
49 divided by 57 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 49 and we're left with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 57

Advancing to step 4:
498 divided by 57 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 456 away from 498, we end up with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 57

Step 5:
57 can be fit into 423 7 times, resulting in a remainder of 24.
The next digit of our result is 7. 
Result so far: 1087.0
Deduct 399 from 423 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 6:
If we divide 240 by 57, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 1087.4
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
When dividing 120 by 57, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 1087.42
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 57, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1087.421
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 57, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1087.421
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 57, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1087.42105
Subtract 285 from 300 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
57 can be fit into 150 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 1087.421052
If we take 114 away from 150, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 57, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 1087.4210526
Deduct 342 from 360 and we're left with 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 13:
180 divided by 57 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 1087.42105263
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 1087.42105263, with a leftover of 9e-09.
