We're dividing 665642 by 57 
The aim is to understand the frequency of 57 in 665642.

Moving on to step 1:
If we divide 6 by 57, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 57

Advancing to step 2:
The number 57 fits into 66 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 57 from 66 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 57

Advancing to step 3:
When dividing 95 by 57, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 57 from 95 to get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 57

Going ahead to step 4:
The number 57 fits into 386 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtracting 342 from 386 leaves us with 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 57

Advancing to step 5:
57 goes into 444 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 1167.0
Deduct 399 from 444 and we're left with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 57

On to step 6:
The number 57 fits into 452 7 times, leaving a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 11677.0
Deduct 399 from 452 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
The number 57 fits into 530 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 11677.9
Deduct 513 from 530 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
57 can be fit into 170 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 11677.92
If we subtract 114 from 170, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
57 goes into 560 9 times with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 11677.929
Deduct 513 from 560 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
470 divided by 57 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 11677.9298
If we subtract 456 from 470, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
When dividing 140 by 57, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 11677.92982
Subtracting 114 from 140 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
If we divide 260 by 57, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 11677.929824
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
When dividing 320 by 57, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 11677.9298245
The remainder is 35 after subtracting 285 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
When dividing 350 by 57, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 11677.92982456
Subtracting 342 from 350 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 11677.92982456 with a balance of 8e-09.
