We're dividing 815436 by 57 
The aim is to understand the frequency of 57 in 815436.

Advancing to step 1:
57 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 57

Step 2:
When dividing 81 by 57, we get 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 24 after subtracting 57 from 81.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 57

Step 3:
57 can be fit into 245 4 times, resulting in a remainder of 17.
The next digit of our result is 4. 
Result so far: 14.0
If we take 228 away from 245, we end up with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 57

Moving on to step 4:
57 goes into 174 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 171 from 174 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 57

Moving on to step 5:
If we divide 33 by 57, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 1430.0
If we subtract 0 from 33, we get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 57

Going ahead to step 6:
If we divide 336 by 57, we get 5 and a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 14305.0
Deduct 285 from 336 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 7:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 14305.8
If we subtract 456 from 510, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
57 goes into 540 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 14305.89
The remainder is 27 after subtracting 513 from 540.
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 9:
270 divided by 57 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 14305.894
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.

On to step 10:
The number 57 fits into 420 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 14305.8947
Deduct 399 from 420 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 14305.89473
Deduct 171 from 210 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
57 can be fit into 390 6 times, resulting in a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 14305.894736
Deduct 342 from 390 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
480 divided by 57 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 14305.8947368
Subtracting 456 from 480 leaves us 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.

Step 14:
240 divided by 57 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 14305.89473684
Deduct 228 from 240 and we're left 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.

Our division results in 14305.89473684 with a remaining 1.2e-08.
