222579 divided by 57 
The aim is to understand the frequency of 57 in 222579.

Going ahead to step 1:
When dividing 2 by 57, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 57

On to step 2:
The number 57 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0

510 divided by 57 is 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 3904.8
Subtract 456 from 510 to 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:
If we divide 540 by 57, we get 9 and a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 3904.89
Subtracting 513 from 540 leaves us 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.

Step 9:
57 can be fit into 270 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 3904.894
If we subtract 228 from 270, we get 42.
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.
Put 7 as the next digit of the answer. 
Result so far: 3904.8947
The remainder is 21 after subtracting 399 from 420.
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:
If we divide 210 by 57, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 3904.89473
If we subtract 171 from 210, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on 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: 3904.894736
Subtracting 342 from 390 leaves us 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.

Advancing to step 13:
If we divide 480 by 57, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3904.8947368
Deduct 456 from 480 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.

Moving on to step 14:
57 can be fit into 240 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3904.89473684
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.

After the division, we end up with 3904.89473684 and a remainder of 1.2e-08.
