We're dividing 602203 by 57 
The aim is to understand the frequency of 57 in 602203.

Advancing 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
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 57

On to step 2:
If we divide 60 by 57, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 57 from 60, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 57

On to step 3:
32 divided by 57 is 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 32 leaves us with 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 57

Going ahead to step 4:
The number 57 fits into 322 5 times, leaving a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 105.0
The remainder is 37 after subtracting 285 from 322.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 57

On to step 5:
370 divided by 57 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 1056.0
If we take 342 away from 370, we end up with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 57

Going ahead to step 6:
57 can be fit into 283 4 times, resulting in a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 10564.0
The remainder is 55 after subtracting 228 from 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
57 can be fit into 550 9 times, resulting in a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 10564.9
If we subtract 513 from 550, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
370 divided by 57 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 10564.96
Subtract 342 from 370 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
57 can be fit into 280 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 10564.964
Deduct 228 from 280 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
57 can be fit into 520 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 10564.9649
The remainder is 7 after subtracting 513 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
57 can be fit into 70 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 10564.96491
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
If we divide 130 by 57, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 10564.964912
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
If we divide 160 by 57, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 10564.9649122
Subtract 114 from 160 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 10564.9649122, with a leftover of 4.6e-07.
