We look at the division of 711603 by 57 
The aim is to understand the frequency of 57 in 711603.

Let's proceed to step 1:
57 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 57

Let's proceed to step 2:
If we divide 71 by 57, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 57 from 71 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 57

Step 3:
If we divide 141 by 57, we get 2 and a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 114 from 141 and we're left with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 57

Going ahead to step 4:
The number 57 fits into 276 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtract 228 from 276 to get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 57

On to step 5:
If we divide 480 by 57, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 1248.0
The remainder is 24 after subtracting 456 from 480.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 57

Step 6:
57 goes into 243 4 times with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 12484.0
Subtracting 228 from 243 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
57 can be fit into 150 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 12484.2
The remainder is 36 after subtracting 114 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 57, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 12484.26
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
When dividing 180 by 57, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 12484.263
Deduct 171 from 180 and we're left 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.

Let's proceed to step 10:
When dividing 90 by 57, we get 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 12484.2631
If we take 57 away from 90, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
If we divide 330 by 57, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 12484.26315
Subtracting 285 from 330 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
The number 57 fits into 450 7 times, leaving a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 12484.263157
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 13:
510 divided by 57 is 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 12484.2631578
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 14:
540 divided by 57 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 12484.26315789
Subtract 513 from 540 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 12484.26315789, and the remainder is 2.7e-08.
