Let's divide 988253 by 57
The aim is to understand the frequency of 57 in 988253.

Advancing to step 1:
If we divide 9 by 57, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 57

On to step 2:
The number 57 fits into 98 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 57 from 98 leaves us with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 57

Step 3:
The number 57 fits into 418 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 399 from 418 leaves us with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 57

Advancing to step 4:
192 divided by 57 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtracting 171 from 192 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 57

Let's proceed to step 5:
The number 57 fits into 215 3 times, leaving a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 1733.0
Deduct 171 from 215 and we're left with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 57

Step 6:
57 can be fit into 443 7 times, resulting in a remainder of 44.
The next digit of our result is 7. 
Result so far: 17337.0
Subtract 399 from 443 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
440 divided by 57 is 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 17337.7
Subtract 399 from 440 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
410 divided by 57 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 17337.77
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 17337.77 with a remaining 0.011.
