57817519 ÷ 728 
The aim is to understand the frequency of 728 in 57817519.

On to step 1:
5 divided by 728 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 728

Step 2:
When dividing 57 by 728, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 728

Going ahead to step 3:
When dividing 578 by 728, we get 0 with a remainder of 578.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 578, we end up with 578.
Bring next digit (1) of the dividend behind the 578 and repeat the process: 5781 / 728

Moving on to step 4:
728 goes into 5781 7 times with a remainder of 685.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 5096 from 5781 to get 685.
Grab the next digit (7) from the dividend, add it to 685, then carry on: 6857 / 728

Let's proceed to step 5:
The number 728 fits into 6857 9 times, leaving a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 6552 from 6857 and we're left with 305.
Grab the next digit (5) from the dividend, add it to 305, then carry on: 3055 / 728

Advancing to step 6:
728 goes into 3055 4 times with a remainder of 143.
Use 4 as the next digit of our solution. 
Result so far: 794.0
Subtract 2912 from 3055 to get 143.
Bring next digit (1) of the dividend behind the 143 and repeat the process: 1431 / 728

Moving on to step 7:
The number 728 fits into 1431 1 times, leaving a remainder of 703.
The number 1 becomes the next digit in our result. 
Result so far: 7941.0
If we subtract 728 from 1431, we get 703.
Bring next digit (9) of the dividend behind the 703 and repeat the process: 7039 / 728

Going ahead to step 8:
7039 divided by 728 is 9 with a remainder of 487.
Write down 9 as next digit of the result. 
Result so far: 79419.0
Deduct 6552 from 7039 and we're left with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Moving on to step 9:
If we divide 4870 by 728, we get 6 and a remainder of 502.
The number 6 becomes the next digit in our result. 
Result so far: 79419.6
Subtracting 4368 from 4870 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 10:
728 can be fit into 5020 6 times, resulting in a remainder of 652.
Put 6 as the next digit of the answer. 
Result so far: 79419.66
If we take 4368 away from 5020, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Our division results in 79419.66 with a remaining 0.652.
