99812989 divided by 760 
The aim is to understand the frequency of 760 in 99812989.

Step 1:
The number 760 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 760

Moving on to step 2:
The number 760 fits into 99 0 times, leaving a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 760

Step 3:
760 can be fit into 998 1 times, resulting in a remainder of 238.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 760 from 998 leaves us with 238.
Bring next digit (1) of the dividend behind the 238 and repeat the process: 2381 / 760

On to step 4:
2381 divided by 760 is 3 with a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 2280 from 2381, we get 101.
Include the next digit (2) from the dividend after 101, then repeat: 1012 / 760

Going ahead to step 5:
When dividing 1012 by 760, we get 1 with a remainder of 252.
The next digit of our result is 1. 
Result so far: 131.0
The remainder is 252 after subtracting 760 from 1012.
Grab the next digit (9) from the dividend, add it to 252, then carry on: 2529 / 760

Moving on to step 6:
760 goes into 2529 3 times with a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 1313.0
If we take 2280 away from 2529, we end up with 249.
Take the next digit (8) from the dividend and append it to 249, then repeat: 2498 / 760

Advancing to step 7:
760 goes into 2498 3 times with a remainder of 218.
The number 3 becomes the next digit in our result. 
Result so far: 13133.0
Subtracting 2280 from 2498 leaves us with 218.
Include the next digit (9) from the dividend after 218, then repeat: 2189 / 760

Going ahead to step 8:
2189 divided by 760 is 2 with a remainder of 669.
Use 2 as the next digit of our solution. 
Result so far: 131332.0
Subtract 1520 from 2189 to get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Advancing to step 9:
760 can be fit into 6690 8 times, resulting in a remainder of 610.
Put 8 as the next digit of the answer. 
Result so far: 131332.8
If we subtract 6080 from 6690, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 10:
The number 760 fits into 6100 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 131332.88
Subtract 6080 from 6100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 131332.88 with a remaining 0.02.
