We divide 878060 by 99
The aim is to understand the frequency of 99 in 878060.

Step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 99

Advancing to step 2:
99 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 99

Step 3:
878 divided by 99 is 8 with a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 86 after subtracting 792 from 878.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 99

Going ahead to step 4:
99 goes into 860 8 times with a remainder of 68.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 68 after subtracting 792 from 860.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 99

Advancing to step 5:
99 can be fit into 686 6 times, resulting in a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 886.0
Deduct 594 from 686 and we're left with 92.
Take the next digit (0) from the dividend and append it to 92, then repeat: 920 / 99

Advancing to step 6:
When dividing 920 by 99, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 8869.0
If we subtract 891 from 920, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
The number 99 fits into 290 2 times, leaving a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 8869.2
Subtracting 198 from 290 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 8:
99 goes into 920 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 8869.29
Subtract 891 from 920 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
290 divided by 99 is 2 with a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 8869.292
If we take 198 away from 290, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
99 can be fit into 920 9 times, resulting in a remainder of 29.
The next digit of our result is 9. 
Result so far: 8869.2929
Subtract 891 from 920 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
The number 99 fits into 290 2 times, leaving a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 8869.29292
Deduct 198 from 290 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
The number 99 fits into 920 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 8869.292929
If we subtract 891 from 920, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
If we divide 290 by 99, we get 2 and a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 8869.2929292
Subtracting 198 from 290 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 14:
99 goes into 920 9 times with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 8869.29292929
Subtracting 891 from 920 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 8869.29292929, with a leftover of 2.9e-08.
