We divide 612105 by 99
The aim is to understand the frequency of 99 in 612105.

On to step 1:
99 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 99

Advancing to step 2:
61 divided by 99 is 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 99

Step 3:
If we divide 612 by 99, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 594 from 612 and we're left with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 99

Let's proceed to step 4:
181 divided by 99 is 1 with a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
Deduct 99 from 181 and we're left with 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 99

On to step 5:
If we divide 820 by 99, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 618.0
If we take 792 away from 820, we end up with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 99

Let's proceed to step 6:
The number 99 fits into 285 2 times, leaving a remainder of 87.
Write down 2 as next digit of the result. 
Result so far: 6182.0
Subtracting 198 from 285 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 7:
When dividing 870 by 99, we get 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 6182.8
Subtract 792 from 870 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
99 can be fit into 780 7 times, resulting in a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 6182.87
Subtracting 693 from 780 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 9:
99 goes into 870 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 6182.878
The remainder is 78 after subtracting 792 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
99 can be fit into 780 7 times, resulting in a remainder of 87.
The next digit of our result is 7. 
Result so far: 6182.8787
The remainder is 87 after subtracting 693 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 11:
If we divide 870 by 99, we get 8 and a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 6182.87878
If we subtract 792 from 870, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 12:
780 divided by 99 is 7 with a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 6182.878787
If we take 693 away from 780, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 13:
99 goes into 870 8 times with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 6182.8787878
Subtract 792 from 870 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 14:
If we divide 780 by 99, we get 7 and a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 6182.87878787
Deduct 693 from 780 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 6182.87878787 and a remainder of 8.7e-08.
