We're dividing 59986 by 99 
The aim is to understand the frequency of 99 in 59986.

Let's proceed to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 99

On to step 2:
When dividing 59 by 99, we get 0 with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 99

Let's proceed to step 3:
The number 99 fits into 599 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 594 away from 599, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 99

Step 4:
If we divide 58 by 99, we get 0 and a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtract 0 from 58 to get 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 99

Going ahead to step 5:
When dividing 586 by 99, we get 5 with a remainder of 91.
Use 5 as the next digit of our solution. 
Result so far: 605.0
Subtracting 495 from 586 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 6:
99 goes into 910 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 605.9
If we subtract 891 from 910, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
99 goes into 190 1 times with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 605.91
Deduct 99 from 190 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 8:
The number 99 fits into 910 9 times, leaving a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 605.919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
The number 99 fits into 190 1 times, leaving a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 605.9191
Subtracting 99 from 190 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 10:
If we divide 910 by 99, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 605.91919
If we subtract 891 from 910, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
The number 99 fits into 190 1 times, leaving a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 605.919191
Subtract 99 from 190 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 12:
If we divide 910 by 99, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 605.9191919
The remainder is 19 after subtracting 891 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
When dividing 190 by 99, we get 1 with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 605.91919191
If we subtract 99 from 190, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final result is 605.91919191 with a remainder of 9.1e-08.
