960658 ÷ 99 
The aim is to understand the frequency of 99 in 960658.

Advancing to step 1:
9 divided by 99 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 99

Moving on to step 2:
99 goes into 96 0 times with a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 96 leaves us with 96.
Grab the next digit (0) from the dividend, add it to 96, then carry on: 960 / 99

Step 3:
If we divide 960 by 99, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 891 from 960, we get 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 99

Moving on to step 4:
The number 99 fits into 696 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 693 from 696 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 99

Step 5:
99 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 970.0
If we subtract 0 from 35, we get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 99

On to step 6:
99 goes into 358 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 9703.0
Subtract 297 from 358 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
The number 99 fits into 610 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 9703.6
Deduct 594 from 610 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
If we divide 160 by 99, we get 1 and a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 9703.61
If we subtract 99 from 160, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
When dividing 610 by 99, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 9703.616
Subtracting 594 from 610 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
The number 99 fits into 160 1 times, leaving a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 9703.6161
If we take 99 away from 160, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 11:
The number 99 fits into 610 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 9703.61616
Subtracting 594 from 610 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
The number 99 fits into 160 1 times, leaving a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 9703.616161
If we subtract 99 from 160, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 13:
99 goes into 610 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 9703.6161616
If we take 594 away from 610, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
When dividing 160 by 99, we get 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 9703.61616161
Subtracting 99 from 160 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 9703.61616161, with a leftover of 6.1e-08.
