We're dividing 680633 by 99 
The aim is to understand the frequency of 99 in 680633.

Advancing to step 1:
6 divided by 99 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 99

Going ahead to step 2:
The number 99 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 99

Going ahead to step 3:
If we divide 680 by 99, we get 6 and a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 86 after subtracting 594 from 680.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 99

Moving on to step 4:
If we divide 866 by 99, we get 8 and a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we subtract 792 from 866, we get 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 99

Advancing to step 5:
99 can be fit into 743 7 times, resulting in a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 687.0
Deduct 693 from 743 and we're left with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 99

Going ahead to step 6:
503 divided by 99 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 6875.0
Subtracting 495 from 503 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 99, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6875.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
99 goes into 800 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 6875.08
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 99 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6875.08
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
99 goes into 800 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 6875.0808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
When dividing 80 by 99, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6875.0808
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
99 goes into 800 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 6875.080808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
99 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6875.080808
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
When dividing 800 by 99, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 6875.08080808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 6875.08080808, and the remainder is 8e-09.
