We divide 651450 by 99
The aim is to understand the frequency of 99 in 651450.

On to step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 99

Advancing to step 2:
When dividing 65 by 99, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 99

Step 3:
The number 99 fits into 651 6 times, leaving a remainder of 57.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 594 away from 651, we end up with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 99

Advancing to step 4:
99 can be fit into 574 5 times, resulting in a remainder of 79.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 495 away from 574, we end up with 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 99

Step 5:
When dividing 795 by 99, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 658.0
If we take 792 away from 795, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 99

Moving on to step 6:
If we divide 30 by 99, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6580.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
If we divide 300 by 99, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 6580.3
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
The number 99 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 6580.3
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 99 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 6580.303
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
When dividing 30 by 99, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6580.303
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 99, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 6580.30303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
99 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 6580.30303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
300 divided by 99 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 6580.3030303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 6580.3030303
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 6580.3030303 and a remainder of 3e-08.
