625545 divided by 99 
The aim is to understand the frequency of 99 in 625545.

Advancing to step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 99

Going ahead to step 2:
If we divide 62 by 99, we get 0 and a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 99

On to step 3:
99 goes into 625 6 times with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 31 after subtracting 594 from 625.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 99

Moving on to step 4:
315 divided by 99 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 297 away from 315, we end up with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 99

On to step 5:
If we divide 184 by 99, we get 1 and a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 631.0
Deduct 99 from 184 and we're left with 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 99

Going ahead to step 6:
99 can be fit into 855 8 times, resulting in a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 6318.0
Deduct 792 from 855 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
630 divided by 99 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 6318.6
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
99 goes into 360 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 6318.63
Deduct 297 from 360 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
When dividing 630 by 99, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 6318.636
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
99 goes into 360 3 times with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 6318.6363
If we subtract 297 from 360, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 11:
99 can be fit into 630 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 6318.63636
Deduct 594 from 630 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
99 goes into 360 3 times with a remainder of 63.
The next digit of our result is 3. 
Result so far: 6318.636363
Subtract 297 from 360 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 13:
99 can be fit into 630 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 6318.6363636
Deduct 594 from 630 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
When dividing 360 by 99, we get 3 with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 6318.63636363
Subtracting 297 from 360 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 6318.63636363 with a remainder of 6.3e-08.
