125073 ÷ 99 
The aim is to understand the frequency of 99 in 125073.

On to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 99

Going ahead to step 2:
The number 99 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 99

Let's proceed to step 3:
The number 99 fits into 125 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 99 from 125 to get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 99

Advancing to step 4:
99 can be fit into 260 2 times, resulting in a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 62 after subtracting 198 from 260.
Take the next digit (7) from the dividend and append it to 62, then repeat: 627 / 99

On to step 5:
The number 99 fits into 627 6 times, leaving a remainder of 33.
The next digit of our result is 6. 
Result so far: 126.0
Subtract 594 from 627 to get 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 99

Step 6:
When dividing 333 by 99, we get 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 1263.0
Deduct 297 from 333 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.

Going ahead to step 7:
If we divide 360 by 99, we get 3 and a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 1263.3
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.

Going ahead to step 8:
630 divided by 99 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 1263.36
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 9:
When dividing 360 by 99, we get 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 1263.363
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.

Let's proceed to step 10:
630 divided by 99 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 1263.3636
If we take 594 away from 630, we end up 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 11:
99 can be fit into 360 3 times, resulting in a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 1263.36363
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.

Moving on to step 12:
When dividing 630 by 99, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 1263.363636
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.

Going ahead to step 13:
99 can be fit into 360 3 times, resulting in a remainder of 63.
The next digit of our result is 3. 
Result so far: 1263.3636363
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.

Going ahead to step 14:
99 goes into 630 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1263.36363636
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.

The final outcome is 1263.36363636, with a leftover of 3.6e-08.
