We divide 125370 by 99
The aim is to understand the frequency of 99 in 125370.

Moving on to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 99

Step 2:
99 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 99

Step 3:
If we divide 125 by 99, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 99 from 125 to get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 99

Going ahead to step 4:
When dividing 263 by 99, we get 2 with a remainder of 65.
The next digit of our result is 2. 
Result so far: 12.0
If we take 198 away from 263, we end up with 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 99

Going ahead to step 5:
When dividing 657 by 99, we get 6 with a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 594 from 657 and we're left with 63.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 99

Step 6:
99 can be fit into 630 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1266.0
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.

On to step 7:
The number 99 fits into 360 3 times, leaving a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 1266.3
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.

On to step 8:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.36
If we subtract 594 from 630, we get 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 9:
If we divide 360 by 99, we get 3 and a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 1266.363
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.

Let's proceed to step 10:
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: 1266.3636
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.

Step 11:
99 goes into 360 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 1266.36363
The remainder is 63 after subtracting 297 from 360.
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 12:
When dividing 630 by 99, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1266.363636
Subtract 594 from 630 to get 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 13:
99 goes into 360 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 1266.3636363
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.

Step 14:
99 can be fit into 630 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1266.36363636
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.

After the division, we end up with 1266.36363636 and a remainder of 3.6e-08.
