913207 divided by 99 
The aim is to understand the frequency of 99 in 913207.

On to step 1:
If we divide 9 by 99, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 99

Step 2:
99 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Fetch the next digit (3) from the dividend, attach it to 91 and continue: 913 / 99

Advancing to step 3:
If we divide 913 by 99, we get 9 and a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 22 after subtracting 891 from 913.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 99

On to step 4:
222 divided by 99 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we take 198 away from 222, we end up with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 99

Moving on to step 5:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 922.0
The remainder is 42 after subtracting 198 from 240.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 99

On to step 6:
The number 99 fits into 427 4 times, leaving a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 9224.0
If we subtract 396 from 427, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
The number 99 fits into 310 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 9224.3
Subtract 297 from 310 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 99, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 9224.31
If we take 99 away from 130, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
99 can be fit into 310 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 9224.313
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
When dividing 130 by 99, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 9224.3131
The remainder is 31 after subtracting 99 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
The number 99 fits into 310 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 9224.31313
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
130 divided by 99 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 9224.313131
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
The number 99 fits into 310 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 9224.3131313
The remainder is 13 after subtracting 297 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
The number 99 fits into 130 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 9224.31313131
Deduct 99 from 130 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 9224.31313131 with a balance of 3.1e-08.
