Let's divide 753381 by 99
The aim is to understand the frequency of 99 in 753381.

Moving on to step 1:
99 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 99

Moving on to step 2:
99 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 99

Step 3:
99 can be fit into 753 7 times, resulting in a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 693 from 753 leaves us with 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 99

Advancing to step 4:
99 goes into 603 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtracting 594 from 603 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 99

Moving on to step 5:
When dividing 98 by 99, we get 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 760.0
If we take 0 away from 98, we end up with 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 99

Going ahead to step 6:
If we divide 981 by 99, we get 9 and a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 7609.0
If we take 891 away from 981, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 7:
99 goes into 900 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 7609.9
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
When dividing 90 by 99, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 7609.9
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 9:
If we divide 900 by 99, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 7609.909
If we subtract 891 from 900, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
When dividing 90 by 99, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 7609.909
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
99 goes into 900 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 7609.90909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
99 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 7609.90909
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
99 goes into 900 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 7609.9090909
Deduct 891 from 900 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
If we divide 90 by 99, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 7609.9090909
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 7609.9090909 and a remainder of 9e-08.
