We look at the division of 374034 by 99 
The aim is to understand the frequency of 99 in 374034.

On to step 1:
When dividing 3 by 99, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 99

On to step 2:
When dividing 37 by 99, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 99

Let's proceed to step 3:
The number 99 fits into 374 3 times, leaving a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 297 away from 374, we end up with 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 99

Let's proceed to step 4:
99 goes into 770 7 times with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 77 after subtracting 693 from 770.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 99

Going ahead to step 5:
99 goes into 773 7 times with a remainder of 80.
Write down 7 as next digit of the result. 
Result so far: 377.0
If we take 693 away from 773, we end up with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 99

Let's proceed to step 6:
99 goes into 804 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3778.0
Deduct 792 from 804 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 99 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 3778.1
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
When dividing 210 by 99, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3778.12
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
99 goes into 120 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 3778.121
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
If we divide 210 by 99, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 3778.1212
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
99 can be fit into 120 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 3778.12121
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
99 can be fit into 210 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3778.121212
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
If we divide 120 by 99, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 3778.1212121
Deduct 99 from 120 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
99 goes into 210 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 3778.12121212
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 3778.12121212 with a remaining 1.2e-08.
