We're dividing 189493 by 99 
The aim is to understand the frequency of 99 in 189493.

On to step 1:
If we divide 1 by 99, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 99

Step 2:
When dividing 18 by 99, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 99

On to step 3:
If we divide 189 by 99, we get 1 and a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 90 after subtracting 99 from 189.
Take the next digit (4) from the dividend and append it to 90, then repeat: 904 / 99

Let's proceed to step 4:
If we divide 904 by 99, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 891 from 904 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 99

Moving on to step 5:
99 goes into 139 1 times with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Subtract 99 from 139 to get 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 99

On to step 6:
If we divide 403 by 99, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 1914.0
Subtract 396 from 403 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
99 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1914.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
700 divided by 99 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 1914.07
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
When dividing 70 by 99, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 1914.07
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
99 can be fit into 700 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1914.0707
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
The number 99 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1914.0707
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
700 divided by 99 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 1914.070707
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
If we divide 70 by 99, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1914.070707
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
99 goes into 700 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1914.07070707
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 1914.07070707 with a remaining 7e-09.
