We look at the division of 318624 by 99 
We want to figure out the number of times 318624 can be divided by 99.

Step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 99

On to step 2:
99 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 99

On to step 3:
99 can be fit into 318 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 297 from 318 and we're left with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 99

Step 4:
When dividing 216 by 99, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 198 from 216 to get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 99

Going ahead to step 5:
182 divided by 99 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
If we subtract 99 from 182, we get 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 99

Moving on to step 6:
834 divided by 99 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 3218.0
Subtract 792 from 834 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
The number 99 fits into 420 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 3218.4
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
When dividing 240 by 99, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 3218.42
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
99 can be fit into 420 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 3218.424
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 99, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 3218.4242
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
If we divide 420 by 99, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 3218.42424
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
If we divide 240 by 99, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 3218.424242
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
99 goes into 420 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 3218.4242424
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 99 is 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 3218.42424242
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 3218.42424242 with a remaining 4.2e-08.
