We're dividing 398932 by 99 
Let's see how many times 99 fits into 398932.

Step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 99

Going ahead to step 2:
If we divide 39 by 99, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 99

On to step 3:
99 goes into 398 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 396 from 398 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 99

Let's proceed to step 4:
When dividing 29 by 99, we get 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 29 to get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 99

Step 5:
99 goes into 293 2 times with a remainder of 95.
Put 2 as the next digit of the answer. 
Result so far: 402.0
If we subtract 198 from 293, we get 95.
Bring next digit (2) of the dividend behind the 95 and repeat the process: 952 / 99

Step 6:
99 goes into 952 9 times with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 4029.0
Deduct 891 from 952 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
If we divide 610 by 99, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4029.6
If we take 594 away from 610, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
99 goes into 160 1 times with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 4029.61
The remainder is 61 after subtracting 99 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
The number 99 fits into 610 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 4029.616
Subtract 594 from 610 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 99 is 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 4029.6161
If we subtract 99 from 160, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
When dividing 610 by 99, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 4029.61616
The remainder is 16 after subtracting 594 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
99 goes into 160 1 times with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 4029.616161
Subtract 99 from 160 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 13:
When dividing 610 by 99, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 4029.6161616
The remainder is 16 after subtracting 594 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
99 goes into 160 1 times with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 4029.61616161
The remainder is 61 after subtracting 99 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 4029.61616161 and a remainder of 6.1e-08.
