Let's divide 398183 by 12
We want to divide 398183 by 12.

On to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 12

Step 2:
39 divided by 12 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 3 after subtracting 36 from 39.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 12

Moving on to step 3:
38 divided by 12 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 36 from 38, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 12

Step 4:
21 divided by 12 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 331.0
If we take 12 away from 21, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 12

Step 5:
12 goes into 98 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 3318.0
If we subtract 96 from 98, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 12

Moving on to step 6:
When dividing 23 by 12, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 33181.0
Deduct 12 from 23 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
110 divided by 12 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 33181.9
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 12 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 33181.91
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 33181.916
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 33181.9166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 33181.9166 with a remainder of 8e-05.
