We're dividing 34831 by 12 
We're looking to find how many times 12 goes into 34831.

Step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 12

Moving on to step 2:
12 goes into 34 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 24 away from 34, we end up with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 12

On to step 3:
When dividing 108 by 12, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 108 from 108 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 12

Advancing to step 4:
12 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 290.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Step 5:
If we divide 31 by 12, we get 2 and a remainder of 7.
The next digit of our result is 2. 
Result so far: 2902.0
If we subtract 24 from 31, we 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.

On to step 6:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2902.5
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2902.58
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2902.583
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 2902.5833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 2902.5833 with a remaining 4e-05.
