We divide 39191088 by 12
Our goal is to divide 39191088 by 12.

Moving on to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 12

Moving on to step 2:
If we divide 39 by 12, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 3 after subtracting 36 from 39.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 12

Moving on to step 3:
12 can be fit into 31 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 24 from 31, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

On to step 4:
79 divided by 12 is 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 326.0
If we take 72 away from 79, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 12

Let's proceed to step 5:
71 divided by 12 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 3265.0
The remainder is 11 after subtracting 60 from 71.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 12

On to step 6:
If we divide 110 by 12, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 32659.0
The remainder is 2 after subtracting 108 from 110.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Advancing to step 7:
The number 12 fits into 28 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 326592.0
Subtracting 24 from 28 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 12

Moving on to step 8:
When dividing 48 by 12, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 3265924.0
Subtract 48 from 48 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3265924.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3265924.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3265924.0 with a remaining 0.0.
