39151 divided by 12 
Let's see how many times 12 fits into 39151.

Moving on to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 12

On to step 2:
12 can be fit into 39 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 12

Step 3:
If we divide 31 by 12, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 24 from 31 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 12

On to step 4:
The number 12 fits into 75 6 times, leaving a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 326.0
Deduct 72 from 75 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 12

Moving on to step 5:
12 goes into 31 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 3262.0
The remainder is 7 after subtracting 24 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 6:
If we divide 70 by 12, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3262.5
If we take 60 away from 70, we end up with 10.
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 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3262.58
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.

Going ahead to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3262.583
If we subtract 36 from 40, we 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.

Going ahead to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3262.5833
Deduct 36 from 40 and we're left 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.

After the division, we end up with 3262.5833 and a remainder of 4e-05.
