We divide 391655 by 12
We want to figure out the number of times 391655 can be divided by 12.

Step 1:
12 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 12

Let's proceed to step 2:
When dividing 39 by 12, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 36 from 39 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 12

Going ahead to step 3:
12 goes into 31 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 24 from 31 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 12

Going ahead to step 4:
76 divided by 12 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 326.0
If we take 72 away from 76, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 12

Advancing to step 5:
If we divide 45 by 12, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3263.0
Deduct 36 from 45 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 12

Step 6:
The number 12 fits into 95 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 32637.0
If we subtract 84 from 95, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 32637.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 12 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 32637.91
If we subtract 12 from 20, we 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 9:
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: 32637.916
If we take 72 away from 80, 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.

Going ahead to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 32637.9166
If we subtract 72 from 80, we 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.

After the division, we end up with 32637.9166 and a remainder of 8e-05.
