91663 divided by 12 
We're looking to find how many times 12 goes into 91663.

On to step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

On to step 2:
12 goes into 91 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 84 from 91 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 12

Step 3:
The number 12 fits into 76 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
The remainder is 4 after subtracting 72 from 76.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 12

Let's proceed to step 4:
If we divide 46 by 12, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 763.0
If we subtract 36 from 46, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 12

Going ahead to step 5:
12 goes into 103 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 7638.0
If we subtract 96 from 103, 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.

Advancing to step 6:
70 divided by 12 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7638.5
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:
When dividing 100 by 12, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 7638.58
If we take 96 away from 100, we end up 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.

On to step 8:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 7638.583
If we take 36 away from 40, we end up 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.

On to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 7638.5833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 7638.5833 with a remainder of 4e-05.
