Let's divide 91307837 by 12
We want to divide 91307837 by 12.

Advancing to step 1:
9 divided by 12 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 12

Let's proceed to step 2:
12 can be fit into 91 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 84 from 91, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 12

Advancing to step 3:
If we divide 73 by 12, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 72 from 73, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 12

Moving on to step 4:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 760.0
If we subtract 0 from 10, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 12

Going ahead to step 5:
12 goes into 107 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 7608.0
Subtract 96 from 107 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 12

Moving on to step 6:
When dividing 118 by 12, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 76089.0
If we subtract 108 from 118, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 12

Let's proceed to step 7:
12 goes into 103 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 760898.0
If we take 96 away from 103, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 12

Advancing to step 8:
If we divide 77 by 12, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 7608986.0
Subtract 72 from 77 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
If we divide 50 by 12, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 7608986.4
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 7608986.41
Deduct 12 from 20 and we're left 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.

Advancing to step 11:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7608986.416
Subtract 72 from 80 to 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.

Going ahead to step 12:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 7608986.4166
Subtracting 72 from 80 leaves us 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.

The final result is 7608986.4166 with a remainder of 8e-05.
