We're dividing 931990 by 12 
We're looking to find how many times 12 goes into 931990.

Moving on to step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 12

Moving on to step 2:
93 divided by 12 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 84 from 93 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

On to step 3:
91 divided by 12 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 84 from 91 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

Moving on to step 4:
12 goes into 79 6 times with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 776.0
The remainder is 7 after subtracting 72 from 79.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

Step 5:
79 divided by 12 is 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 7766.0
If we take 72 away from 79, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 12

Advancing to step 6:
When dividing 70 by 12, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 77665.0
Subtract 60 from 70 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 77665.8
Subtract 96 from 100 to 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.

On to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 77665.83
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.

On to step 9:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 77665.833
Subtracting 36 from 40 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.

The quotient of the division is 77665.833, and the remainder is 0.0004.
