70796431 divided by 12 
Our goal is to divide 70796431 by 12.

Step 1:
When dividing 7 by 12, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 12

On to step 2:
70 divided by 12 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 60 from 70 to get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 12

Moving on to step 3:
The number 12 fits into 107 8 times, leaving a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we subtract 96 from 107, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 12

On to step 4:
12 goes into 119 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 589.0
If we take 108 away from 119, we end up with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

On to step 5:
When dividing 116 by 12, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 5899.0
If we subtract 108 from 116, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 12

On to step 6:
When dividing 84 by 12, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 58997.0
Deduct 84 from 84 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 12

Step 7:
12 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 589970.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 12

Let's proceed to step 8:
The number 12 fits into 31 2 times, leaving a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 5899702.0
If we subtract 24 from 31, 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.

On to step 9:
70 divided by 12 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5899702.5
Deduct 60 from 70 and we're left 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.

On to step 10:
When dividing 100 by 12, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 5899702.58
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.

On to step 11:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 5899702.583
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.

Step 12:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 5899702.5833
Subtract 36 from 40 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.

The final result is 5899702.5833 with a remainder of 4e-05.
