798356 divided by 12 
Our goal is to divide 798356 by 12.

On to step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Going ahead to step 2:
If we divide 79 by 12, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 72 away from 79, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

Going ahead to step 3:
If we divide 78 by 12, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 6 after subtracting 72 from 78.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 12

Step 4:
The number 12 fits into 63 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 665.0
Deduct 60 from 63 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 12

Advancing to step 5:
35 divided by 12 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 6652.0
Subtract 24 from 35 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Going ahead to step 6:
If we divide 116 by 12, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 66529.0
The remainder is 8 after subtracting 108 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 66529.6
Deduct 72 from 80 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.

Step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 66529.66
Deduct 72 from 80 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.

After the division, we end up with 66529.66 and a remainder of 0.008.
