803743 divided by 12 
We want to divide 803743 by 12.

Step 1:
12 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 12

Let's proceed to step 2:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 72 from 80 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 12

On to step 3:
The number 12 fits into 83 6 times, leaving a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 72 from 83 leaves us with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 12

Step 4:
If we divide 117 by 12, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 669.0
If we subtract 108 from 117, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 12

Let's proceed to step 5:
94 divided by 12 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 6697.0
Subtracting 84 from 94 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

Moving on to step 6:
When dividing 103 by 12, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 66978.0
Subtracting 96 from 103 leaves us with 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 7:
70 divided by 12 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 66978.5
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.

Going ahead to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 66978.58
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.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 66978.583
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 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 66978.5833
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.

After the division, we end up with 66978.5833 and a remainder of 4e-05.
