748439 divided by 12 
We're looking to find how many times 12 goes into 748439.

On to 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
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 12

On to step 2:
The number 12 fits into 74 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 72 from 74 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 12

Moving on to step 3:
When dividing 28 by 12, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we subtract 24 from 28, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Let's proceed to step 4:
The number 12 fits into 44 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 623.0
Deduct 36 from 44 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 12

Moving on to step 5:
12 can be fit into 83 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6236.0
If we subtract 72 from 83, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 12

Step 6:
12 goes into 119 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 62369.0
If we subtract 108 from 119, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 12 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 62369.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 62369.91
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.

Let's proceed to step 9:
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: 62369.916
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
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: 62369.9166
If we subtract 72 from 80, we 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.

The quotient of the division is 62369.9166, and the remainder is 8e-05.
