749603 ÷ 12 
We want to divide 749603 by 12.

On to step 1:
12 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 12

Going ahead to step 2:
12 can be fit into 74 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 72 from 74 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 12

Let's proceed to step 3:
29 divided by 12 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtract 24 from 29 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 12

Moving on to step 4:
When dividing 56 by 12, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 624.0
If we subtract 48 from 56, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 12

Going ahead to step 5:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6246.0
If we subtract 72 from 80, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 12

Step 6:
83 divided by 12 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 62466.0
If we subtract 72 from 83, 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.

Advancing to step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 62466.9
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 62466.91
If we subtract 12 from 20, 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.

On to step 9:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 62466.916
If we take 72 away from 80, we end up 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.

Moving on to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 62466.9166
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.

The final result is 62466.9166 with a remainder of 8e-05.
