754738 ÷ 12 
We want to figure out the number of times 754738 can be divided by 12.

Step 1:
7 divided by 12 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 12

Step 2:
The number 12 fits into 75 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 72 away from 75, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 12

On to step 3:
12 goes into 34 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 62.0
Deduct 24 from 34 and we're left with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 12

Advancing to step 4:
When dividing 107 by 12, we get 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 628.0
If we subtract 96 from 107, we get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 12

Advancing to step 5:
113 divided by 12 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 6289.0
Subtracting 108 from 113 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 12

Going ahead to step 6:
58 divided by 12 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 62894.0
Subtract 48 from 58 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 12, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 62894.8
Deduct 96 from 100 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.

Advancing to step 8:
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: 62894.83
Subtracting 36 from 40 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.

Going ahead to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 62894.833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 62894.833 with a remaining 0.0004.
