We look at the division of 754398 by 12 
We want to figure out the number of times 754398 can be divided by 12.

Moving on to step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 12

Advancing to step 2:
12 goes into 75 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 72 from 75 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Advancing to step 3:
If we divide 34 by 12, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 24 from 34, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 12

Moving on to step 4:
103 divided by 12 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 628.0
The remainder is 7 after subtracting 96 from 103.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 12

Step 5:
12 goes into 79 6 times with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 6286.0
If we take 72 away from 79, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

Advancing to step 6:
12 goes into 78 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 62866.0
Deduct 72 from 78 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
12 goes into 60 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 62866.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 62866.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62866.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 62866.5 with a remaining 0.0.
