We divide 748646 by 10
We want to figure out the number of times 748646 can be divided by 10.

Advancing to step 1:
When dividing 7 by 10, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 10

On to step 2:
74 divided by 10 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 4 after subtracting 70 from 74.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 10

Step 3:
10 goes into 48 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 40 from 48 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 10

Going ahead to step 4:
10 goes into 86 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 748.0
Deduct 80 from 86 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 10

Going ahead to step 5:
When dividing 64 by 10, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 7486.0
Subtract 60 from 64 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 10

Going ahead to step 6:
The number 10 fits into 46 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 74864.0
Subtract 40 from 46 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 10, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 74864.6
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:
When dividing 0 by 10, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 74864.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 74864.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 74864.6 with a remainder of 0.0.
