We look at the division of 748485 by 1 
We're looking to find how many times 1 goes into 748485.

Let's proceed to step 1:
If we divide 7 by 1, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 7 from 7 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 2:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 3:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 748.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Step 4:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 7484.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 5:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 74848.0
If we subtract 8 from 8, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

On to step 6:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 748485.0
Subtracting 5 from 5 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.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 748485.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 748485.0
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.

The final result is 748485.0 with a remainder of 0.0.
