We look at the division of 742568 by 1 
We want to divide 742568 by 1.

Advancing to step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Moving on to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 74.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 3:
1 goes into 2 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 742.0
If we subtract 2 from 2, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

On to step 4:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7425.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Going ahead to step 5:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 74256.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Let's proceed to step 6:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 742568.0
The remainder is 0 after subtracting 8 from 8.
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 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 742568.0
Deduct 0 from 0 and we're left 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.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 742568.0
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.

The final outcome is 742568.0, with a leftover of 0.0.
