We look at the division of 407591 by 1 
Our goal is to divide 407591 by 1.

Advancing to step 1:
4 divided by 1 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

On to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 0, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Let's proceed to step 3:
When dividing 7 by 1, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 407.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Going ahead to step 4:
5 divided by 1 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4075.0
Deduct 5 from 5 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Going ahead to step 5:
1 goes into 9 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 40759.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Moving on to step 6:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 407591.0
If we take 1 away from 1, we end up 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.

Let's proceed to step 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 407591.0
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.

Going ahead to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 407591.0
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 407591.0, with a leftover of 0.0.
