We look at the division of 451368 by 1 
We want to divide 451368 by 1.

Step 1:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 4 from 4 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 2:
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: 45.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Let's proceed to step 3:
1 divided by 1 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 451.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

On to step 4:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 4513.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Moving on to step 5:
If we divide 6 by 1, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 45136.0
If we take 6 away from 6, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 6:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 451368.0
If we subtract 8 from 8, 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.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 451368.0
If we take 0 away from 0, 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.

Going ahead to step 8:
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: 451368.0
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 result is 451368.0 with a remainder of 0.0.
