We divide 451981 by 1
We want to divide 451981 by 1.

Advancing to step 1:
4 divided by 1 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 2:
If we divide 5 by 1, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 45.0
If we take 5 away from 5, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Moving on to step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 451.0
If we subtract 1 from 1, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Moving on to step 4:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 4519.0
Subtract 9 from 9 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 5:
8 divided by 1 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 45198.0
Subtract 8 from 8 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Step 6:
1 divided by 1 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 451981.0
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.

On to step 7:
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: 451981.0
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.

Moving on to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 451981.0
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.

Our division results in 451981.0 with a remaining 0.0.
