Let's divide 811803 by 1
We want to divide 811803 by 1.

Going ahead to step 1:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Going ahead to step 2:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 81.0
If we subtract 1 from 1, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

On to step 3:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 811.0
If we subtract 1 from 1, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Going ahead to step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8118.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Moving on to step 5:
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: 81180.0
If we subtract 0 from 0, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Moving on to step 6:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 811803.0
Deduct 3 from 3 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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 811803.0
Subtracting 0 from 0 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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 811803.0
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.

In conclusion, the division gives 811803.0 with a balance of 0.0.
