813799 ÷ 1 
Let's see how many times 1 fits into 813799.

Going ahead to step 1:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Step 2:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 3:
3 divided by 1 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 813.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Let's proceed to step 4:
7 divided by 1 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 8137.0
If we take 7 away from 7, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

On to step 5:
9 divided by 1 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 81379.0
If we take 9 away from 9, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Step 6:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 813799.0
Deduct 9 from 9 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.

Going ahead to step 7:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 813799.0
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.

Going ahead to step 8:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 813799.0
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.

The final outcome is 813799.0, with a leftover of 0.0.
