791872 divided by 1 
We're looking to find how many times 1 goes into 791872.

Step 1:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 7 from 7 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Going ahead to step 2:
If we divide 9 by 1, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

On to step 3:
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: 791.0
Deduct 1 from 1 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Going ahead to step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 7918.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 5:
When dividing 7 by 1, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 79187.0
If we subtract 7 from 7, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

On to step 6:
If we divide 2 by 1, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 791872.0
If we take 2 away from 2, 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.
Put 0 as the next digit of the answer. 
Result so far: 791872.0
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.

Let's proceed 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: 791872.0
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.

The final outcome is 791872.0, with a leftover of 0.0.
