Let's divide 840784 by 1
We're looking to find how many times 1 goes into 840784.

Advancing to step 1:
If we divide 8 by 1, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 8 away from 8, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Going ahead to step 2:
4 divided by 1 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Step 3:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 840.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Step 4:
If we divide 7 by 1, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 8407.0
If we subtract 7 from 7, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Advancing to step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 84078.0
Subtract 8 from 8 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Advancing to step 6:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 840784.0
The remainder is 0 after subtracting 4 from 4.
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.
The number 0 becomes the next digit in our result. 
Result so far: 840784.0
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.

Going ahead to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 840784.0
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 840784.0 with a remaining 0.0.
