We look at the division of 786436 by 80 
We want to figure out the number of times 786436 can be divided by 80.

On to step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 80

Step 2:
The number 80 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 80

Step 3:
80 goes into 786 9 times with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 720 from 786 and we're left with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 80

Going ahead to step 4:
The number 80 fits into 664 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtract 640 from 664 to get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 80

On to step 5:
When dividing 243 by 80, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 983.0
If we subtract 240 from 243, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 80

Let's proceed to step 6:
If we divide 36 by 80, we get 0 and a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 9830.0
Subtract 0 from 36 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
80 can be fit into 360 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 9830.4
The remainder is 40 after subtracting 320 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9830.45
The remainder is 0 after subtracting 400 from 400.
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 9:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9830.45
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.

Let's proceed to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9830.45
If we take 0 away from 0, 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.

Our division results in 9830.45 with a remaining 0.0.
