Let's divide 780397 by 9
We want to divide 780397 by 9.

Advancing to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 9

Moving on to step 2:
78 divided by 9 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 72 from 78 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 9

Let's proceed to step 3:
When dividing 60 by 9, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Deduct 54 from 60 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 9

Let's proceed to step 4:
9 can be fit into 63 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 867.0
Subtracting 63 from 63 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 9

Moving on to step 5:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 8671.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 9

Let's proceed to step 6:
When dividing 7 by 9, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 86710.0
If we subtract 0 from 7, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 86710.7
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 86710.77
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 86710.77, and the remainder is 0.007.
