78670 divided by 9 
We want to divide 78670 by 9.

Going ahead to step 1:
When dividing 7 by 9, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 9

Let's proceed to step 2:
If we divide 78 by 9, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 72 from 78 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 9

Moving on to step 3:
When dividing 66 by 9, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
The remainder is 3 after subtracting 63 from 66.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 9

Advancing to step 4:
37 divided by 9 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 874.0
Subtracting 36 from 37 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 9

Let's proceed to step 5:
9 can be fit into 10 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 8741.0
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
10 divided by 9 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 8741.1
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 9 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 8741.11
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 8741.11 and a remainder of 0.001.
