9648670 ÷ 80 
We want to divide 9648670 by 80.

Moving on to step 1:
80 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 80

Going ahead to step 2:
When dividing 96 by 80, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 80 from 96, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 80

Let's proceed to step 3:
When dividing 164 by 80, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 160 from 164 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 80

Moving on to step 4:
The number 80 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtracting 0 from 48 leaves us with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 80

On to step 5:
When dividing 486 by 80, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 1206.0
Subtracting 480 from 486 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 80

On to step 6:
When dividing 67 by 80, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 12060.0
If we take 0 away from 67, we end up with 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 80

Step 7:
If we divide 670 by 80, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 120608.0
Subtract 640 from 670 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 120608.3
Deduct 240 from 300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
600 divided by 80 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 120608.37
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 120608.375
Subtract 400 from 400 to 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.

Let's proceed to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 120608.375
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.

Step 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 120608.375
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.

The final outcome is 120608.375, with a leftover of 0.0.
