We're dividing 84225648 by 80 
Let's see how many times 80 fits into 84225648.

Advancing to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 80

Step 2:
80 goes into 84 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 80 from 84 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 80

Moving on to step 3:
When dividing 42 by 80, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 42, we get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 80

Going ahead to step 4:
If we divide 422 by 80, we get 5 and a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we subtract 400 from 422, we get 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 80

Let's proceed to step 5:
80 goes into 225 2 times with a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 1052.0
The remainder is 65 after subtracting 160 from 225.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 80

On to step 6:
The number 80 fits into 656 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 10528.0
If we subtract 640 from 656, we get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 80

On to step 7:
164 divided by 80 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 105282.0
The remainder is 4 after subtracting 160 from 164.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 80

Advancing to step 8:
When dividing 48 by 80, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 1052820.0
If we subtract 0 from 48, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
The number 80 fits into 480 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 1052820.6
If we subtract 480 from 480, 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.

Step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1052820.6
Subtract 0 from 0 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:
80 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: 1052820.6
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.

The final outcome is 1052820.6, with a leftover of 0.0.
