We look at the division of 845229 by 80 
We want to figure out the number of times 845229 can be divided by 80.

On to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 80

Advancing to step 2:
80 goes into 84 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 84 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 80

Going ahead to step 3:
80 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 80

Going ahead to step 4:
80 can be fit into 452 5 times, resulting in a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we subtract 400 from 452, we get 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 80

Advancing to step 5:
The number 80 fits into 522 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 1056.0
Subtracting 480 from 522 leaves us with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 80

On to step 6:
The number 80 fits into 429 5 times, leaving a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 10565.0
Subtract 400 from 429 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
80 goes into 290 3 times with a remainder of 50.
The next digit of our result is 3. 
Result so far: 10565.3
The remainder is 50 after subtracting 240 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 10565.36
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 80 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 10565.362
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10565.3625
If we take 400 away from 400, 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.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10565.3625
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.

Step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10565.3625
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.

After the division, we end up with 10565.3625 and a remainder of 0.0.
