100359 divided by 80 
We want to divide 100359 by 80.

Advancing to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 80

Advancing to step 2:
The number 80 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 80

Step 3:
When dividing 100 by 80, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 80 from 100 and we're left with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 80

Moving on to step 4:
When dividing 203 by 80, we get 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 160 away from 203, we end up with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 80

Step 5:
If we divide 435 by 80, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 400 from 435 leaves us with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 80

Advancing to step 6:
The number 80 fits into 359 4 times, leaving a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 1254.0
The remainder is 39 after subtracting 320 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
80 can be fit into 390 4 times, resulting in a remainder of 70.
The next digit of our result is 4. 
Result so far: 1254.4
If we subtract 320 from 390, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
80 goes into 700 8 times with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 1254.48
The remainder is 60 after subtracting 640 from 700.
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:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The next digit of our result is 7. 
Result so far: 1254.487
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1254.4875
Deduct 400 from 400 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.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1254.4875
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.

Moving on to step 12:
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: 1254.4875
Subtracting 0 from 0 leaves us 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.

Our division results in 1254.4875 with a remaining 0.0.
