We divide 101003 by 80
We want to divide 101003 by 80.

Let's proceed to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 80

Going ahead to step 2:
10 divided by 80 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 80

Let's proceed to step 3:
80 goes into 101 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 80 from 101, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 80

Going ahead to step 4:
80 goes into 210 2 times with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 160 from 210, we get 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 80

Going ahead to step 5:
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: 126.0
The remainder is 20 after subtracting 480 from 500.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 80

Step 6:
80 can be fit into 203 2 times, resulting in a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 1262.0
If we take 160 away from 203, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
The number 80 fits into 430 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1262.5
Deduct 400 from 430 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 1262.53
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 1262.537
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.

Advancing to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1262.5375
If we subtract 400 from 400, 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.

Going ahead to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1262.5375
If we subtract 0 from 0, 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.

Advancing to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1262.5375
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 quotient of the division is 1262.5375, and the remainder is 0.0.
