We look at the division of 105107 by 80 
Our goal is to divide 105107 by 80.

On to step 1:
80 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 80

On to step 2:
The number 80 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 80

Moving on to step 3:
80 can be fit into 105 1 times, resulting in a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 80 away from 105, we end up with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 80

On to step 4:
80 goes into 251 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 240 away from 251, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 80

Let's proceed to step 5:
The number 80 fits into 110 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 131.0
If we subtract 80 from 110, we get 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 80

On to step 6:
The number 80 fits into 307 3 times, leaving a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 1313.0
The remainder is 67 after subtracting 240 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
The number 80 fits into 670 8 times, leaving a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 1313.8
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.

On to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 1313.83
Subtracting 240 from 300 leaves us 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.

Advancing to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 1313.837
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.

Let's proceed to step 10:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1313.8375
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.

Going ahead to step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1313.8375
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.

Going ahead to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1313.8375
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.

The quotient of the division is 1313.8375, and the remainder is 0.0.
