We're dividing 103766 by 80 
Our goal is to divide 103766 by 80.

Let's proceed to step 1:
80 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 80

Moving on to step 2:
10 divided by 80 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 80

Going ahead to step 3:
80 goes into 103 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 23 after subtracting 80 from 103.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 80

On to step 4:
80 goes into 237 2 times with a remainder of 77.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 77 after subtracting 160 from 237.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 80

Going ahead to step 5:
When dividing 776 by 80, we get 9 with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 720 away from 776, we end up with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 80

Advancing to step 6:
566 divided by 80 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 1297.0
Subtracting 560 from 566 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
80 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1297.0
Deduct 0 from 60 and we're left 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.

On to step 8:
600 divided by 80 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 1297.07
If we take 560 away from 600, we end up with 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 9:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1297.075
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.

On to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1297.075
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.

On to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1297.075
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 final outcome is 1297.075, with a leftover of 0.0.
