138411 ÷ 80 
Let's see how many times 80 fits into 138411.

Let's proceed to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 80

On to step 2:
When dividing 13 by 80, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 80

Step 3:
80 goes into 138 1 times with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 80 from 138 and we're left with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 80

Going ahead to step 4:
When dividing 584 by 80, we get 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 24 after subtracting 560 from 584.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 80

Going ahead to step 5:
80 goes into 241 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 173.0
If we subtract 240 from 241, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 80

On to step 6:
When dividing 11 by 80, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 1730.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
If we divide 110 by 80, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1730.1
If we take 80 away from 110, we end up 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.
Put 3 as the next digit of the answer. 
Result so far: 1730.13
The remainder is 60 after subtracting 240 from 300.
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:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1730.137
Subtract 560 from 600 to 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.

Going ahead to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1730.1375
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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1730.1375
The remainder is 0 after subtracting 0 from 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: 1730.1375
If we take 0 away from 0, 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.

The quotient of the division is 1730.1375, and the remainder is 0.0.
