Let's divide 138485 by 80
We want to divide 138485 by 80.

Going ahead to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 80

Step 2:
80 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 80

Step 3:
The number 80 fits into 138 1 times, leaving a remainder of 58.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 138, we get 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 80

On to step 4:
80 goes into 584 7 times with a remainder of 24.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 560 from 584 leaves us with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 80

Step 5:
248 divided by 80 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 173.0
If we subtract 240 from 248, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 80

Step 6:
80 can be fit into 85 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1731.0
Subtracting 80 from 85 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
80 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 1731.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1731.06
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
80 goes into 200 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1731.062
If we take 160 away from 200, 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.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1731.0625
Subtracting 400 from 400 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.

Going ahead to step 11:
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: 1731.0625
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.

Going ahead to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1731.0625
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.

After the division, we end up with 1731.0625 and a remainder of 0.0.
