137169 ÷ 80 
We want to figure out the number of times 137169 can be divided by 80.

Advancing to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 80

Going ahead to step 2:
13 divided by 80 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 80

Moving on to step 3:
137 divided by 80 is 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 80 from 137, we get 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 80

On to step 4:
When dividing 571 by 80, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 560 from 571 leaves us with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 80

Going ahead to step 5:
80 goes into 116 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 171.0
The remainder is 36 after subtracting 80 from 116.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 80

Moving on to step 6:
If we divide 369 by 80, we get 4 and a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 1714.0
Subtract 320 from 369 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
The number 80 fits into 490 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 1714.6
If we take 480 away from 490, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 80 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1714.61
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1714.612
Subtracting 160 from 200 leaves us 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 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1714.6125
The remainder is 0 after subtracting 400 from 400.
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.
The next digit of our result is 0. 
Result so far: 1714.6125
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.

Going ahead to step 12:
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: 1714.6125
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.

After the division, we end up with 1714.6125 and a remainder of 0.0.
