We divide 139126 by 80
We're looking to find how many times 80 goes into 139126.

Let's proceed to step 1:
1 divided by 80 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 80

Advancing to step 2:
The number 80 fits into 13 0 times, leaving 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.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 80

Moving on to step 3:
When dividing 139 by 80, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 80 from 139 and we're left with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 80

Step 4:
When dividing 591 by 80, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 560 away from 591, we end up with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 80

On to step 5:
80 can be fit into 312 3 times, resulting in a remainder of 72.
The next digit of our result is 3. 
Result so far: 173.0
The remainder is 72 after subtracting 240 from 312.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 80

Going ahead to step 6:
When dividing 726 by 80, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 1739.0
If we subtract 720 from 726, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 80 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1739.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 1739.07
Deduct 560 from 600 and we're left 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.

Going ahead to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1739.075
Deduct 400 from 400 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 10:
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: 1739.075
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.

Moving on to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1739.075
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.

The quotient of the division is 1739.075, and the remainder is 0.0.
