138744 divided by 79 
Our goal is to divide 138744 by 79.

Step 1:
79 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 79

Moving on to step 2:
79 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 79

On to step 3:
When dividing 138 by 79, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 79 from 138, we get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 79

On to step 4:
597 divided by 79 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 553 from 597 leaves us with 44.
Grab the next digit (4) from the dividend, add it to 44, then carry on: 444 / 79

Let's proceed to step 5:
444 divided by 79 is 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
Deduct 395 from 444 and we're left with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 79

Advancing to step 6:
The number 79 fits into 494 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1756.0
If we take 474 away from 494, we end up 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.

Moving on to step 7:
79 goes into 200 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 1756.2
If we subtract 158 from 200, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1756.25
Subtracting 395 from 420 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
79 goes into 250 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 1756.253
Deduct 237 from 250 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
The number 79 fits into 130 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1756.2531
Subtracting 79 from 130 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 11:
If we divide 510 by 79, we get 6 and a remainder of 36.
The next digit of our result is 6. 
Result so far: 1756.25316
Subtracting 474 from 510 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
360 divided by 79 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 1756.253164
If we subtract 316 from 360, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 79, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1756.2531645
If we take 395 away from 440, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
79 can be fit into 450 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1756.25316455
If we subtract 395 from 450, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 1756.25316455 with a remaining 5.5e-08.
