We divide 12839 by 74
We want to divide 12839 by 74.

Let's proceed to step 1:
1 divided by 74 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 74

Advancing to step 2:
12 divided by 74 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 74

Let's proceed to step 3:
When dividing 128 by 74, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 74 from 128 leaves us with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 74

On to step 4:
The number 74 fits into 543 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 518 from 543 and we're left with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 74

Moving on to step 5:
When dividing 259 by 74, we get 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtract 222 from 259 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 6:
370 divided by 74 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 173.5
Subtracting 370 from 370 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.

Moving on to step 7:
74 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 173.5
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.

Moving on to step 8:
0 divided by 74 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 173.5
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.

The final outcome is 173.5, with a leftover of 0.0.
