We're dividing 139842 by 71 
We want to figure out the number of times 139842 can be divided by 71.

Step 1:
71 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 71

Let's proceed to step 2:
13 divided by 71 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 71

Moving on to step 3:
The number 71 fits into 139 1 times, leaving a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 68 after subtracting 71 from 139.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 71

Advancing to step 4:
71 can be fit into 688 9 times, resulting in a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 49 after subtracting 639 from 688.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 71

Step 5:
494 divided by 71 is 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 196.0
Subtract 426 from 494 to get 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 71

Moving on to step 6:
If we divide 682 by 71, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 1969.0
Subtract 639 from 682 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
71 can be fit into 430 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1969.6
Subtract 426 from 430 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 71 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1969.6
If we subtract 0 from 40, we get 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:
71 goes into 400 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1969.605
Subtract 355 from 400 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
If we divide 450 by 71, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1969.6056
Deduct 426 from 450 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 71 fits into 240 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 1969.60563
The remainder is 27 after subtracting 213 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
71 goes into 270 3 times with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 1969.605633
Subtracting 213 from 270 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 1969.605633 with a remaining 5.7e-06.
