Let's divide 140939 by 15
Let's see how many times 15 fits into 140939.

Advancing to step 1:
1 divided by 15 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 15

On to step 2:
14 divided by 15 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 15

Advancing to step 3:
If we divide 140 by 15, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 135 from 140 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 15

Going ahead to step 4:
15 goes into 59 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 93.0
Deduct 45 from 59 and we're left with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 15

Advancing to step 5:
The number 15 fits into 143 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 939.0
If we subtract 135 from 143, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 15

On to step 6:
89 divided by 15 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 9395.0
If we subtract 75 from 89, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
15 goes into 140 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 9395.9
Subtracting 135 from 140 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 9395.93
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 9395.933
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 9395.933 with a remaining 0.0005.
