138740 divided by 15 
We're looking to find how many times 15 goes into 138740.

Moving on to step 1:
15 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 15

Going ahead to step 2:
15 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 15

Moving on to step 3:
138 divided by 15 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 135 from 138, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 15

Advancing to step 4:
If we divide 37 by 15, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Deduct 30 from 37 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 15

Advancing to step 5:
When dividing 74 by 15, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 924.0
The remainder is 14 after subtracting 60 from 74.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 15

Let's proceed to step 6:
If we divide 140 by 15, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 9249.0
Subtract 135 from 140 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 9249.3
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.

Moving on to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 9249.33
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 9249.33 with a balance of 0.005.
