We look at the division of 138718 by 90 
Let's see how many times 90 fits into 138718.

Let's proceed to step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 90

Step 2:
The number 90 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 90

Let's proceed to step 3:
When dividing 138 by 90, we get 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 90 from 138 and we're left with 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 90

Step 4:
487 divided by 90 is 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 450 from 487, we get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 90

On to step 5:
If we divide 371 by 90, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Deduct 360 from 371 and we're left with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 90

Step 6:
When dividing 118 by 90, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1541.0
Subtract 90 from 118 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
If we divide 280 by 90, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 1541.3
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 90 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1541.31
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
90 goes into 100 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1541.311
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 1541.311 with a balance of 0.001.
