138758 ÷ 90 
Let's see how many times 90 fits into 138758.

Let's proceed to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 90

Advancing to 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
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 90

Moving on to step 3:
90 goes into 138 1 times with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 90 from 138 to get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 90

Step 4:
90 can be fit into 487 5 times, resulting in a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 450 away from 487, we end up with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 90

Let's proceed to step 5:
The number 90 fits into 375 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 154.0
The remainder is 15 after subtracting 360 from 375.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 90

Let's proceed to step 6:
When dividing 158 by 90, we get 1 with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 1541.0
Subtract 90 from 158 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 7:
The number 90 fits into 680 7 times, leaving a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 1541.7
The remainder is 50 after subtracting 630 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 90, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 1541.75
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
90 can be fit into 500 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 1541.755
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 1541.755, and the remainder is 0.005.
