We're dividing 137858 by 90 
We want to divide 137858 by 90.

Advancing to step 1:
90 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 90

Let's proceed to step 2:
If we divide 13 by 90, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 90

Step 3:
137 divided by 90 is 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 90 away from 137, we end up with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 90

Step 4:
90 can be fit into 478 5 times, resulting in a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 450 from 478 to get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 90

Let's proceed to step 5:
285 divided by 90 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 15 after subtracting 270 from 285.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 90

Step 6:
The number 90 fits into 158 1 times, leaving a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 1531.0
Deduct 90 from 158 and we're left with 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:
680 divided by 90 is 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 1531.7
If we take 630 away from 680, we end up 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.

Moving on to step 8:
90 goes into 500 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 1531.75
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.

Let's proceed to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1531.755
If we take 450 away from 500, we end up 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 1531.755, and the remainder is 0.005.
