We look at the division of 873913 by 90 
We want to divide 873913 by 90.

Advancing to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 90

Going ahead to step 2:
When dividing 87 by 90, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 90

Going ahead to step 3:
873 divided by 90 is 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 810 from 873, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 90

Step 4:
90 can be fit into 639 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 630 from 639, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 90

Moving on to step 5:
90 goes into 91 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 971.0
The remainder is 1 after subtracting 90 from 91.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 90

Moving on to step 6:
If we divide 13 by 90, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 9710.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
90 goes into 130 1 times with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 9710.1
Deduct 90 from 130 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 9710.14
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
90 can be fit into 400 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 9710.144
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 9710.144 with a remaining 0.004.
