We divide 754871 by 90
Our goal is to divide 754871 by 90.

Going ahead to step 1:
7 divided by 90 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 90

On to step 2:
90 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 90

On to step 3:
When dividing 754 by 90, we get 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 720 from 754 leaves us with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 90

Let's proceed to step 4:
90 can be fit into 348 3 times, resulting in a remainder of 78.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 270 from 348 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 90

On to step 5:
787 divided by 90 is 8 with a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 838.0
If we subtract 720 from 787, we get 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 90

On to step 6:
When dividing 671 by 90, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 8387.0
If we subtract 630 from 671, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
If we divide 410 by 90, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 8387.4
Deduct 360 from 410 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 8:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 8387.45
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.

Advancing 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: 8387.455
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 8387.455, with a leftover of 0.005.
