We're dividing 90174036 by 491 
We want to divide 90174036 by 491.

Advancing to step 1:
491 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 491

Moving on to step 2:
491 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 491

On to step 3:
When dividing 901 by 491, we get 1 with a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 410 after subtracting 491 from 901.
Take the next digit (7) from the dividend and append it to 410, then repeat: 4107 / 491

On to step 4:
When dividing 4107 by 491, we get 8 with a remainder of 179.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3928 from 4107 to get 179.
Fetch the next digit (4) from the dividend, attach it to 179 and continue: 1794 / 491

On to step 5:
The number 491 fits into 1794 3 times, leaving a remainder of 321.
The next digit of our result is 3. 
Result so far: 183.0
The remainder is 321 after subtracting 1473 from 1794.
Fetch the next digit (0) from the dividend, attach it to 321 and continue: 3210 / 491

Going ahead to step 6:
When dividing 3210 by 491, we get 6 with a remainder of 264.
The next digit of our result is 6. 
Result so far: 1836.0
Subtracting 2946 from 3210 leaves us with 264.
Take the next digit (3) from the dividend and append it to 264, then repeat: 2643 / 491

Advancing to step 7:
When dividing 2643 by 491, we get 5 with a remainder of 188.
The next digit of our result is 5. 
Result so far: 18365.0
Deduct 2455 from 2643 and we're left with 188.
Fetch the next digit (6) from the dividend, attach it to 188 and continue: 1886 / 491

On to step 8:
491 can be fit into 1886 3 times, resulting in a remainder of 413.
The number 3 becomes the next digit in our result. 
Result so far: 183653.0
Deduct 1473 from 1886 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Let's proceed to step 9:
If we divide 4130 by 491, we get 8 and a remainder of 202.
Use 8 as the next digit of our solution. 
Result so far: 183653.8
Deduct 3928 from 4130 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
The number 491 fits into 2020 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 183653.84
If we subtract 1964 from 2020, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
491 goes into 560 1 times with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 183653.841
The remainder is 69 after subtracting 491 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
If we divide 690 by 491, we get 1 and a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 183653.8411
Deduct 491 from 690 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 183653.8411 and a remainder of 0.00199.
