We're dividing 90725136 by 478 
Our goal is to divide 90725136 by 478.

Moving on to step 1:
9 divided by 478 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 478

Going ahead to step 2:
478 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 478

Step 3:
If we divide 907 by 478, we get 1 and a remainder of 429.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 478 away from 907, we end up with 429.
Include the next digit (2) from the dividend after 429, then repeat: 4292 / 478

Advancing to step 4:
The number 478 fits into 4292 8 times, leaving a remainder of 468.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3824 from 4292 leaves us with 468.
Include the next digit (5) from the dividend after 468, then repeat: 4685 / 478

On to step 5:
The number 478 fits into 4685 9 times, leaving a remainder of 383.
The next digit of our result is 9. 
Result so far: 189.0
If we take 4302 away from 4685, we end up with 383.
Include the next digit (1) from the dividend after 383, then repeat: 3831 / 478

Step 6:
If we divide 3831 by 478, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1898.0
If we subtract 3824 from 3831, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 478

Moving on to step 7:
73 divided by 478 is 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 18980.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 478

Step 8:
If we divide 736 by 478, we get 1 and a remainder of 258.
Put 1 as the next digit of the answer. 
Result so far: 189801.0
Deduct 478 from 736 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 9:
478 goes into 2580 5 times with a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 189801.5
If we take 2390 away from 2580, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
478 goes into 1900 3 times with a remainder of 466.
Use 3 as the next digit of our solution. 
Result so far: 189801.53
Subtract 1434 from 1900 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 11:
478 goes into 4660 9 times with a remainder of 358.
Put 9 as the next digit of the answer. 
Result so far: 189801.539
If we subtract 4302 from 4660, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 12:
478 goes into 3580 7 times with a remainder of 234.
Put 7 as the next digit of the answer. 
Result so far: 189801.5397
Subtracting 3346 from 3580 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 13:
When dividing 2340 by 478, we get 4 with a remainder of 428.
Use 4 as the next digit of our solution. 
Result so far: 189801.53974
If we subtract 1912 from 2340, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 14:
4280 divided by 478 is 8 with a remainder of 456.
Put 8 as the next digit of the answer. 
Result so far: 189801.539748
The remainder is 456 after subtracting 3824 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 15:
4560 divided by 478 is 9 with a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 189801.5397489
Subtracting 4302 from 4560 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 16:
When dividing 2580 by 478, we get 5 with a remainder of 190.
The next digit of our result is 5. 
Result so far: 189801.53974895
If we take 2390 away from 2580, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Our division results in 189801.53974895 with a remaining 1.9e-07.
