28388351 ÷ 636 
We're looking to find how many times 636 goes into 28388351.

On to step 1:
If we divide 2 by 636, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 636

Advancing to step 2:
636 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 636

Going ahead to step 3:
636 can be fit into 283 0 times, resulting in a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 283 to get 283.
Append the next digit (8) from the dividend to 283 and continue with: 2838 / 636

Let's proceed to step 4:
The number 636 fits into 2838 4 times, leaving a remainder of 294.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2544 away from 2838, we end up with 294.
Take the next digit (8) from the dividend and append it to 294, then repeat: 2948 / 636

Moving on to step 5:
If we divide 2948 by 636, we get 4 and a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 2544 from 2948 and we're left with 404.
Bring next digit (3) of the dividend behind the 404 and repeat the process: 4043 / 636

Going ahead to step 6:
636 can be fit into 4043 6 times, resulting in a remainder of 227.
Use 6 as the next digit of our solution. 
Result so far: 446.0
If we take 3816 away from 4043, we end up with 227.
Grab the next digit (5) from the dividend, add it to 227, then carry on: 2275 / 636

Let's proceed to step 7:
If we divide 2275 by 636, we get 3 and a remainder of 367.
The number 3 becomes the next digit in our result. 
Result so far: 4463.0
The remainder is 367 after subtracting 1908 from 2275.
Fetch the next digit (1) from the dividend, attach it to 367 and continue: 3671 / 636

Advancing to step 8:
If we divide 3671 by 636, we get 5 and a remainder of 491.
Write down 5 as next digit of the result. 
Result so far: 44635.0
Deduct 3180 from 3671 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Advancing to step 9:
The number 636 fits into 4910 7 times, leaving a remainder of 458.
Use 7 as the next digit of our solution. 
Result so far: 44635.7
If we subtract 4452 from 4910, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 10:
When dividing 4580 by 636, we get 7 with a remainder of 128.
Use 7 as the next digit of our solution. 
Result so far: 44635.77
If we subtract 4452 from 4580, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 44635.77 with a remainder of 0.128.
