Let's divide 81896520 by 633
Our goal is to divide 81896520 by 633.

On to step 1:
The number 633 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 633

Going ahead to step 2:
633 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 633

Moving on to step 3:
633 can be fit into 818 1 times, resulting in a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 185 after subtracting 633 from 818.
Grab the next digit (9) from the dividend, add it to 185, then carry on: 1859 / 633

Step 4:
633 goes into 1859 2 times with a remainder of 593.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1266 from 1859 leaves us with 593.
Bring next digit (6) of the dividend behind the 593 and repeat the process: 5936 / 633

Let's proceed to step 5:
The number 633 fits into 5936 9 times, leaving a remainder of 239.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 5697 away from 5936, we end up with 239.
Include the next digit (5) from the dividend after 239, then repeat: 2395 / 633

Going ahead to step 6:
633 goes into 2395 3 times with a remainder of 496.
Put 3 as the next digit of the answer. 
Result so far: 1293.0
The remainder is 496 after subtracting 1899 from 2395.
Grab the next digit (2) from the dividend, add it to 496, then carry on: 4962 / 633

Step 7:
4962 divided by 633 is 7 with a remainder of 531.
Record the quotient 7 as the next digit in the result. 
Result so far: 12937.0
Subtracting 4431 from 4962 leaves us with 531.
Include the next digit (0) from the dividend after 531, then repeat: 5310 / 633

Let's proceed to step 8:
5310 divided by 633 is 8 with a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 129378.0
Subtracting 5064 from 5310 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 9:
2460 divided by 633 is 3 with a remainder of 561.
The number 3 becomes the next digit in our result. 
Result so far: 129378.3
Subtract 1899 from 2460 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Moving on to step 10:
If we divide 5610 by 633, we get 8 and a remainder of 546.
The next digit of our result is 8. 
Result so far: 129378.38
The remainder is 546 after subtracting 5064 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 11:
5460 divided by 633 is 8 with a remainder of 396.
Put 8 as the next digit of the answer. 
Result so far: 129378.388
If we take 5064 away from 5460, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

After the division, we end up with 129378.388 and a remainder of 0.0396.
