We're dividing 80395618 by 633 
We want to figure out the number of times 80395618 can be divided by 633.

Step 1:
633 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 633

Advancing to step 2:
If we divide 80 by 633, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 633

Moving on to step 3:
633 goes into 803 1 times with a remainder of 170.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 633 from 803 to get 170.
Grab the next digit (9) from the dividend, add it to 170, then carry on: 1709 / 633

Let's proceed to step 4:
The number 633 fits into 1709 2 times, leaving a remainder of 443.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1266 from 1709, we get 443.
Append the next digit (5) from the dividend to 443 and continue with: 4435 / 633

Going ahead to step 5:
633 goes into 4435 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 127.0
The remainder is 4 after subtracting 4431 from 4435.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 633

Going ahead to step 6:
46 divided by 633 is 0 with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 1270.0
Subtracting 0 from 46 leaves us with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 633

On to step 7:
633 can be fit into 461 0 times, resulting in a remainder of 461.
Put 0 as the next digit of the answer. 
Result so far: 12700.0
Subtract 0 from 461 to get 461.
Grab the next digit (8) from the dividend, add it to 461, then carry on: 4618 / 633

Going ahead to step 8:
633 can be fit into 4618 7 times, resulting in a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 127007.0
The remainder is 187 after subtracting 4431 from 4618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
The number 633 fits into 1870 2 times, leaving a remainder of 604.
Record the quotient 2 as the next digit in the result. 
Result so far: 127007.2
Deduct 1266 from 1870 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 10:
If we divide 6040 by 633, we get 9 and a remainder of 343.
Use 9 as the next digit of our solution. 
Result so far: 127007.29
Subtracting 5697 from 6040 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 11:
633 can be fit into 3430 5 times, resulting in a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 127007.295
Deduct 3165 from 3430 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 12:
When dividing 2650 by 633, we get 4 with a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 127007.2954
Subtract 2532 from 2650 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 13:
If we divide 1180 by 633, we get 1 and a remainder of 547.
Record the quotient 1 as the next digit in the result. 
Result so far: 127007.29541
Subtract 633 from 1180 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

On to step 14:
633 can be fit into 5470 8 times, resulting in a remainder of 406.
Put 8 as the next digit of the answer. 
Result so far: 127007.295418
Subtracting 5064 from 5470 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 15:
The number 633 fits into 4060 6 times, leaving a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 127007.2954186
Subtracting 3798 from 4060 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 16:
633 can be fit into 2620 4 times, resulting in a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 127007.29541864
Subtract 2532 from 2620 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 127007.29541864 with a remainder of 8.8e-08.
