Let's divide 12987868 by 633
We're looking to find how many times 633 goes into 12987868.

Advancing to step 1:
When dividing 1 by 633, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 633

Let's proceed to step 2:
633 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 633

On to step 3:
When dividing 129 by 633, we get 0 with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Fetch the next digit (8) from the dividend, attach it to 129 and continue: 1298 / 633

Step 4:
When dividing 1298 by 633, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1266 from 1298 and we're left with 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 633

Advancing to step 5:
633 can be fit into 327 0 times, resulting in a remainder of 327.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 327 leaves us with 327.
Include the next digit (8) from the dividend after 327, then repeat: 3278 / 633

Advancing to step 6:
3278 divided by 633 is 5 with a remainder of 113.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
Subtract 3165 from 3278 to get 113.
Append the next digit (6) from the dividend to 113 and continue with: 1136 / 633

Going ahead to step 7:
633 goes into 1136 1 times with a remainder of 503.
Record the quotient 1 as the next digit in the result. 
Result so far: 2051.0
The remainder is 503 after subtracting 633 from 1136.
Take the next digit (8) from the dividend and append it to 503, then repeat: 5038 / 633

Going ahead to step 8:
When dividing 5038 by 633, we get 7 with a remainder of 607.
The number 7 becomes the next digit in our result. 
Result so far: 20517.0
Subtract 4431 from 5038 to get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 9:
633 can be fit into 6070 9 times, resulting in a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 20517.9
Deduct 5697 from 6070 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Let's proceed to step 10:
If we divide 3730 by 633, we get 5 and a remainder of 565.
Put 5 as the next digit of the answer. 
Result so far: 20517.95
Subtract 3165 from 3730 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 11:
633 can be fit into 5650 8 times, resulting in a remainder of 586.
Record the quotient 8 as the next digit in the result. 
Result so far: 20517.958
If we take 5064 away from 5650, we end up with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 12:
633 can be fit into 5860 9 times, resulting in a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 20517.9589
Subtract 5697 from 5860 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 13:
633 can be fit into 1630 2 times, resulting in a remainder of 364.
Put 2 as the next digit of the answer. 
Result so far: 20517.95892
If we subtract 1266 from 1630, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 14:
633 goes into 3640 5 times with a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 20517.958925
Subtracting 3165 from 3640 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 15:
633 goes into 4750 7 times with a remainder of 319.
Use 7 as the next digit of our solution. 
Result so far: 20517.9589257
Subtract 4431 from 4750 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 16:
The number 633 fits into 3190 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 20517.95892575
Subtract 3165 from 3190 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 20517.95892575 and a remainder of 2.5e-08.
