We're dividing 41517964 by 639 
We're looking to find how many times 639 goes into 41517964.

Step 1:
639 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 639

Step 2:
If we divide 41 by 639, we get 0 and a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 639

Going ahead to step 3:
If we divide 415 by 639, we get 0 and a remainder of 415.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 415 to get 415.
Include the next digit (1) from the dividend after 415, then repeat: 4151 / 639

Let's proceed to step 4:
639 can be fit into 4151 6 times, resulting in a remainder of 317.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 3834 from 4151 and we're left with 317.
Bring next digit (7) of the dividend behind the 317 and repeat the process: 3177 / 639

Let's proceed to step 5:
The number 639 fits into 3177 4 times, leaving a remainder of 621.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtract 2556 from 3177 to get 621.
Include the next digit (9) from the dividend after 621, then repeat: 6219 / 639

Moving on to step 6:
The number 639 fits into 6219 9 times, leaving a remainder of 468.
Record the quotient 9 as the next digit in the result. 
Result so far: 649.0
Deduct 5751 from 6219 and we're left with 468.
Fetch the next digit (6) from the dividend, attach it to 468 and continue: 4686 / 639

Moving on to step 7:
4686 divided by 639 is 7 with a remainder of 213.
Use 7 as the next digit of our solution. 
Result so far: 6497.0
If we take 4473 away from 4686, we end up with 213.
Append the next digit (4) from the dividend to 213 and continue with: 2134 / 639

On to step 8:
When dividing 2134 by 639, we get 3 with a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 64973.0
If we take 1917 away from 2134, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 9:
When dividing 2170 by 639, we get 3 with a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 64973.3
Subtracting 1917 from 2170 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 10:
639 goes into 2530 3 times with a remainder of 613.
Write down 3 as next digit of the result. 
Result so far: 64973.33
Subtracting 1917 from 2530 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

After the division, we end up with 64973.33 and a remainder of 0.613.
