644602 ÷ 41 
We want to figure out the number of times 644602 can be divided by 41.

Step 1:
The number 41 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 41

Going ahead to step 2:
If we divide 64 by 41, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 23 after subtracting 41 from 64.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 41

Moving on to step 3:
If we divide 234 by 41, we get 5 and a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 29 after subtracting 205 from 234.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 41

Going ahead to step 4:
41 goes into 296 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Subtract 287 from 296 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 41

Going ahead to step 5:
If we divide 90 by 41, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1572.0
If we take 82 away from 90, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 41

Step 6:
If we divide 82 by 41, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 15722.0
The remainder is 0 after subtracting 82 from 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 41 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15722.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 41 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15722.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15722.0, and the remainder is 0.0.
