41866292 ÷ 644 
We want to figure out the number of times 41866292 can be divided by 644.

Let's proceed to step 1:
644 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 644

Step 2:
When dividing 41 by 644, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 644

Moving on to step 3:
644 goes into 418 0 times with a remainder of 418.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 418 after subtracting 0 from 418.
Append the next digit (6) from the dividend to 418 and continue with: 4186 / 644

Going ahead to step 4:
644 can be fit into 4186 6 times, resulting in a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3864 from 4186 and we're left with 322.
Take the next digit (6) from the dividend and append it to 322, then repeat: 3226 / 644

Let's proceed to step 5:
644 goes into 3226 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Deduct 3220 from 3226 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 644

On to step 6:
When dividing 62 by 644, we get 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 650.0
Subtracting 0 from 62 leaves us with 62.
Grab the next digit (9) from the dividend, add it to 62, then carry on: 629 / 644

Let's proceed to step 7:
If we divide 629 by 644, we get 0 and a remainder of 629.
Use 0 as the next digit of our solution. 
Result so far: 6500.0
If we subtract 0 from 629, we get 629.
Include the next digit (2) from the dividend after 629, then repeat: 6292 / 644

Moving on to step 8:
644 can be fit into 6292 9 times, resulting in a remainder of 496.
Use 9 as the next digit of our solution. 
Result so far: 65009.0
Subtracting 5796 from 6292 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 9:
The number 644 fits into 4960 7 times, leaving a remainder of 452.
Write down 7 as next digit of the result. 
Result so far: 65009.7
Deduct 4508 from 4960 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
When dividing 4520 by 644, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 65009.77
The remainder is 12 after subtracting 4508 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 65009.77 and a remainder of 0.012.
