Let's divide 41087027 by 644
We're looking to find how many times 644 goes into 41087027.

Advancing to step 1:
644 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 644

Step 2:
644 can be fit into 41 0 times, resulting in a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 644

Moving on to step 3:
644 goes into 410 0 times with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 410 after subtracting 0 from 410.
Bring next digit (8) of the dividend behind the 410 and repeat the process: 4108 / 644

Going ahead to step 4:
4108 divided by 644 is 6 with a remainder of 244.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 3864 away from 4108, we end up with 244.
Include the next digit (7) from the dividend after 244, then repeat: 2447 / 644

Moving on to step 5:
2447 divided by 644 is 3 with a remainder of 515.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Deduct 1932 from 2447 and we're left with 515.
Grab the next digit (0) from the dividend, add it to 515, then carry on: 5150 / 644

Going ahead to step 6:
644 goes into 5150 7 times with a remainder of 642.
The next digit of our result is 7. 
Result so far: 637.0
If we take 4508 away from 5150, we end up with 642.
Bring next digit (2) of the dividend behind the 642 and repeat the process: 6422 / 644

Advancing to step 7:
6422 divided by 644 is 9 with a remainder of 626.
Put 9 as the next digit of the answer. 
Result so far: 6379.0
If we subtract 5796 from 6422, we get 626.
Grab the next digit (7) from the dividend, add it to 626, then carry on: 6267 / 644

Let's proceed to step 8:
644 goes into 6267 9 times with a remainder of 471.
The number 9 becomes the next digit in our result. 
Result so far: 63799.0
The remainder is 471 after subtracting 5796 from 6267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 9:
644 can be fit into 4710 7 times, resulting in a remainder of 202.
Put 7 as the next digit of the answer. 
Result so far: 63799.7
If we subtract 4508 from 4710, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
The number 644 fits into 2020 3 times, leaving a remainder of 88.
The next digit of our result is 3. 
Result so far: 63799.73
Subtract 1932 from 2020 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.

Advancing to step 11:
The number 644 fits into 880 1 times, leaving a remainder of 236.
Put 1 as the next digit of the answer. 
Result so far: 63799.731
Subtracting 644 from 880 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 12:
The number 644 fits into 2360 3 times, leaving a remainder of 428.
The number 3 becomes the next digit in our result. 
Result so far: 63799.7313
Subtracting 1932 from 2360 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 13:
The number 644 fits into 4280 6 times, leaving a remainder of 416.
The number 6 becomes the next digit in our result. 
Result so far: 63799.73136
The remainder is 416 after subtracting 3864 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 14:
644 can be fit into 4160 6 times, resulting in a remainder of 296.
Write down 6 as next digit of the result. 
Result so far: 63799.731366
Subtract 3864 from 4160 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 63799.731366 with a remainder of 2.96e-05.
