Let's divide 26579393 by 644
Let's see how many times 644 fits into 26579393.

On to step 1:
644 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 644

Moving on to step 2:
If we divide 26 by 644, we get 0 and a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 644

Step 3:
644 goes into 265 0 times with a remainder of 265.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 265 to get 265.
Bring next digit (7) of the dividend behind the 265 and repeat the process: 2657 / 644

Let's proceed to step 4:
The number 644 fits into 2657 4 times, leaving a remainder of 81.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2576 from 2657 to get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 644

Going ahead to step 5:
819 divided by 644 is 1 with a remainder of 175.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 644 from 819 leaves us with 175.
Include the next digit (3) from the dividend after 175, then repeat: 1753 / 644

Advancing to step 6:
When dividing 1753 by 644, we get 2 with a remainder of 465.
The next digit of our result is 2. 
Result so far: 412.0
If we take 1288 away from 1753, we end up with 465.
Grab the next digit (9) from the dividend, add it to 465, then carry on: 4659 / 644

Moving on to step 7:
The number 644 fits into 4659 7 times, leaving a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 4127.0
Subtract 4508 from 4659 to get 151.
Take the next digit (3) from the dividend and append it to 151, then repeat: 1513 / 644

Moving on to step 8:
644 goes into 1513 2 times with a remainder of 225.
Put 2 as the next digit of the answer. 
Result so far: 41272.0
Subtract 1288 from 1513 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 9:
644 goes into 2250 3 times with a remainder of 318.
The next digit of our result is 3. 
Result so far: 41272.3
Deduct 1932 from 2250 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 10:
If we divide 3180 by 644, we get 4 and a remainder of 604.
Write down 4 as next digit of the result. 
Result so far: 41272.34
Subtracting 2576 from 3180 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 11:
6040 divided by 644 is 9 with a remainder of 244.
Put 9 as the next digit of the answer. 
Result so far: 41272.349
Deduct 5796 from 6040 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 12:
The number 644 fits into 2440 3 times, leaving a remainder of 508.
Record the quotient 3 as the next digit in the result. 
Result so far: 41272.3493
The remainder is 508 after subtracting 1932 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 13:
644 goes into 5080 7 times with a remainder of 572.
Record the quotient 7 as the next digit in the result. 
Result so far: 41272.34937
If we subtract 4508 from 5080, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 14:
5720 divided by 644 is 8 with a remainder of 568.
The number 8 becomes the next digit in our result. 
Result so far: 41272.349378
If we take 5152 away from 5720, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 15:
If we divide 5680 by 644, we get 8 and a remainder of 528.
The number 8 becomes the next digit in our result. 
Result so far: 41272.3493788
The remainder is 528 after subtracting 5152 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Our division results in 41272.3493788 with a remaining 5.28e-06.
