We look at the division of 26613629 by 644 
We're looking to find how many times 644 goes into 26613629.

Let's proceed to step 1:
644 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 644

Step 2:
644 can be fit into 26 0 times, resulting in a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 644

Step 3:
The number 644 fits into 266 0 times, leaving a remainder of 266.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 266 to get 266.
Grab the next digit (1) from the dividend, add it to 266, then carry on: 2661 / 644

Going ahead to step 4:
2661 divided by 644 is 4 with a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 2576 from 2661 leaves us with 85.
Append the next digit (3) from the dividend to 85 and continue with: 853 / 644

Moving on to step 5:
The number 644 fits into 853 1 times, leaving a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 644 from 853, we get 209.
Take the next digit (6) from the dividend and append it to 209, then repeat: 2096 / 644

Advancing to step 6:
644 can be fit into 2096 3 times, resulting in a remainder of 164.
Put 3 as the next digit of the answer. 
Result so far: 413.0
The remainder is 164 after subtracting 1932 from 2096.
Include the next digit (2) from the dividend after 164, then repeat: 1642 / 644

Going ahead to step 7:
1642 divided by 644 is 2 with a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 4132.0
Deduct 1288 from 1642 and we're left with 354.
Bring next digit (9) of the dividend behind the 354 and repeat the process: 3549 / 644

On to step 8:
The number 644 fits into 3549 5 times, leaving a remainder of 329.
The next digit of our result is 5. 
Result so far: 41325.0
Subtracting 3220 from 3549 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
The number 644 fits into 3290 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 41325.5
Subtract 3220 from 3290 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
When dividing 700 by 644, we get 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 41325.51
Deduct 644 from 700 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
560 divided by 644 is 0 with a remainder of 560.
The next digit of our result is 0. 
Result so far: 41325.51
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 12:
644 can be fit into 5600 8 times, resulting in a remainder of 448.
The next digit of our result is 8. 
Result so far: 41325.5108
If we take 5152 away from 5600, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 13:
The number 644 fits into 4480 6 times, leaving a remainder of 616.
The number 6 becomes the next digit in our result. 
Result so far: 41325.51086
If we take 3864 away from 4480, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 14:
The number 644 fits into 6160 9 times, leaving a remainder of 364.
Record the quotient 9 as the next digit in the result. 
Result so far: 41325.510869
The remainder is 364 after subtracting 5796 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 15:
3640 divided by 644 is 5 with a remainder of 420.
Put 5 as the next digit of the answer. 
Result so far: 41325.5108695
Deduct 3220 from 3640 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 16:
4200 divided by 644 is 6 with a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 41325.51086956
If we take 3864 away from 4200, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

In conclusion, the division gives 41325.51086956 with a balance of 3.36e-07.
