We look at the division of 26081485 by 644 
Our goal is to divide 26081485 by 644.

Going ahead to step 1:
When dividing 2 by 644, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 644

Moving on to step 2:
26 divided by 644 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 644

Let's proceed to step 3:
260 divided by 644 is 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 260 to get 260.
Bring next digit (8) of the dividend behind the 260 and repeat the process: 2608 / 644

Let's proceed to step 4:
644 can be fit into 2608 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 32 after subtracting 2576 from 2608.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 644

Moving on to step 5:
When dividing 321 by 644, we get 0 with a remainder of 321.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 321 to get 321.
Append the next digit (4) from the dividend to 321 and continue with: 3214 / 644

On to step 6:
644 goes into 3214 4 times with a remainder of 638.
Put 4 as the next digit of the answer. 
Result so far: 404.0
The remainder is 638 after subtracting 2576 from 3214.
Append the next digit (8) from the dividend to 638 and continue with: 6388 / 644

On to step 7:
644 can be fit into 6388 9 times, resulting in a remainder of 592.
Put 9 as the next digit of the answer. 
Result so far: 4049.0
The remainder is 592 after subtracting 5796 from 6388.
Append the next digit (5) from the dividend to 592 and continue with: 5925 / 644

Advancing to step 8:
5925 divided by 644 is 9 with a remainder of 129.
The next digit of our result is 9. 
Result so far: 40499.0
Subtracting 5796 from 5925 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 9:
If we divide 1290 by 644, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 40499.2
Subtracting 1288 from 1290 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 644, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 40499.2
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 644, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 40499.2
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 40499.2 with a remainder of 0.02.
