26593109 ÷ 900 
We want to figure out the number of times 26593109 can be divided by 900.

Let's proceed to step 1:
When dividing 2 by 900, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 900

Let's proceed to step 2:
If we divide 26 by 900, 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.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 900

Let's proceed to step 3:
900 can be fit into 265 0 times, resulting in a remainder of 265.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 265, we end up with 265.
Grab the next digit (9) from the dividend, add it to 265, then carry on: 2659 / 900

On to step 4:
If we divide 2659 by 900, we get 2 and a remainder of 859.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1800 from 2659 to get 859.
Fetch the next digit (3) from the dividend, attach it to 859 and continue: 8593 / 900

Let's proceed to step 5:
When dividing 8593 by 900, we get 9 with a remainder of 493.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 493 after subtracting 8100 from 8593.
Append the next digit (1) from the dividend to 493 and continue with: 4931 / 900

Going ahead to step 6:
The number 900 fits into 4931 5 times, leaving a remainder of 431.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Deduct 4500 from 4931 and we're left with 431.
Take the next digit (0) from the dividend and append it to 431, then repeat: 4310 / 900

Step 7:
If we divide 4310 by 900, we get 4 and a remainder of 710.
Write down 4 as next digit of the result. 
Result so far: 2954.0
If we subtract 3600 from 4310, we get 710.
Include the next digit (9) from the dividend after 710, then repeat: 7109 / 900

Going ahead to step 8:
If we divide 7109 by 900, we get 7 and a remainder of 809.
Write down 7 as next digit of the result. 
Result so far: 29547.0
Deduct 6300 from 7109 and we're left with 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Moving on to step 9:
900 goes into 8090 8 times with a remainder of 890.
The number 8 becomes the next digit in our result. 
Result so far: 29547.8
Deduct 7200 from 8090 and we're left with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Let's proceed to step 10:
If we divide 8900 by 900, we get 9 and a remainder of 800.
The number 9 becomes the next digit in our result. 
Result so far: 29547.89
Deduct 8100 from 8900 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 11:
The number 900 fits into 8000 8 times, leaving a remainder of 800.
The next digit of our result is 8. 
Result so far: 29547.898
Subtract 7200 from 8000 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 12:
8000 divided by 900 is 8 with a remainder of 800.
The next digit of our result is 8. 
Result so far: 29547.8988
Deduct 7200 from 8000 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 29547.8988, with a leftover of 0.008.
