We're dividing 264138 by 25 
We want to figure out the number of times 264138 can be divided by 25.

Moving on to step 1:
25 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
The remainder is 2 after subtracting 0 from 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 25

On to step 2:
The number 25 fits into 26 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 25 from 26, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 25

Step 3:
If we divide 14 by 25, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 25

Going ahead to step 4:
25 can be fit into 141 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we take 125 away from 141, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 25

Advancing to step 5:
163 divided by 25 is 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 1056.0
Deduct 150 from 163 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 25

On to step 6:
25 can be fit into 138 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 10565.0
If we take 125 away from 138, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
25 can be fit into 130 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10565.5
Deduct 125 from 130 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 10565.52
If we subtract 50 from 50, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10565.52
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10565.52
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10565.52, with a leftover of 0.0.
