We look at the division of 25412689 by 165 
We want to figure out the number of times 25412689 can be divided by 165.

Going ahead to step 1:
If we divide 2 by 165, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 165

Going ahead to step 2:
If we divide 25 by 165, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 165

Let's proceed to step 3:
165 goes into 254 1 times with a remainder of 89.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 165 from 254 leaves us with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 165

Moving on to step 4:
If we divide 891 by 165, we get 5 and a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 66 after subtracting 825 from 891.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 165

Advancing to step 5:
When dividing 662 by 165, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtract 660 from 662 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 165

Let's proceed to step 6:
165 can be fit into 26 0 times, resulting in a remainder of 26.
The next digit of our result is 0. 
Result so far: 1540.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 165

Going ahead to step 7:
If we divide 268 by 165, we get 1 and a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 15401.0
The remainder is 103 after subtracting 165 from 268.
Append the next digit (9) from the dividend to 103 and continue with: 1039 / 165

Going ahead to step 8:
1039 divided by 165 is 6 with a remainder of 49.
Record the quotient 6 as the next digit in the result. 
Result so far: 154016.0
If we subtract 990 from 1039, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
When dividing 490 by 165, we get 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 154016.2
If we take 330 away from 490, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
1600 divided by 165 is 9 with a remainder of 115.
The number 9 becomes the next digit in our result. 
Result so far: 154016.29
Deduct 1485 from 1600 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 11:
When dividing 1150 by 165, we get 6 with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 154016.296
Subtracting 990 from 1150 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
165 can be fit into 1600 9 times, resulting in a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 154016.2969
Subtracting 1485 from 1600 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 13:
The number 165 fits into 1150 6 times, leaving a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 154016.29696
Deduct 990 from 1150 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
If we divide 1600 by 165, we get 9 and a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 154016.296969
Subtract 1485 from 1600 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 15:
165 can be fit into 1150 6 times, resulting in a remainder of 160.
The next digit of our result is 6. 
Result so far: 154016.2969696
The remainder is 160 after subtracting 990 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
When dividing 1600 by 165, we get 9 with a remainder of 115.
The number 9 becomes the next digit in our result. 
Result so far: 154016.29696969
Subtract 1485 from 1600 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

After the division, we end up with 154016.29696969 and a remainder of 1.15e-07.
