Let's divide 18389458 by 265
We want to divide 18389458 by 265.

Advancing to step 1:
1 divided by 265 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 265

Going ahead to step 2:
18 divided by 265 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 265

On to step 3:
265 goes into 183 0 times with a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 183 to get 183.
Grab the next digit (8) from the dividend, add it to 183, then carry on: 1838 / 265

Advancing to step 4:
If we divide 1838 by 265, we get 6 and a remainder of 248.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 1590 from 1838 to get 248.
Bring next digit (9) of the dividend behind the 248 and repeat the process: 2489 / 265

Moving on to step 5:
265 can be fit into 2489 9 times, resulting in a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 104 after subtracting 2385 from 2489.
Take the next digit (4) from the dividend and append it to 104, then repeat: 1044 / 265

Going ahead to step 6:
When dividing 1044 by 265, we get 3 with a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 693.0
Subtracting 795 from 1044 leaves us with 249.
Append the next digit (5) from the dividend to 249 and continue with: 2495 / 265

Going ahead to step 7:
265 goes into 2495 9 times with a remainder of 110.
The next digit of our result is 9. 
Result so far: 6939.0
If we subtract 2385 from 2495, we get 110.
Take the next digit (8) from the dividend and append it to 110, then repeat: 1108 / 265

Step 8:
265 goes into 1108 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 69394.0
Subtract 1060 from 1108 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 265, we get 1 and a remainder of 215.
Write down 1 as next digit of the result. 
Result so far: 69394.1
Deduct 265 from 480 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 10:
The number 265 fits into 2150 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 69394.18
Deduct 2120 from 2150 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
When dividing 300 by 265, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 69394.181
The remainder is 35 after subtracting 265 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 265 fits into 350 1 times, leaving a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 69394.1811
If we take 265 away from 350, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 69394.1811 with a remainder of 0.00085.
