We're dividing 66278678 by 265 
The aim is to understand the frequency of 265 in 66278678.

Step 1:
265 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 265

Let's proceed to step 2:
When dividing 66 by 265, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (2) from the dividend and append it to 66, then repeat: 662 / 265

Going ahead to step 3:
When dividing 662 by 265, we get 2 with a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 530 from 662, we get 132.
Grab the next digit (7) from the dividend, add it to 132, then carry on: 1327 / 265

Going ahead to step 4:
If we divide 1327 by 265, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 1325 from 1327, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 265

Let's proceed to step 5:
265 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtract 0 from 28 to get 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 265

On to step 6:
If we divide 286 by 265, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 2501.0
If we subtract 265 from 286, we get 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 265

Going ahead to step 7:
The number 265 fits into 217 0 times, leaving a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 25010.0
Deduct 0 from 217 and we're left with 217.
Append the next digit (8) from the dividend to 217 and continue with: 2178 / 265

Let's proceed to step 8:
2178 divided by 265 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 250108.0
Subtract 2120 from 2178 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
580 divided by 265 is 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 250108.2
Subtracting 530 from 580 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 265, we get 1 with a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 250108.21
The remainder is 235 after subtracting 265 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 11:
2350 divided by 265 is 8 with a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 250108.218
Subtracting 2120 from 2350 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
2300 divided by 265 is 8 with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 250108.2188
The remainder is 180 after subtracting 2120 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 250108.2188, and the remainder is 0.0018.
