266608 ÷ 67 
The aim is to understand the frequency of 67 in 266608.

Advancing to step 1:
2 divided by 67 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 67

Going ahead to step 2:
When dividing 26 by 67, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 67

Moving on to step 3:
67 can be fit into 266 3 times, resulting in a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 201 from 266 leaves us with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 67

On to step 4:
656 divided by 67 is 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 603 from 656 leaves us with 53.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 67

Advancing to step 5:
If we divide 530 by 67, we get 7 and a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 397.0
Deduct 469 from 530 and we're left with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 67

Going ahead to step 6:
The number 67 fits into 618 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 3979.0
If we subtract 603 from 618, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
67 goes into 150 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3979.2
Subtract 134 from 150 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
If we divide 160 by 67, we get 2 and a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 3979.22
If we subtract 134 from 160, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 3979.22 and a remainder of 0.026.
