725667 ÷ 27 
The aim is to understand the frequency of 27 in 725667.

Step 1:
If we divide 7 by 27, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 27

On to step 2:
The number 27 fits into 72 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 18 after subtracting 54 from 72.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 27

Advancing to step 3:
The number 27 fits into 185 6 times, leaving a remainder of 23.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 162 from 185 and we're left with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 27

Going ahead to step 4:
If we divide 236 by 27, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 268.0
If we subtract 216 from 236, we get 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 27

Moving on to step 5:
206 divided by 27 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2687.0
Deduct 189 from 206 and we're left with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 27

On to step 6:
When dividing 177 by 27, we get 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 26876.0
Deduct 162 from 177 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 27 fits into 150 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 26876.5
If we subtract 135 from 150, 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.

On to step 8:
The number 27 fits into 150 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 26876.55
If we subtract 135 from 150, 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.

The final result is 26876.55 with a remainder of 0.015.
