We divide 248534 by 66
The aim is to understand the frequency of 66 in 248534.

Moving on to step 1:
2 divided by 66 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.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 66

Step 2:
When dividing 24 by 66, we get 0 with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 66

Moving on to step 3:
66 can be fit into 248 3 times, resulting in a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 50 after subtracting 198 from 248.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 66

Advancing to step 4:
If we divide 505 by 66, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 462 away from 505, we end up with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 66

On to step 5:
If we divide 433 by 66, we get 6 and a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 376.0
Deduct 396 from 433 and we're left with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 66

Going ahead to step 6:
66 goes into 374 5 times with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 3765.0
If we take 330 away from 374, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
The number 66 fits into 440 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 3765.6
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
440 divided by 66 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3765.66
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 3765.66, with a leftover of 0.044.
