524988 divided by 66 
The aim is to understand the frequency of 66 in 524988.

Moving on to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 66

Going ahead to step 2:
The number 66 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (4) from the dividend, attach it to 52 and continue: 524 / 66

Let's proceed to step 3:
66 can be fit into 524 7 times, resulting in a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 62 after subtracting 462 from 524.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 66

Step 4:
When dividing 629 by 66, we get 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 594 from 629 leaves us with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 66

Let's proceed to step 5:
66 can be fit into 358 5 times, resulting in a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 795.0
The remainder is 28 after subtracting 330 from 358.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 66

Going ahead to step 6:
66 goes into 288 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 7954.0
If we subtract 264 from 288, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
66 can be fit into 240 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 7954.3
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7954.36
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
If we divide 240 by 66, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 7954.363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
66 goes into 420 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 7954.3636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
If we divide 240 by 66, we get 3 and a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 7954.36363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 66, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 7954.363636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
66 goes into 240 3 times with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 7954.3636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
66 goes into 420 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 7954.36363636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 7954.36363636, with a leftover of 2.4e-08.
