583782 ÷ 66 
The aim is to understand the frequency of 66 in 583782.

Moving on to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 66

Moving on to step 2:
The number 66 fits into 58 0 times, leaving a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 66

On to step 3:
If we divide 583 by 66, we get 8 and a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 528 from 583, we get 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 66

Moving on to step 4:
66 goes into 557 8 times with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtract 528 from 557 to get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 66

Step 5:
66 goes into 298 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 884.0
If we subtract 264 from 298, we get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 66

Going ahead to step 6:
If we divide 342 by 66, we get 5 and a remainder of 12.
The next digit of our result is 5. 
Result so far: 8845.0
If we take 330 away from 342, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 8845.1
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
540 divided by 66 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8845.18
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
66 goes into 120 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 8845.181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8845.1818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 8845.18181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8845.181818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
66 goes into 120 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 8845.1818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
If we divide 540 by 66, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8845.18181818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 8845.18181818, with a leftover of 1.2e-08.
