We divide 617660 by 66
The aim is to understand the frequency of 66 in 617660.

Let's proceed to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 66

Step 2:
When dividing 61 by 66, we get 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 66

Let's proceed to step 3:
If we divide 617 by 66, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 594 away from 617, we end up with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 66

Moving on to step 4:
If we divide 236 by 66, we get 3 and a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 198 from 236, we get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 66

Step 5:
The number 66 fits into 386 5 times, leaving a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 935.0
Deduct 330 from 386 and we're left with 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 66

Moving on to step 6:
66 can be fit into 560 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 9358.0
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
66 goes into 320 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 9358.4
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
When dividing 560 by 66, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 9358.48
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
The number 66 fits into 320 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 9358.484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
560 divided by 66 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 9358.4848
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
320 divided by 66 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 9358.48484
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 9358.484848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
When dividing 320 by 66, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 9358.4848484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
When dividing 560 by 66, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 9358.48484848
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 9358.48484848, with a leftover of 3.2e-08.
