We divide 648895 by 66
The aim is to understand the frequency of 66 in 648895.

Going ahead to step 1:
When dividing 6 by 66, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 66

Going ahead to step 2:
66 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 66

Going ahead to step 3:
The number 66 fits into 648 9 times, leaving a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 594 from 648 and we're left with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 66

Let's proceed to step 4:
If we divide 548 by 66, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtracting 528 from 548 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 66

Advancing to step 5:
When dividing 209 by 66, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 983.0
Deduct 198 from 209 and we're left with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 66

Moving on to step 6:
When dividing 115 by 66, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 9831.0
If we take 66 away from 115, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
If we divide 490 by 66, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 9831.7
If we subtract 462 from 490, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 9831.74
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
If we divide 160 by 66, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 9831.742
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 9831.7424
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
66 goes into 160 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 9831.74242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
66 can be fit into 280 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9831.742424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
66 goes into 160 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 9831.7424242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 9831.74242424
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 9831.74242424 with a remaining 1.6e-08.
