Let's divide 320315 by 66
The aim is to understand the frequency of 66 in 320315.

On to step 1:
66 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 66

On to step 2:
66 can be fit into 32 0 times, resulting in a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 66

Going ahead to step 3:
If we divide 320 by 66, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 264 from 320 and we're left with 56.
Fetch the next digit (3) from the dividend, attach it to 56 and continue: 563 / 66

Advancing to step 4:
563 divided by 66 is 8 with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 35 after subtracting 528 from 563.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 66

Let's proceed to step 5:
66 can be fit into 351 5 times, resulting in a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 485.0
If we subtract 330 from 351, we get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 66

Moving on to step 6:
215 divided by 66 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 4853.0
Subtract 198 from 215 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
66 goes into 170 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 4853.2
Subtract 132 from 170 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
When dividing 380 by 66, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 4853.25
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 4853.257
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
380 divided by 66 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4853.2575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
If we divide 500 by 66, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 4853.25757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
66 goes into 380 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4853.257575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 4853.2575757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
380 divided by 66 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4853.25757575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 4853.25757575, with a leftover of 5e-08.
