We're dividing 63667093 by 665 
The aim is to understand the frequency of 665 in 63667093.

Advancing to step 1:
If we divide 6 by 665, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 665

Going ahead to step 2:
If we divide 63 by 665, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 665

Moving on to step 3:
If we divide 636 by 665, we get 0 and a remainder of 636.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 636 after subtracting 0 from 636.
Grab the next digit (6) from the dividend, add it to 636, then carry on: 6366 / 665

On to step 4:
6366 divided by 665 is 9 with a remainder of 381.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 5985 away from 6366, we end up with 381.
Include the next digit (7) from the dividend after 381, then repeat: 3817 / 665

Going ahead to step 5:
When dividing 3817 by 665, we get 5 with a remainder of 492.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtracting 3325 from 3817 leaves us with 492.
Include the next digit (0) from the dividend after 492, then repeat: 4920 / 665

Step 6:
When dividing 4920 by 665, we get 7 with a remainder of 265.
Write down 7 as next digit of the result. 
Result so far: 957.0
The remainder is 265 after subtracting 4655 from 4920.
Bring next digit (9) of the dividend behind the 265 and repeat the process: 2659 / 665

Step 7:
When dividing 2659 by 665, we get 3 with a remainder of 664.
Write down 3 as next digit of the result. 
Result so far: 9573.0
Deduct 1995 from 2659 and we're left with 664.
Include the next digit (3) from the dividend after 664, then repeat: 6643 / 665

Advancing to step 8:
When dividing 6643 by 665, we get 9 with a remainder of 658.
Write down 9 as next digit of the result. 
Result so far: 95739.0
Subtract 5985 from 6643 to get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 9:
6580 divided by 665 is 9 with a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 95739.9
Deduct 5985 from 6580 and we're left with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 10:
5950 divided by 665 is 8 with a remainder of 630.
Record the quotient 8 as the next digit in the result. 
Result so far: 95739.98
Deduct 5320 from 5950 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 11:
If we divide 6300 by 665, we get 9 and a remainder of 315.
Write down 9 as next digit of the result. 
Result so far: 95739.989
If we take 5985 away from 6300, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 12:
The number 665 fits into 3150 4 times, leaving a remainder of 490.
Put 4 as the next digit of the answer. 
Result so far: 95739.9894
If we subtract 2660 from 3150, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 13:
4900 divided by 665 is 7 with a remainder of 245.
Put 7 as the next digit of the answer. 
Result so far: 95739.98947
The remainder is 245 after subtracting 4655 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 14:
2450 divided by 665 is 3 with a remainder of 455.
The number 3 becomes the next digit in our result. 
Result so far: 95739.989473
If we take 1995 away from 2450, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 15:
4550 divided by 665 is 6 with a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 95739.9894736
The remainder is 560 after subtracting 3990 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 16:
If we divide 5600 by 665, we get 8 and a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 95739.98947368
Deduct 5320 from 5600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 95739.98947368 with a remainder of 2.8e-07.
