We look at the division of 73613584 by 664 
The aim is to understand the frequency of 664 in 73613584.

Step 1:
664 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 664

Advancing to step 2:
If we divide 73 by 664, we get 0 and a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 664

Going ahead to step 3:
When dividing 736 by 664, we get 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 664 from 736 and we're left with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 664

Going ahead to step 4:
If we divide 721 by 664, we get 1 and a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 664 away from 721, we end up with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 664

Going ahead to step 5:
664 goes into 573 0 times with a remainder of 573.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we subtract 0 from 573, we get 573.
Fetch the next digit (5) from the dividend, attach it to 573 and continue: 5735 / 664

Moving on to step 6:
664 can be fit into 5735 8 times, resulting in a remainder of 423.
Write down 8 as next digit of the result. 
Result so far: 1108.0
Subtract 5312 from 5735 to get 423.
Fetch the next digit (8) from the dividend, attach it to 423 and continue: 4238 / 664

Step 7:
664 can be fit into 4238 6 times, resulting in a remainder of 254.
The next digit of our result is 6. 
Result so far: 11086.0
Subtracting 3984 from 4238 leaves us with 254.
Take the next digit (4) from the dividend and append it to 254, then repeat: 2544 / 664

Advancing to step 8:
If we divide 2544 by 664, we get 3 and a remainder of 552.
Put 3 as the next digit of the answer. 
Result so far: 110863.0
The remainder is 552 after subtracting 1992 from 2544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 9:
664 goes into 5520 8 times with a remainder of 208.
Record the quotient 8 as the next digit in the result. 
Result so far: 110863.8
If we subtract 5312 from 5520, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 10:
2080 divided by 664 is 3 with a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 110863.83
Deduct 1992 from 2080 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
880 divided by 664 is 1 with a remainder of 216.
Write down 1 as next digit of the result. 
Result so far: 110863.831
Subtract 664 from 880 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 12:
664 can be fit into 2160 3 times, resulting in a remainder of 168.
Record the quotient 3 as the next digit in the result. 
Result so far: 110863.8313
The remainder is 168 after subtracting 1992 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 13:
If we divide 1680 by 664, we get 2 and a remainder of 352.
The next digit of our result is 2. 
Result so far: 110863.83132
If we take 1328 away from 1680, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 14:
664 goes into 3520 5 times with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 110863.831325
Subtract 3320 from 3520 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
If we divide 2000 by 664, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 110863.8313253
If we take 1992 away from 2000, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 16:
664 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 110863.8313253
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 110863.8313253 with a remainder of 8e-08.
