65150887 ÷ 664 
The aim is to understand the frequency of 664 in 65150887.

Step 1:
6 divided by 664 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 664

On to step 2:
664 goes into 65 0 times with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 664

Going ahead to step 3:
664 can be fit into 651 0 times, resulting in a remainder of 651.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 651 and we're left with 651.
Include the next digit (5) from the dividend after 651, then repeat: 6515 / 664

Moving on to step 4:
6515 divided by 664 is 9 with a remainder of 539.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 5976 from 6515 and we're left with 539.
Take the next digit (0) from the dividend and append it to 539, then repeat: 5390 / 664

Let's proceed to step 5:
664 goes into 5390 8 times with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtract 5312 from 5390 to get 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 664

Advancing to step 6:
788 divided by 664 is 1 with a remainder of 124.
Record the quotient 1 as the next digit in the result. 
Result so far: 981.0
The remainder is 124 after subtracting 664 from 788.
Bring next digit (8) of the dividend behind the 124 and repeat the process: 1248 / 664

Moving on to step 7:
When dividing 1248 by 664, we get 1 with a remainder of 584.
The next digit of our result is 1. 
Result so far: 9811.0
Subtract 664 from 1248 to get 584.
Append the next digit (7) from the dividend to 584 and continue with: 5847 / 664

Going ahead to step 8:
If we divide 5847 by 664, we get 8 and a remainder of 535.
Put 8 as the next digit of the answer. 
Result so far: 98118.0
The remainder is 535 after subtracting 5312 from 5847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 9:
5350 divided by 664 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 98118.8
Deduct 5312 from 5350 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:
If we divide 380 by 664, we get 0 and a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 98118.8
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
664 can be fit into 3800 5 times, resulting in a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 98118.805
Subtracting 3320 from 3800 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
664 goes into 4800 7 times with a remainder of 152.
The number 7 becomes the next digit in our result. 
Result so far: 98118.8057
Deduct 4648 from 4800 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 13:
When dividing 1520 by 664, we get 2 with a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 98118.80572
If we take 1328 away from 1520, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
664 goes into 1920 2 times with a remainder of 592.
Record the quotient 2 as the next digit in the result. 
Result so far: 98118.805722
If we subtract 1328 from 1920, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Our division results in 98118.805722 with a remaining 5.92e-05.
