We divide 65373659 by 665
The aim is to understand the frequency of 665 in 65373659.

Moving on to step 1:
The number 665 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 665

Step 2:
665 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 665

Moving on to step 3:
665 can be fit into 653 0 times, resulting in a remainder of 653.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 653, we end up with 653.
Take the next digit (7) from the dividend and append it to 653, then repeat: 6537 / 665

On to step 4:
665 goes into 6537 9 times with a remainder of 552.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 5985 from 6537 leaves us with 552.
Take the next digit (3) from the dividend and append it to 552, then repeat: 5523 / 665

Moving on to step 5:
When dividing 5523 by 665, we get 8 with a remainder of 203.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we subtract 5320 from 5523, we get 203.
Include the next digit (6) from the dividend after 203, then repeat: 2036 / 665

Let's proceed to step 6:
665 goes into 2036 3 times with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 983.0
Deduct 1995 from 2036 and we're left with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 665

On to step 7:
415 divided by 665 is 0 with a remainder of 415.
The number 0 becomes the next digit in our result. 
Result so far: 9830.0
Subtracting 0 from 415 leaves us with 415.
Take the next digit (9) from the dividend and append it to 415, then repeat: 4159 / 665

Let's proceed to step 8:
The number 665 fits into 4159 6 times, leaving a remainder of 169.
The next digit of our result is 6. 
Result so far: 98306.0
Subtracting 3990 from 4159 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 9:
1690 divided by 665 is 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 98306.2
If we subtract 1330 from 1690, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
665 can be fit into 3600 5 times, resulting in a remainder of 275.
The next digit of our result is 5. 
Result so far: 98306.25
Subtract 3325 from 3600 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 11:
The number 665 fits into 2750 4 times, leaving a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 98306.254
Deduct 2660 from 2750 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
When dividing 900 by 665, we get 1 with a remainder of 235.
The next digit of our result is 1. 
Result so far: 98306.2541
Subtract 665 from 900 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 13:
665 goes into 2350 3 times with a remainder of 355.
Write down 3 as next digit of the result. 
Result so far: 98306.25413
If we take 1995 away from 2350, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 14:
The number 665 fits into 3550 5 times, leaving a remainder of 225.
The next digit of our result is 5. 
Result so far: 98306.254135
Subtracting 3325 from 3550 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 15:
The number 665 fits into 2250 3 times, leaving a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 98306.2541353
Subtract 1995 from 2250 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 16:
If we divide 2550 by 665, we get 3 and a remainder of 555.
Use 3 as the next digit of our solution. 
Result so far: 98306.25413533
The remainder is 555 after subtracting 1995 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The final outcome is 98306.25413533, with a leftover of 5.55e-07.
