We're dividing 63578751 by 665 
The aim is to understand the frequency of 665 in 63578751.

Step 1:
6 divided by 665 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 665

On to step 2:
The number 665 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 665

Moving on to step 3:
When dividing 635 by 665, we get 0 with a remainder of 635.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 635, we end up with 635.
Fetch the next digit (7) from the dividend, attach it to 635 and continue: 6357 / 665

Let's proceed to step 4:
If we divide 6357 by 665, we get 9 and a remainder of 372.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 5985 from 6357 leaves us with 372.
Fetch the next digit (8) from the dividend, attach it to 372 and continue: 3728 / 665

Moving on to step 5:
The number 665 fits into 3728 5 times, leaving a remainder of 403.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 3325 from 3728 and we're left with 403.
Take the next digit (7) from the dividend and append it to 403, then repeat: 4037 / 665

Step 6:
665 can be fit into 4037 6 times, resulting in a remainder of 47.
The next digit of our result is 6. 
Result so far: 956.0
If we subtract 3990 from 4037, we get 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 665

Let's proceed to step 7:
665 goes into 475 0 times with a remainder of 475.
Put 0 as the next digit of the answer. 
Result so far: 9560.0
Subtract 0 from 475 to get 475.
Fetch the next digit (1) from the dividend, attach it to 475 and continue: 4751 / 665

Step 8:
The number 665 fits into 4751 7 times, leaving a remainder of 96.
Write down 7 as next digit of the result. 
Result so far: 95607.0
The remainder is 96 after subtracting 4655 from 4751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
When dividing 960 by 665, we get 1 with a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 95607.1
Deduct 665 from 960 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 10:
665 can be fit into 2950 4 times, resulting in a remainder of 290.
The next digit of our result is 4. 
Result so far: 95607.14
Deduct 2660 from 2950 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 11:
2900 divided by 665 is 4 with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 95607.144
If we subtract 2660 from 2900, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 95607.144 with a balance of 0.024.
