We divide 507225 by 65
The aim is to understand the frequency of 65 in 507225.

Going ahead to step 1:
If we divide 5 by 65, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 65

Let's proceed to step 2:
The number 65 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 65

Advancing to step 3:
The number 65 fits into 507 7 times, leaving a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 455 away from 507, we end up with 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 65

Advancing to step 4:
When dividing 522 by 65, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 2 after subtracting 520 from 522.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 65

On to step 5:
65 goes into 22 0 times with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 780.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 65

Going ahead to step 6:
The number 65 fits into 225 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 7803.0
Subtract 195 from 225 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
If we divide 300 by 65, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 7803.4
Subtract 260 from 300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 65, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 7803.46
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
65 goes into 100 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 7803.461
Subtract 65 from 100 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
65 goes into 350 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7803.4615
Subtract 325 from 350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
65 can be fit into 250 3 times, resulting in a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 7803.46153
Deduct 195 from 250 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 12:
65 can be fit into 550 8 times, resulting in a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 7803.461538
If we take 520 away from 550, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
When dividing 300 by 65, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 7803.4615384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
400 divided by 65 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 7803.46153846
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 7803.46153846 and a remainder of 1e-08.
