72500529 ÷ 165 
The aim is to understand the frequency of 165 in 72500529.

Let's proceed to step 1:
The number 165 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 165

Going ahead to step 2:
165 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 165

Going ahead to step 3:
The number 165 fits into 725 4 times, leaving a remainder of 65.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 660 from 725, we get 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 165

Moving on to step 4:
If we divide 650 by 165, we get 3 and a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 495 from 650 leaves us with 155.
Append the next digit (0) from the dividend to 155 and continue with: 1550 / 165

Advancing to step 5:
When dividing 1550 by 165, we get 9 with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 439.0
Subtracting 1485 from 1550 leaves us with 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 165

Let's proceed to step 6:
When dividing 655 by 165, we get 3 with a remainder of 160.
The number 3 becomes the next digit in our result. 
Result so far: 4393.0
If we take 495 away from 655, we end up with 160.
Append the next digit (2) from the dividend to 160 and continue with: 1602 / 165

On to step 7:
165 can be fit into 1602 9 times, resulting in a remainder of 117.
Use 9 as the next digit of our solution. 
Result so far: 43939.0
The remainder is 117 after subtracting 1485 from 1602.
Include the next digit (9) from the dividend after 117, then repeat: 1179 / 165

Let's proceed to step 8:
1179 divided by 165 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 439397.0
If we subtract 1155 from 1179, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
165 goes into 240 1 times with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 439397.1
The remainder is 75 after subtracting 165 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
The number 165 fits into 750 4 times, leaving a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 439397.14
If we subtract 660 from 750, we get 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 11:
When dividing 900 by 165, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 439397.145
Subtracting 825 from 900 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
When dividing 750 by 165, we get 4 with a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 439397.1454
If we subtract 660 from 750, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
The number 165 fits into 900 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 439397.14545
Deduct 825 from 900 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
The number 165 fits into 750 4 times, leaving a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 439397.145454
If we subtract 660 from 750, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 15:
165 can be fit into 900 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 439397.1454545
Subtracting 825 from 900 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 16:
The number 165 fits into 750 4 times, leaving a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 439397.14545454
If we take 660 away from 750, we end up 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.

In conclusion, the division gives 439397.14545454 with a balance of 9e-08.
