We're dividing 72650033 by 145 
The aim is to understand the frequency of 145 in 72650033.

Step 1:
When dividing 7 by 145, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 145

On to step 2:
The number 145 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 145

Going ahead to step 3:
145 goes into 726 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 725 from 726, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 145

Moving on to step 4:
15 divided by 145 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 145

On to step 5:
When dividing 150 by 145, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 501.0
Deduct 145 from 150 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 145

Step 6:
145 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5010.0
If we subtract 0 from 50, we get 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 145

On to step 7:
145 can be fit into 503 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 50103.0
Subtracting 435 from 503 leaves us with 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 145

Advancing to step 8:
683 divided by 145 is 4 with a remainder of 103.
Use 4 as the next digit of our solution. 
Result so far: 501034.0
If we subtract 580 from 683, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 9:
When dividing 1030 by 145, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 501034.7
If we take 1015 away from 1030, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
When dividing 150 by 145, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 501034.71
If we take 145 away from 150, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
The number 145 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 501034.71
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
145 goes into 500 3 times with a remainder of 65.
The next digit of our result is 3. 
Result so far: 501034.7103
Subtracting 435 from 500 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
The number 145 fits into 650 4 times, leaving a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 501034.71034
The remainder is 70 after subtracting 580 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
When dividing 700 by 145, we get 4 with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 501034.710344
If we subtract 580 from 700, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 501034.710344 and a remainder of 1.2e-05.
