531140 ÷ 73 
The aim is to understand the frequency of 73 in 531140.

Moving on to step 1:
The number 73 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 73

On to step 2:
If we divide 53 by 73, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 73

Going ahead to step 3:
73 goes into 531 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 511 away from 531, we end up with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 73

Step 4:
73 can be fit into 201 2 times, resulting in a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 146 from 201, we get 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 73

Advancing to step 5:
When dividing 554 by 73, we get 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 727.0
The remainder is 43 after subtracting 511 from 554.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 73

Advancing to step 6:
If we divide 430 by 73, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7275.0
The remainder is 65 after subtracting 365 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
If we divide 650 by 73, we get 8 and a remainder of 66.
The next digit of our result is 8. 
Result so far: 7275.8
The remainder is 66 after subtracting 584 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
The number 73 fits into 660 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 7275.89
If we take 657 away from 660, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 73, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 7275.89
Deduct 0 from 30 and we're left 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.

Moving on to step 10:
The number 73 fits into 300 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7275.8904
If we subtract 292 from 300, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
73 can be fit into 80 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 7275.89041
Deduct 73 from 80 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
73 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 7275.89041
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 7275.8904109
Subtract 657 from 700 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 14:
If we divide 430 by 73, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 7275.89041095
The remainder is 65 after subtracting 365 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 7275.89041095 with a remainder of 6.5e-08.
