We're dividing 437240 by 73 
The aim is to understand the frequency of 73 in 437240.

Step 1:
When dividing 4 by 73, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 73

On to step 2:
When dividing 43 by 73, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 73

Step 3:
The number 73 fits into 437 5 times, leaving a remainder of 72.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 365 from 437 leaves us with 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 73

Going ahead to step 4:
73 goes into 722 9 times with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 65 after subtracting 657 from 722.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 73

Moving on to step 5:
73 can be fit into 654 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 598.0
If we take 584 away from 654, we end up with 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 73

On to step 6:
The number 73 fits into 700 9 times, leaving a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 5989.0
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
If we divide 430 by 73, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 5989.5
Subtract 365 from 430 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
The number 73 fits into 650 8 times, leaving a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 5989.58
Deduct 584 from 650 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
660 divided by 73 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 5989.589
Deduct 657 from 660 and we're left 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.

Going ahead to step 10:
73 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5989.589
If we take 0 away from 30, 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 11:
300 divided by 73 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5989.58904
If we take 292 away from 300, we end up with 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 12:
When dividing 80 by 73, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 5989.589041
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.

On to step 13:
70 divided by 73 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 5989.589041
The remainder is 70 after subtracting 0 from 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 14:
When dividing 700 by 73, we get 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 5989.58904109
If we subtract 657 from 700, we 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.

In conclusion, the division gives 5989.58904109 with a balance of 4.3e-08.
