453239 ÷ 73 
The aim is to understand the frequency of 73 in 453239.

Step 1:
The number 73 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 73

Moving on to step 2:
73 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 73

On to step 3:
If we divide 453 by 73, we get 6 and a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 438 from 453 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 73

On to step 4:
152 divided by 73 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtracting 146 from 152 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 73

Let's proceed to step 5:
73 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 620.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 73

Let's proceed to step 6:
When dividing 639 by 73, we get 8 with a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 6208.0
If we take 584 away from 639, we end up 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.

Moving on to step 7:
73 can be fit into 550 7 times, resulting in a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 6208.7
Deduct 511 from 550 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
If we divide 390 by 73, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6208.75
Subtract 365 from 390 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.

Step 9:
73 goes into 250 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 6208.753
Deduct 219 from 250 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
310 divided by 73 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 6208.7534
Deduct 292 from 310 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
73 can be fit into 180 2 times, resulting in a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 6208.75342
Deduct 146 from 180 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
The number 73 fits into 340 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 6208.753424
Deduct 292 from 340 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
73 can be fit into 480 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 6208.7534246
Subtracting 438 from 480 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
When dividing 420 by 73, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 6208.75342465
Subtracting 365 from 420 leaves us 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.

In conclusion, the division gives 6208.75342465 with a balance of 5.5e-08.
