502838 ÷ 73 
The aim is to understand the frequency of 73 in 502838.

Let's proceed to step 1:
5 divided by 73 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 73

Going ahead to step 2:
50 divided by 73 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 73

Step 3:
73 can be fit into 502 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 438 from 502 to get 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 73

Going ahead to step 4:
73 goes into 648 8 times with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 68.0
The remainder is 64 after subtracting 584 from 648.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 73

Let's proceed to step 5:
If we divide 643 by 73, we get 8 and a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 688.0
If we take 584 away from 643, we end up with 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 73

Step 6:
598 divided by 73 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 6888.0
Deduct 584 from 598 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 73 fits into 140 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 6888.1
The remainder is 67 after subtracting 73 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 8:
The number 73 fits into 670 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 6888.19
Subtracting 657 from 670 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
130 divided by 73 is 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 6888.191
Deduct 73 from 130 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
73 goes into 570 7 times with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 6888.1917
Subtract 511 from 570 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
73 can be fit into 590 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 6888.19178
Subtracting 584 from 590 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
60 divided by 73 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 6888.19178
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
The number 73 fits into 600 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 6888.1917808
Subtract 584 from 600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
If we divide 160 by 73, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 6888.19178082
Subtract 146 from 160 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 6888.19178082, with a leftover of 1.4e-08.
