Let's divide 821903 by 73
The aim is to understand the frequency of 73 in 821903.

Advancing to step 1:
The number 73 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 73

On to step 2:
If we divide 82 by 73, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 9 after subtracting 73 from 82.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 73

Moving on to step 3:
91 divided by 73 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 73 from 91 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 73

On to step 4:
73 can be fit into 189 2 times, resulting in a remainder of 43.
The next digit of our result is 2. 
Result so far: 112.0
If we subtract 146 from 189, we get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 73

Going ahead to step 5:
73 can be fit into 430 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 1125.0
Deduct 365 from 430 and we're left with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 73

Advancing to step 6:
The number 73 fits into 653 8 times, leaving a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 11258.0
Deduct 584 from 653 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
690 divided by 73 is 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 11258.9
Subtract 657 from 690 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 8:
The number 73 fits into 330 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 11258.94
Subtracting 292 from 330 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
When dividing 380 by 73, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 11258.945
Subtracting 365 from 380 leaves us 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:
If we divide 150 by 73, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 11258.9452
Subtract 146 from 150 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
If we divide 40 by 73, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 11258.9452
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
73 goes into 400 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 11258.945205
If we take 365 away from 400, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
73 goes into 350 4 times with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 11258.9452054
Subtracting 292 from 350 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
The number 73 fits into 580 7 times, leaving a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 11258.94520547
Subtracting 511 from 580 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 11258.94520547 and a remainder of 6.9e-08.
