Let's divide 280431 by 73
The aim is to understand the frequency of 73 in 280431.

Moving on to step 1:
If we divide 2 by 73, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 73

Let's proceed to step 2:
When dividing 28 by 73, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 73

Moving on to step 3:
When dividing 280 by 73, we get 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 219 from 280 leaves us with 61.
Grab the next digit (4) from the dividend, add it to 61, then carry on: 614 / 73

Advancing to step 4:
73 can be fit into 614 8 times, resulting in a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 584 from 614, we get 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 73

Let's proceed to step 5:
73 can be fit into 303 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 384.0
Subtracting 292 from 303 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 73

Going ahead to step 6:
111 divided by 73 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 3841.0
Deduct 73 from 111 and we're left 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.

On to step 7:
73 goes into 380 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 3841.5
If we take 365 away from 380, we end up 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.

Moving on to step 8:
When dividing 150 by 73, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 3841.52
If we take 146 away from 150, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 73, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3841.52
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 10:
If we divide 400 by 73, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3841.5205
Subtracting 365 from 400 leaves us 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.

Advancing to step 11:
The number 73 fits into 350 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 3841.52054
Deduct 292 from 350 and we're left 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.

On to step 12:
The number 73 fits into 580 7 times, leaving a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 3841.520547
If we take 511 away from 580, we end up 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.

Advancing to step 13:
If we divide 690 by 73, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 3841.5205479
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.

Going ahead to step 14:
330 divided by 73 is 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 3841.52054794
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.

The final result is 3841.52054794 with a remainder of 3.8e-08.
