82515 ÷ 73 
The aim is to understand the frequency of 73 in 82515.

On to step 1:
When dividing 8 by 73, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 73

Advancing to step 2:
73 goes into 82 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 73 from 82 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 73

Step 3:
The number 73 fits into 95 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 73 from 95 leaves us with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 73

Moving on to step 4:
73 can be fit into 221 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtracting 219 from 221 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 73

Advancing to step 5:
The number 73 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 1130.0
The remainder is 25 after subtracting 0 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 6:
When dividing 250 by 73, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 1130.3
If we subtract 219 from 250, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
73 goes into 310 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1130.34
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.

Step 8:
The number 73 fits into 180 2 times, leaving a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 1130.342
Subtracting 146 from 180 leaves us 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.

Going ahead to step 9:
340 divided by 73 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 1130.3424
If we subtract 292 from 340, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
The number 73 fits into 480 6 times, leaving a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 1130.34246
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 11:
73 can be fit into 420 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1130.342465
Subtract 365 from 420 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
The number 73 fits into 550 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 1130.3424657
If we take 511 away from 550, we end up 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.

Advancing to step 13:
390 divided by 73 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1130.34246575
If we take 365 away from 390, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 1130.34246575 with a remaining 2.5e-08.
