217636 ÷ 73 
The aim is to understand the frequency of 73 in 217636.

Advancing to step 1:
73 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 73

Let's proceed to step 2:
When dividing 21 by 73, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 73

Going ahead to step 3:
When dividing 217 by 73, we get 2 with a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 146 from 217 to get 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 73

Moving on to step 4:
73 can be fit into 716 9 times, resulting in a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 59 after subtracting 657 from 716.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 73

Let's proceed to step 5:
The number 73 fits into 593 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 298.0
Deduct 584 from 593 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 73

Advancing to step 6:
When dividing 96 by 73, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 2981.0
Deduct 73 from 96 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
If we divide 230 by 73, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 2981.3
The remainder is 11 after subtracting 219 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
When dividing 110 by 73, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 2981.31
Subtracting 73 from 110 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
73 goes into 370 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2981.315
If we subtract 365 from 370, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
When dividing 50 by 73, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 2981.315
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
500 divided by 73 is 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 2981.31506
Subtracting 438 from 500 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
73 goes into 620 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 2981.315068
If we take 584 away from 620, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
360 divided by 73 is 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 2981.3150684
If we subtract 292 from 360, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
680 divided by 73 is 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 2981.31506849
If we subtract 657 from 680, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 2981.31506849 with a remaining 2.3e-08.
