We look at the division of 730951 by 73 
The aim is to understand the frequency of 73 in 730951.

Going ahead to step 1:
7 divided by 73 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 73

Moving on to step 2:
If we divide 73 by 73, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 73 from 73 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 73

Step 3:
The number 73 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 73

On to step 4:
73 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 9 to get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 73

Let's proceed to step 5:
When dividing 95 by 73, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1001.0
Subtracting 73 from 95 leaves us with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 73

Moving on to step 6:
73 can be fit into 221 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 10013.0
The remainder is 2 after subtracting 219 from 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
73 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10013.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 73, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 10013.02
If we subtract 146 from 200, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
When dividing 540 by 73, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 10013.027
If we subtract 511 from 540, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
290 divided by 73 is 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 10013.0273
If we take 219 away from 290, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 11:
73 can be fit into 710 9 times, resulting in a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 10013.02739
Deduct 657 from 710 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
The number 73 fits into 530 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 10013.027397
If we subtract 511 from 530, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
If we divide 190 by 73, we get 2 and a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 10013.0273972
The remainder is 44 after subtracting 146 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
When dividing 440 by 73, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 10013.02739726
If we take 438 away from 440, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 10013.02739726 and a remainder of 2e-09.
