783073 divided by 73 
The aim is to understand the frequency of 73 in 783073.

On to step 1:
73 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 73

Going ahead to step 2:
When dividing 78 by 73, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 73 away from 78, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 73

Advancing to step 3:
53 divided by 73 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 73

Let's proceed to step 4:
73 can be fit into 530 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtract 511 from 530 to get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 73

Advancing to step 5:
When dividing 197 by 73, we get 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 1072.0
Subtract 146 from 197 to get 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 73

Let's proceed to step 6:
The number 73 fits into 513 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 10727.0
The remainder is 2 after subtracting 511 from 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 73 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10727.0
Deduct 0 from 20 and we're left 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.

Going ahead to step 8:
If we divide 200 by 73, we get 2 and a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 10727.02
Subtract 146 from 200 to 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:
The number 73 fits into 540 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 10727.027
Subtract 511 from 540 to 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:
The number 73 fits into 290 3 times, leaving a remainder of 71.
The next digit of our result is 3. 
Result so far: 10727.0273
Subtracting 219 from 290 leaves us 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.

Moving on to step 11:
73 goes into 710 9 times with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 10727.02739
If we subtract 657 from 710, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 12:
If we divide 530 by 73, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 10727.027397
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.

Going ahead to step 13:
The number 73 fits into 190 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 10727.0273972
If we take 146 away from 190, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
73 goes into 440 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 10727.02739726
Subtracting 438 from 440 leaves us 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 10727.02739726 and a remainder of 2e-09.
