We're dividing 723773 by 51 
The aim is to understand the frequency of 51 in 723773.

Let's proceed to step 1:
When dividing 7 by 51, we get 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.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 51

Moving on to step 2:
51 goes into 72 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 51 from 72 leaves us with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 51

Moving on to step 3:
The number 51 fits into 213 4 times, leaving a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 204 from 213 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 51

Let's proceed to step 4:
97 divided by 51 is 1 with a remainder of 46.
The next digit of our result is 1. 
Result so far: 141.0
If we subtract 51 from 97, we get 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 51

Moving on to step 5:
When dividing 467 by 51, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 1419.0
The remainder is 8 after subtracting 459 from 467.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 51

Moving on to step 6:
When dividing 83 by 51, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 14191.0
Deduct 51 from 83 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
When dividing 320 by 51, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 14191.6
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
51 goes into 140 2 times with a remainder of 38.
The next digit of our result is 2. 
Result so far: 14191.62
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
51 goes into 380 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 14191.627
If we take 357 away from 380, we end up 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.

Let's proceed to step 10:
When dividing 230 by 51, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 14191.6274
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 14191.62745
If we subtract 255 from 260, 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.

Let's proceed to step 12:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 14191.62745
Subtract 0 from 50 to get 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 13:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 14191.6274509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
If we divide 410 by 51, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 14191.62745098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 14191.62745098 with a remaining 2e-09.
