726949 ÷ 51 
The aim is to understand the frequency of 51 in 726949.

Step 1:
51 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 51

On to step 2:
72 divided by 51 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 72 and we're left with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 51

Going ahead to step 3:
216 divided by 51 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 204 from 216 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 51

Let's proceed to step 4:
51 can be fit into 129 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 142.0
The remainder is 27 after subtracting 102 from 129.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 51

On to step 5:
If we divide 274 by 51, we get 5 and a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 1425.0
Deduct 255 from 274 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 51

Advancing to step 6:
If we divide 199 by 51, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 14253.0
Subtract 153 from 199 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 14253.9
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
When dividing 10 by 51, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 14253.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
51 can be fit into 100 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 14253.901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
51 goes into 490 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 14253.9019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 14253.90196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
If we divide 40 by 51, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 14253.90196
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
400 divided by 51 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 14253.9019607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 14:
51 goes into 430 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 14253.90196078
If we subtract 408 from 430, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 14253.90196078 with a remainder of 2.2e-08.
