9765256 ÷ 726 
The aim is to understand the frequency of 726 in 9765256.

Let's proceed to step 1:
When dividing 9 by 726, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 726

Step 2:
The number 726 fits into 97 0 times, leaving a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Fetch the next digit (6) from the dividend, attach it to 97 and continue: 976 / 726

Let's proceed to step 3:
When dividing 976 by 726, we get 1 with a remainder of 250.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 726 from 976 and we're left with 250.
Bring next digit (5) of the dividend behind the 250 and repeat the process: 2505 / 726

On to step 4:
726 can be fit into 2505 3 times, resulting in a remainder of 327.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 2178 from 2505 and we're left with 327.
Bring next digit (2) of the dividend behind the 327 and repeat the process: 3272 / 726

Advancing to step 5:
726 goes into 3272 4 times with a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we take 2904 away from 3272, we end up with 368.
Fetch the next digit (5) from the dividend, attach it to 368 and continue: 3685 / 726

Step 6:
726 can be fit into 3685 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 1345.0
If we take 3630 away from 3685, we end up with 55.
Include the next digit (6) from the dividend after 55, then repeat: 556 / 726

Advancing to step 7:
The number 726 fits into 556 0 times, leaving a remainder of 556.
The number 0 becomes the next digit in our result. 
Result so far: 13450.0
Deduct 0 from 556 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 8:
726 goes into 5560 7 times with a remainder of 478.
Write down 7 as next digit of the result. 
Result so far: 13450.7
Subtract 5082 from 5560 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 9:
When dividing 4780 by 726, we get 6 with a remainder of 424.
Put 6 as the next digit of the answer. 
Result so far: 13450.76
Deduct 4356 from 4780 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 10:
The number 726 fits into 4240 5 times, leaving a remainder of 610.
Put 5 as the next digit of the answer. 
Result so far: 13450.765
Deduct 3630 from 4240 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 11:
The number 726 fits into 6100 8 times, leaving a remainder of 292.
Use 8 as the next digit of our solution. 
Result so far: 13450.7658
Subtract 5808 from 6100 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 12:
The number 726 fits into 2920 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 13450.76584
Deduct 2904 from 2920 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
726 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 13450.76584
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
726 can be fit into 1600 2 times, resulting in a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 13450.7658402
Subtracting 1452 from 1600 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 15:
If we divide 1480 by 726, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 13450.76584022
Subtracting 1452 from 1480 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 13450.76584022 and a remainder of 2.8e-08.
