52746755 ÷ 726 
The aim is to understand the frequency of 726 in 52746755.

Advancing to step 1:
When dividing 5 by 726, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 726

Moving on to step 2:
If we divide 52 by 726, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 726

Advancing to step 3:
726 goes into 527 0 times with a remainder of 527.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 527 to get 527.
Take the next digit (4) from the dividend and append it to 527, then repeat: 5274 / 726

Going ahead to step 4:
If we divide 5274 by 726, we get 7 and a remainder of 192.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5082 away from 5274, we end up with 192.
Bring next digit (6) of the dividend behind the 192 and repeat the process: 1926 / 726

Step 5:
726 goes into 1926 2 times with a remainder of 474.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 1452 from 1926, we get 474.
Append the next digit (7) from the dividend to 474 and continue with: 4747 / 726

On to step 6:
726 goes into 4747 6 times with a remainder of 391.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.0
Subtracting 4356 from 4747 leaves us with 391.
Grab the next digit (5) from the dividend, add it to 391, then carry on: 3915 / 726

Step 7:
The number 726 fits into 3915 5 times, leaving a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 7265.0
If we take 3630 away from 3915, we end up with 285.
Bring next digit (5) of the dividend behind the 285 and repeat the process: 2855 / 726

Going ahead to step 8:
726 can be fit into 2855 3 times, resulting in a remainder of 677.
Put 3 as the next digit of the answer. 
Result so far: 72653.0
If we take 2178 away from 2855, we end up with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Moving on to step 9:
If we divide 6770 by 726, we get 9 and a remainder of 236.
The number 9 becomes the next digit in our result. 
Result so far: 72653.9
Deduct 6534 from 6770 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 10:
The number 726 fits into 2360 3 times, leaving a remainder of 182.
The next digit of our result is 3. 
Result so far: 72653.93
Subtract 2178 from 2360 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 11:
726 can be fit into 1820 2 times, resulting in a remainder of 368.
Use 2 as the next digit of our solution. 
Result so far: 72653.932
If we subtract 1452 from 1820, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
726 goes into 3680 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 72653.9325
Subtracting 3630 from 3680 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
726 can be fit into 500 0 times, resulting in a remainder of 500.
The next digit of our result is 0. 
Result so far: 72653.9325
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
5000 divided by 726 is 6 with a remainder of 644.
Put 6 as the next digit of the answer. 
Result so far: 72653.932506
Subtracting 4356 from 5000 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 15:
726 can be fit into 6440 8 times, resulting in a remainder of 632.
Record the quotient 8 as the next digit in the result. 
Result so far: 72653.9325068
The remainder is 632 after subtracting 5808 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 16:
726 goes into 6320 8 times with a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 72653.93250688
Deduct 5808 from 6320 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final result is 72653.93250688 with a remainder of 5.12e-07.
