13901446 ÷ 726 
The aim is to understand the frequency of 726 in 13901446.

On to step 1:
The number 726 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 726

Step 2:
The number 726 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 726

Step 3:
726 goes into 139 0 times with a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Take the next digit (0) from the dividend and append it to 139, then repeat: 1390 / 726

On to step 4:
1390 divided by 726 is 1 with a remainder of 664.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 726 away from 1390, we end up with 664.
Bring next digit (1) of the dividend behind the 664 and repeat the process: 6641 / 726

Step 5:
If we divide 6641 by 726, we get 9 and a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 6534 from 6641, we get 107.
Bring next digit (4) of the dividend behind the 107 and repeat the process: 1074 / 726

Going ahead to step 6:
726 can be fit into 1074 1 times, resulting in a remainder of 348.
Write down 1 as next digit of the result. 
Result so far: 191.0
Deduct 726 from 1074 and we're left with 348.
Bring next digit (4) of the dividend behind the 348 and repeat the process: 3484 / 726

Step 7:
The number 726 fits into 3484 4 times, leaving a remainder of 580.
The number 4 becomes the next digit in our result. 
Result so far: 1914.0
The remainder is 580 after subtracting 2904 from 3484.
Append the next digit (6) from the dividend to 580 and continue with: 5806 / 726

Step 8:
5806 divided by 726 is 7 with a remainder of 724.
The next digit of our result is 7. 
Result so far: 19147.0
Deduct 5082 from 5806 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 9:
The number 726 fits into 7240 9 times, leaving a remainder of 706.
The number 9 becomes the next digit in our result. 
Result so far: 19147.9
Deduct 6534 from 7240 and we're left with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 10:
If we divide 7060 by 726, we get 9 and a remainder of 526.
Put 9 as the next digit of the answer. 
Result so far: 19147.99
The remainder is 526 after subtracting 6534 from 7060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

In conclusion, the division gives 19147.99 with a balance of 0.526.
