We're dividing 86569765 by 726 
The aim is to understand the frequency of 726 in 86569765.

Let's proceed to step 1:
The number 726 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 726

Going ahead to step 2:
726 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 726

On to step 3:
When dividing 865 by 726, we get 1 with a remainder of 139.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 726 from 865 to get 139.
Bring next digit (6) of the dividend behind the 139 and repeat the process: 1396 / 726

Going ahead to step 4:
726 goes into 1396 1 times with a remainder of 670.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 670 after subtracting 726 from 1396.
Grab the next digit (9) from the dividend, add it to 670, then carry on: 6709 / 726

On to step 5:
If we divide 6709 by 726, we get 9 and a remainder of 175.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 6534 from 6709 leaves us with 175.
Take the next digit (7) from the dividend and append it to 175, then repeat: 1757 / 726

Moving on to step 6:
726 goes into 1757 2 times with a remainder of 305.
The next digit of our result is 2. 
Result so far: 1192.0
Subtract 1452 from 1757 to get 305.
Fetch the next digit (6) from the dividend, attach it to 305 and continue: 3056 / 726

Advancing to step 7:
726 goes into 3056 4 times with a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 11924.0
Subtracting 2904 from 3056 leaves us with 152.
Bring next digit (5) of the dividend behind the 152 and repeat the process: 1525 / 726

On to step 8:
When dividing 1525 by 726, we get 2 with a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 119242.0
If we subtract 1452 from 1525, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
726 can be fit into 730 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 119242.1
Subtract 726 from 730 to 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.

Step 10:
If we divide 40 by 726, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 119242.1
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
The number 726 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 119242.1
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 119242.1, with a leftover of 0.04.
