86261 divided by 72 
The aim is to understand the frequency of 72 in 86261.

Advancing to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 72

Advancing to step 2:
When dividing 86 by 72, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 14 after subtracting 72 from 86.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 72

Let's proceed to step 3:
142 divided by 72 is 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 72 away from 142, we end up with 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 72

Step 4:
If we divide 706 by 72, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 119.0
The remainder is 58 after subtracting 648 from 706.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 72

Let's proceed to step 5:
72 can be fit into 581 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 1198.0
Subtracting 576 from 581 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 6:
72 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1198.0
If we subtract 0 from 50, we get 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 7:
If we divide 500 by 72, we get 6 and a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 1198.06
Subtracting 432 from 500 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
72 can be fit into 680 9 times, resulting in a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 1198.069
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 72, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1198.0694
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
72 goes into 320 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 1198.06944
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 1198.06944, with a leftover of 3.2e-05.
