We're dividing 85645215 by 72 
The aim is to understand the frequency of 72 in 85645215.

Advancing to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 72

Let's proceed to step 2:
72 goes into 85 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 72 from 85 leaves us with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 72

Let's proceed to step 3:
72 can be fit into 136 1 times, resulting in a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 72 from 136 and we're left with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 72

Going ahead to step 4:
The number 72 fits into 644 8 times, leaving a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 118.0
Deduct 576 from 644 and we're left with 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 72

Moving on to step 5:
685 divided by 72 is 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 1189.0
If we take 648 away from 685, we end up with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 72

Going ahead to step 6:
The number 72 fits into 372 5 times, leaving a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 11895.0
Subtract 360 from 372 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 72

Step 7:
When dividing 121 by 72, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 118951.0
If we subtract 72 from 121, we get 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 72

Going ahead to step 8:
72 can be fit into 495 6 times, resulting in a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 1189516.0
Subtract 432 from 495 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
72 can be fit into 630 8 times, resulting in a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 1189516.8
If we take 576 away from 630, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 72, we get 7 and a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 1189516.87
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
360 divided by 72 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1189516.875
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
When dividing 0 by 72, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1189516.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
0 divided by 72 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1189516.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1189516.875 with a balance of 0.0.
