Let's divide 83653585 by 72
The aim is to understand the frequency of 72 in 83653585.

Going ahead to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 72

Let's proceed to step 2:
When dividing 83 by 72, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 72 from 83 leaves us with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 72

Moving on to step 3:
When dividing 116 by 72, we get 1 with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 72 from 116, we get 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 72

Moving on to step 4:
445 divided by 72 is 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtract 432 from 445 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 72

Moving on to step 5:
72 goes into 133 1 times with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 1161.0
If we take 72 away from 133, we end up with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 72

Moving on to step 6:
72 goes into 615 8 times with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 11618.0
Subtract 576 from 615 to get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 72

Step 7:
The number 72 fits into 398 5 times, leaving a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 116185.0
Deduct 360 from 398 and we're left with 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 72

Going ahead to step 8:
The number 72 fits into 385 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1161855.0
The remainder is 25 after subtracting 360 from 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 72 fits into 250 3 times, leaving a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 1161855.3
If we subtract 216 from 250, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
72 can be fit into 340 4 times, resulting in a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 1161855.34
If we subtract 288 from 340, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
The number 72 fits into 520 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 1161855.347
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
160 divided by 72 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1161855.3472
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 72 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1161855.34722
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1161855.34722, with a leftover of 1.6e-05.
