We look at the division of 598698 by 72 
The aim is to understand the frequency of 72 in 598698.

Going ahead to step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 72

Moving on to step 2:
72 can be fit into 59 0 times, resulting in a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 72

Step 3:
72 can be fit into 598 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 576 from 598 leaves us with 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 72

Going ahead to step 4:
The number 72 fits into 226 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 10 after subtracting 216 from 226.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 72

Going ahead to step 5:
When dividing 109 by 72, we get 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 831.0
Subtracting 72 from 109 leaves us with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 72

Let's proceed to step 6:
The number 72 fits into 378 5 times, leaving a remainder of 18.
The next digit of our result is 5. 
Result so far: 8315.0
If we take 360 away from 378, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 72, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 8315.2
Deduct 144 from 180 and we're left with 36.
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 8:
360 divided by 72 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8315.25
If we take 360 away from 360, 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.

Moving on to step 9:
0 divided by 72 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8315.25
Subtract 0 from 0 to 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.

Let's proceed to step 10:
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: 8315.25
Subtract 0 from 0 to 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.

The final outcome is 8315.25, with a leftover of 0.0.
