Let's divide 898620 by 72
The aim is to understand the frequency of 72 in 898620.

Moving on to step 1:
8 divided by 72 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 72

On to step 2:
The number 72 fits into 89 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 72 away from 89, we end up with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 72

Step 3:
72 goes into 178 2 times with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 144 away from 178, we end up with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 72

Moving on to step 4:
The number 72 fits into 346 4 times, leaving a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Deduct 288 from 346 and we're left with 58.
Bring next digit (2) of the dividend behind the 58 and repeat the process: 582 / 72

Advancing to step 5:
582 divided by 72 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 1248.0
Subtracting 576 from 582 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 72

On to step 6:
72 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 12480.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
600 divided by 72 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 12480.8
Subtracting 576 from 600 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
72 can be fit into 240 3 times, resulting in a remainder of 24.
The next digit of our result is 3. 
Result so far: 12480.83
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 72 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 12480.833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 12480.833, and the remainder is 0.0024.
