We look at the division of 169498 by 72 
The aim is to understand the frequency of 72 in 169498.

Let's proceed to step 1:
When dividing 1 by 72, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 72

On to step 2:
72 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 72

Moving on to step 3:
169 divided by 72 is 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 25 after subtracting 144 from 169.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 72

On to step 4:
When dividing 254 by 72, we get 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 216 away from 254, we end up with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 72

Step 5:
72 goes into 389 5 times with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
If we take 360 away from 389, we end up with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 72

Advancing to step 6:
72 can be fit into 298 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2354.0
Deduct 288 from 298 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 72 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 2354.1
If we subtract 72 from 100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
When dividing 280 by 72, we get 3 with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 2354.13
Subtract 216 from 280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 2354.138
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
When dividing 640 by 72, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 2354.1388
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 2354.1388, and the remainder is 0.00064.
