We're dividing 72802521 by 608 
The aim is to understand the frequency of 608 in 72802521.

Step 1:
The number 608 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 608

On to step 2:
If we divide 72 by 608, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 608

Let's proceed to step 3:
608 goes into 728 1 times with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 608 away from 728, we end up with 120.
Take the next digit (0) from the dividend and append it to 120, then repeat: 1200 / 608

Advancing to step 4:
The number 608 fits into 1200 1 times, leaving a remainder of 592.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 592 after subtracting 608 from 1200.
Fetch the next digit (2) from the dividend, attach it to 592 and continue: 5922 / 608

Going ahead to step 5:
608 can be fit into 5922 9 times, resulting in a remainder of 450.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtracting 5472 from 5922 leaves us with 450.
Append the next digit (5) from the dividend to 450 and continue with: 4505 / 608

Going ahead to step 6:
When dividing 4505 by 608, we get 7 with a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
If we take 4256 away from 4505, we end up with 249.
Fetch the next digit (2) from the dividend, attach it to 249 and continue: 2492 / 608

On to step 7:
The number 608 fits into 2492 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 11974.0
Subtract 2432 from 2492 to get 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 608

On to step 8:
If we divide 601 by 608, we get 0 and a remainder of 601.
Write down 0 as next digit of the result. 
Result so far: 119740.0
Subtract 0 from 601 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 9:
When dividing 6010 by 608, we get 9 with a remainder of 538.
Put 9 as the next digit of the answer. 
Result so far: 119740.9
Subtract 5472 from 6010 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 10:
When dividing 5380 by 608, we get 8 with a remainder of 516.
Use 8 as the next digit of our solution. 
Result so far: 119740.98
Deduct 4864 from 5380 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 11:
5160 divided by 608 is 8 with a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 119740.988
The remainder is 296 after subtracting 4864 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The quotient of the division is 119740.988, and the remainder is 0.0296.
