We divide 72989927 by 560
The aim is to understand the frequency of 560 in 72989927.

Step 1:
When dividing 7 by 560, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 560

Moving on to step 2:
72 divided by 560 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 560

Advancing to step 3:
The number 560 fits into 729 1 times, leaving a remainder of 169.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 560 from 729 leaves us with 169.
Grab the next digit (8) from the dividend, add it to 169, then carry on: 1698 / 560

Let's proceed to step 4:
If we divide 1698 by 560, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1680 away from 1698, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 560

On to step 5:
If we divide 189 by 560, we get 0 and a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
The remainder is 189 after subtracting 0 from 189.
Include the next digit (9) from the dividend after 189, then repeat: 1899 / 560

Step 6:
If we divide 1899 by 560, we get 3 and a remainder of 219.
Use 3 as the next digit of our solution. 
Result so far: 1303.0
If we subtract 1680 from 1899, we get 219.
Include the next digit (2) from the dividend after 219, then repeat: 2192 / 560

Going ahead to step 7:
560 can be fit into 2192 3 times, resulting in a remainder of 512.
Put 3 as the next digit of the answer. 
Result so far: 13033.0
Deduct 1680 from 2192 and we're left with 512.
Append the next digit (7) from the dividend to 512 and continue with: 5127 / 560

Going ahead to step 8:
If we divide 5127 by 560, we get 9 and a remainder of 87.
Write down 9 as next digit of the result. 
Result so far: 130339.0
Subtract 5040 from 5127 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
If we divide 870 by 560, we get 1 and a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 130339.1
If we subtract 560 from 870, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
When dividing 3100 by 560, we get 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 130339.15
The remainder is 300 after subtracting 2800 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
The number 560 fits into 3000 5 times, leaving a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 130339.155
Subtract 2800 from 3000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 130339.155 and a remainder of 0.02.
