We look at the division of 98874159 by 565 
The aim is to understand the frequency of 565 in 98874159.

Moving on to step 1:
The number 565 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 565

Moving on to step 2:
565 can be fit into 98 0 times, resulting in a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Include the next digit (8) from the dividend after 98, then repeat: 988 / 565

Let's proceed to step 3:
The number 565 fits into 988 1 times, leaving a remainder of 423.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 423 after subtracting 565 from 988.
Bring next digit (7) of the dividend behind the 423 and repeat the process: 4237 / 565

Advancing to step 4:
The number 565 fits into 4237 7 times, leaving a remainder of 282.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 282 after subtracting 3955 from 4237.
Bring next digit (4) of the dividend behind the 282 and repeat the process: 2824 / 565

On to step 5:
2824 divided by 565 is 4 with a remainder of 564.
Write down 4 as next digit of the result. 
Result so far: 174.0
If we take 2260 away from 2824, we end up with 564.
Fetch the next digit (1) from the dividend, attach it to 564 and continue: 5641 / 565

Let's proceed to step 6:
If we divide 5641 by 565, we get 9 and a remainder of 556.
The number 9 becomes the next digit in our result. 
Result so far: 1749.0
Deduct 5085 from 5641 and we're left with 556.
Fetch the next digit (5) from the dividend, attach it to 556 and continue: 5565 / 565

Moving on to step 7:
565 can be fit into 5565 9 times, resulting in a remainder of 480.
Put 9 as the next digit of the answer. 
Result so far: 17499.0
Subtract 5085 from 5565 to get 480.
Append the next digit (9) from the dividend to 480 and continue with: 4809 / 565

Step 8:
If we divide 4809 by 565, we get 8 and a remainder of 289.
Use 8 as the next digit of our solution. 
Result so far: 174998.0
Subtracting 4520 from 4809 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 9:
565 can be fit into 2890 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 174998.5
The remainder is 65 after subtracting 2825 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
565 can be fit into 650 1 times, resulting in a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 174998.51
Subtracting 565 from 650 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
565 can be fit into 850 1 times, resulting in a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 174998.511
Subtract 565 from 850 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

After the division, we end up with 174998.511 and a remainder of 0.0285.
