We're dividing 24478 by 87 
The aim is to understand the frequency of 87 in 24478.

Step 1:
87 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 87

On to step 2:
When dividing 24 by 87, we get 0 with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 87

Moving on to step 3:
87 goes into 244 2 times with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 174 from 244 to get 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 87

Step 4:
When dividing 707 by 87, we get 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 696 from 707, we get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 87

Going ahead to step 5:
If we divide 118 by 87, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 281.0
If we subtract 87 from 118, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 6:
If we divide 310 by 87, we get 3 and a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 281.3
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
The number 87 fits into 490 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 281.35
If we subtract 435 from 490, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
550 divided by 87 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 281.356
Deduct 522 from 550 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 281.3563
Deduct 261 from 280 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 281.35632
Subtract 174 from 190 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 87, we get 1 and a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 281.356321
If we take 87 away from 160, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 12:
The number 87 fits into 730 8 times, leaving a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 281.3563218
Deduct 696 from 730 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
87 can be fit into 340 3 times, resulting in a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 281.35632183
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

After the division, we end up with 281.35632183 and a remainder of 7.9e-08.
