We divide 638304 by 87
The aim is to understand the frequency of 87 in 638304.

Moving on to step 1:
87 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 87

Let's proceed to step 2:
63 divided by 87 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 87

Let's proceed to step 3:
87 can be fit into 638 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 609 away from 638, we end up with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 87

Advancing to step 4:
If we divide 293 by 87, we get 3 and a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 261 from 293 leaves us with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 87

Moving on to step 5:
87 goes into 320 3 times with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 733.0
Deduct 261 from 320 and we're left with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 87

Let's proceed to step 6:
When dividing 594 by 87, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 7336.0
If we subtract 522 from 594, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
720 divided by 87 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 7336.8
Subtract 696 from 720 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
If we divide 240 by 87, we get 2 and a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 7336.82
Subtracting 174 from 240 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
When dividing 660 by 87, we get 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 7336.827
Deduct 609 from 660 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 10:
87 goes into 510 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 7336.8275
Deduct 435 from 510 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
If we divide 750 by 87, we get 8 and a remainder of 54.
The next digit of our result is 8. 
Result so far: 7336.82758
The remainder is 54 after subtracting 696 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
If we divide 540 by 87, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 7336.827586
Subtracting 522 from 540 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
When dividing 180 by 87, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 7336.8275862
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
87 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7336.8275862
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 7336.8275862 and a remainder of 6e-08.
