448306 ÷ 87 
The aim is to understand the frequency of 87 in 448306.

Going ahead to step 1:
4 divided by 87 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 87

On to step 2:
When dividing 44 by 87, we get 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 87

Let's proceed to step 3:
87 can be fit into 448 5 times, resulting in a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 435 from 448 and we're left with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 87

Advancing to step 4:
The number 87 fits into 133 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 87 from 133 to get 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 87

Step 5:
87 goes into 460 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 515.0
Subtract 435 from 460 to get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 87

Moving on to step 6:
The number 87 fits into 256 2 times, leaving a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 5152.0
Subtract 174 from 256 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
87 can be fit into 820 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 5152.9
Subtracting 783 from 820 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
The number 87 fits into 370 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 5152.94
If we subtract 348 from 370, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
When dividing 220 by 87, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 5152.942
If we take 174 away from 220, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
The number 87 fits into 460 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5152.9425
Deduct 435 from 460 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
250 divided by 87 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 5152.94252
Subtracting 174 from 250 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
760 divided by 87 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 5152.942528
Deduct 696 from 760 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
If we divide 640 by 87, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 5152.9425287
If we take 609 away from 640, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
If we divide 310 by 87, we get 3 and a remainder of 49.
The next digit of our result is 3. 
Result so far: 5152.94252873
Subtract 261 from 310 to 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.

The final outcome is 5152.94252873, with a leftover of 4.9e-08.
