We look at the division of 497268 by 87 
The aim is to understand the frequency of 87 in 497268.

Step 1:
87 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 87

Going ahead to step 2:
If we divide 49 by 87, we get 0 and a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 87

Moving on to step 3:
87 goes into 497 5 times with a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 435 away from 497, we end up with 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 87

Going ahead to step 4:
87 can be fit into 622 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 57.0
Deduct 609 from 622 and we're left with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 87

Moving on to step 5:
When dividing 136 by 87, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 571.0
Deduct 87 from 136 and we're left with 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 87

Advancing to step 6:
87 can be fit into 498 5 times, resulting in a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 5715.0
Deduct 435 from 498 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
87 can be fit into 630 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 5715.7
Subtracting 609 from 630 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
If we divide 210 by 87, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 5715.72
If we take 174 away from 210, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 87 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 5715.724
Subtracting 348 from 360 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
87 goes into 120 1 times with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 5715.7241
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
87 goes into 330 3 times with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 5715.72413
If we subtract 261 from 330, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
The number 87 fits into 690 7 times, leaving a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 5715.724137
Deduct 609 from 690 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 13:
87 goes into 810 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 5715.7241379
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
The number 87 fits into 270 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 5715.72413793
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 5715.72413793 with a balance of 9e-09.
