We divide 497624 by 87
The aim is to understand the frequency of 87 in 497624.

Advancing to step 1:
If we divide 4 by 87, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 87

On to step 2:
49 divided by 87 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 87

On to step 3:
497 divided by 87 is 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 435 from 497, we get 62.
Take the next digit (6) from the dividend and append it to 62, then repeat: 626 / 87

On to step 4:
The number 87 fits into 626 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 609 away from 626, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 87

Going ahead to step 5:
87 can be fit into 172 1 times, resulting in a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 571.0
Deduct 87 from 172 and we're left with 85.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 87

Going ahead to step 6:
87 can be fit into 854 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 5719.0
If we take 783 away from 854, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
The number 87 fits into 710 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 5719.8
Subtracting 696 from 710 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
140 divided by 87 is 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 5719.81
The remainder is 53 after subtracting 87 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
530 divided by 87 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 5719.816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 87, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 5719.816
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
When dividing 800 by 87, we get 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 5719.81609
Subtract 783 from 800 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
87 can be fit into 170 1 times, resulting in a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 5719.816091
Subtract 87 from 170 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 13:
830 divided by 87 is 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 5719.8160919
Subtract 783 from 830 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 14:
87 goes into 470 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 5719.81609195
Subtract 435 from 470 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 5719.81609195 with a remaining 3.5e-08.
