We divide 573587 by 87
The aim is to understand the frequency of 87 in 573587.

Let's proceed to step 1:
87 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 87

Let's proceed to step 2:
The number 87 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 87

Step 3:
87 goes into 573 6 times with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 522 away from 573, we end up with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 87

Moving on to step 4:
515 divided by 87 is 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Deduct 435 from 515 and we're left with 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 87

Let's proceed to step 5:
87 can be fit into 808 9 times, resulting in a remainder of 25.
The next digit of our result is 9. 
Result so far: 659.0
Subtract 783 from 808 to get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 87

On to step 6:
If we divide 257 by 87, we get 2 and a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 6592.0
Subtract 174 from 257 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.

Advancing to step 7:
87 goes into 830 9 times with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 6592.9
Subtracting 783 from 830 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
The number 87 fits into 470 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 6592.95
Subtracting 435 from 470 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 87 fits into 350 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 6592.954
Subtract 348 from 350 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
87 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6592.954
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 87, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 6592.95402
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
If we divide 260 by 87, we get 2 and a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 6592.954022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 6592.954022 with a remainder of 8.6e-06.
