606857 divided by 87 
The aim is to understand the frequency of 87 in 606857.

Step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 87

Step 2:
When dividing 60 by 87, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 87

Let's proceed to step 3:
87 can be fit into 606 6 times, resulting in a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 522 from 606 leaves us with 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 87

Advancing to step 4:
87 can be fit into 848 9 times, resulting in a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtract 783 from 848 to get 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 87

Step 5:
87 goes into 655 7 times with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 697.0
If we take 609 away from 655, we end up with 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 87

Let's proceed to step 6:
When dividing 467 by 87, we get 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 6975.0
Deduct 435 from 467 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
87 can be fit into 320 3 times, resulting in a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 6975.3
If we subtract 261 from 320, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 8:
If we divide 590 by 87, we get 6 and a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 6975.36
Deduct 522 from 590 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
680 divided by 87 is 7 with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 6975.367
The remainder is 71 after subtracting 609 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
710 divided by 87 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 6975.3678
If we take 696 away from 710, we end up 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.

Let's proceed to step 11:
140 divided by 87 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 6975.36781
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.

Going ahead to step 12:
87 goes into 530 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6975.367816
If we take 522 away from 530, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
80 divided by 87 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 6975.367816
Deduct 0 from 80 and we're left 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.

Step 14:
87 goes into 800 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 6975.36781609
If we take 783 away from 800, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 6975.36781609, and the remainder is 1.7e-08.
