864287 divided by 57 
The aim is to understand the frequency of 57 in 864287.

Advancing to step 1:
57 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 57

Let's proceed to step 2:
When dividing 86 by 57, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 86, we get 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 57

Going ahead to step 3:
57 goes into 294 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 285 from 294 and we're left with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 57

Moving on to step 4:
When dividing 92 by 57, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 151.0
The remainder is 35 after subtracting 57 from 92.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 57

Step 5:
57 can be fit into 358 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1516.0
If we take 342 away from 358, we end up with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 57

Advancing to step 6:
167 divided by 57 is 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 15162.0
If we take 114 away from 167, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
The number 57 fits into 530 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 15162.9
The remainder is 17 after subtracting 513 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
57 goes into 170 2 times with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 15162.92
If we subtract 114 from 170, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
When dividing 560 by 57, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 15162.929
If we subtract 513 from 560, we 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.

Let's proceed to step 10:
If we divide 470 by 57, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 15162.9298
Subtracting 456 from 470 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.

Let's proceed to step 11:
The number 57 fits into 140 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 15162.92982
The remainder is 26 after subtracting 114 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 57 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 15162.929824
Subtracting 228 from 260 leaves us 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.

On to step 13:
57 goes into 320 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 15162.9298245
If we subtract 285 from 320, we 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.

Let's proceed to step 14:
57 can be fit into 350 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 15162.92982456
If we take 342 away from 350, 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.

In conclusion, the division gives 15162.92982456 with a balance of 8e-09.
