We look at the division of 864487 by 57 
Our goal is to divide 864487 by 57.

Going ahead 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
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 57

Advancing to step 2:
57 can be fit into 86 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 86 and we're left with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 57

Step 3:
294 divided by 57 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 285 away from 294, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 57

On to step 4:
57 goes into 94 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we take 57 away from 94, we end up with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 57

Step 5:
The number 57 fits into 378 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1516.0
Subtracting 342 from 378 leaves us with 36.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 57

Moving on to step 6:
If we divide 367 by 57, we get 6 and a remainder of 25.
The next digit of our result is 6. 
Result so far: 15166.0
Subtract 342 from 367 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
57 goes into 250 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 15166.4
Subtracting 228 from 250 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
The number 57 fits into 220 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 15166.43
Deduct 171 from 220 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
The number 57 fits into 490 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 15166.438
Deduct 456 from 490 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
When dividing 340 by 57, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 15166.4385
Deduct 285 from 340 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
If we divide 550 by 57, we get 9 and a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 15166.43859
The remainder is 37 after subtracting 513 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
When dividing 370 by 57, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 15166.438596
Subtracting 342 from 370 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
57 can be fit into 280 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 15166.4385964
If we subtract 228 from 280, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
The number 57 fits into 520 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 15166.43859649
Subtracting 513 from 520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 15166.43859649 and a remainder of 7e-09.
