We look at the division of 857386 by 57 
Let's see how many times 57 fits into 857386.

Advancing to step 1:
8 divided by 57 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 57

Let's proceed to step 2:
85 divided by 57 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 57 from 85 to get 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 57

Let's proceed to step 3:
When dividing 287 by 57, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 285 from 287 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 57

Step 4:
The number 57 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we subtract 0 from 23, we get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 57

Moving on to step 5:
57 can be fit into 238 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1504.0
Subtracting 228 from 238 leaves us with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 57

Going ahead to step 6:
If we divide 106 by 57, we get 1 and a remainder of 49.
The next digit of our result is 1. 
Result so far: 15041.0
If we subtract 57 from 106, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
If we divide 490 by 57, we get 8 and a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 15041.8
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
When dividing 340 by 57, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 15041.85
Subtract 285 from 340 to get 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 9:
550 divided by 57 is 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 15041.859
If we subtract 513 from 550, we get 37.
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 10:
57 goes into 370 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 15041.8596
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
If we divide 280 by 57, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 15041.85964
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.

Step 12:
57 can be fit into 520 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 15041.859649
Deduct 513 from 520 and we're left 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.

Moving on to step 13:
70 divided by 57 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 15041.8596491
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
If we divide 130 by 57, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 15041.85964912
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 15041.85964912 with a balance of 1.6e-08.
