We look at the division of 51857 by 60 
We're looking to find how many times 60 goes into 51857.

Let's proceed to step 1:
The number 60 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 60

Going ahead to step 2:
If we divide 51 by 60, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 60

Advancing to step 3:
If we divide 518 by 60, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 480 from 518 to get 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 60

Moving on to step 4:
When dividing 385 by 60, we get 6 with a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 25 after subtracting 360 from 385.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 60

Let's proceed to step 5:
257 divided by 60 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 864.0
Subtract 240 from 257 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 6:
60 goes into 170 2 times with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 864.2
The remainder is 50 after subtracting 120 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
If we divide 500 by 60, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 864.28
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
The number 60 fits into 200 3 times, leaving a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 864.283
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 60 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 864.2833
Subtract 180 from 200 to 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.

The final result is 864.2833 with a remainder of 0.0002.
