We look at the division of 57275787 by 387 
We want to divide 57275787 by 387.

Step 1:
When dividing 5 by 387, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 387

Advancing to step 2:
57 divided by 387 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 387

Going ahead to step 3:
572 divided by 387 is 1 with a remainder of 185.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 387 from 572 to get 185.
Bring next digit (7) of the dividend behind the 185 and repeat the process: 1857 / 387

Going ahead to step 4:
1857 divided by 387 is 4 with a remainder of 309.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 1548 from 1857 to get 309.
Append the next digit (5) from the dividend to 309 and continue with: 3095 / 387

Let's proceed to step 5:
387 goes into 3095 7 times with a remainder of 386.
Use 7 as the next digit of our solution. 
Result so far: 147.0
If we take 2709 away from 3095, we end up with 386.
Fetch the next digit (7) from the dividend, attach it to 386 and continue: 3867 / 387

Moving on to step 6:
3867 divided by 387 is 9 with a remainder of 384.
Write down 9 as next digit of the result. 
Result so far: 1479.0
If we take 3483 away from 3867, we end up with 384.
Append the next digit (8) from the dividend to 384 and continue with: 3848 / 387

Let's proceed to step 7:
When dividing 3848 by 387, we get 9 with a remainder of 365.
Put 9 as the next digit of the answer. 
Result so far: 14799.0
The remainder is 365 after subtracting 3483 from 3848.
Bring next digit (7) of the dividend behind the 365 and repeat the process: 3657 / 387

Moving on to step 8:
387 goes into 3657 9 times with a remainder of 174.
The next digit of our result is 9. 
Result so far: 147999.0
Deduct 3483 from 3657 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 9:
When dividing 1740 by 387, we get 4 with a remainder of 192.
Write down 4 as next digit of the result. 
Result so far: 147999.4
The remainder is 192 after subtracting 1548 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 10:
1920 divided by 387 is 4 with a remainder of 372.
Put 4 as the next digit of the answer. 
Result so far: 147999.44
Subtract 1548 from 1920 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 147999.44 and a remainder of 0.372.
