57315028 divided by 387 
Let's see how many times 387 fits into 57315028.

On to step 1:
The number 387 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 387

Moving on to step 2:
387 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 387

Going ahead to step 3:
387 can be fit into 573 1 times, resulting in a remainder of 186.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 387 from 573 and we're left with 186.
Grab the next digit (1) from the dividend, add it to 186, then carry on: 1861 / 387

Advancing to step 4:
1861 divided by 387 is 4 with a remainder of 313.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 1548 from 1861 and we're left with 313.
Grab the next digit (5) from the dividend, add it to 313, then carry on: 3135 / 387

On to step 5:
The number 387 fits into 3135 8 times, leaving a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 148.0
Deduct 3096 from 3135 and we're left with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 387

Moving on to step 6:
The number 387 fits into 390 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1481.0
If we take 387 away from 390, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 387

Moving on to step 7:
32 divided by 387 is 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 14810.0
If we take 0 away from 32, we end up with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 387

Moving on to step 8:
387 can be fit into 328 0 times, resulting in a remainder of 328.
Put 0 as the next digit of the answer. 
Result so far: 148100.0
If we take 0 away from 328, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 9:
387 goes into 3280 8 times with a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 148100.8
Deduct 3096 from 3280 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
The number 387 fits into 1840 4 times, leaving a remainder of 292.
Record the quotient 4 as the next digit in the result. 
Result so far: 148100.84
Deduct 1548 from 1840 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 11:
If we divide 2920 by 387, we get 7 and a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 148100.847
If we subtract 2709 from 2920, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 12:
2110 divided by 387 is 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 148100.8475
Subtract 1935 from 2110 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 13:
The number 387 fits into 1750 4 times, leaving a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 148100.84754
Deduct 1548 from 1750 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 14:
If we divide 2020 by 387, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 148100.847545
If we take 1935 away from 2020, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 15:
387 can be fit into 850 2 times, resulting in a remainder of 76.
The next digit of our result is 2. 
Result so far: 148100.8475452
If we subtract 774 from 850, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 16:
If we divide 760 by 387, we get 1 and a remainder of 373.
Use 1 as the next digit of our solution. 
Result so far: 148100.84754521
Deduct 387 from 760 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

After the division, we end up with 148100.84754521 and a remainder of 3.73e-07.
