We look at the division of 18821229 by 387 
Let's see how many times 387 fits into 18821229.

Moving on to step 1:
If we divide 1 by 387, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 387

Going ahead to step 2:
If we divide 18 by 387, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 387

Advancing to step 3:
The number 387 fits into 188 0 times, leaving a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Bring next digit (2) of the dividend behind the 188 and repeat the process: 1882 / 387

Step 4:
If we divide 1882 by 387, we get 4 and a remainder of 334.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 1548 from 1882 leaves us with 334.
Fetch the next digit (1) from the dividend, attach it to 334 and continue: 3341 / 387

Going ahead to step 5:
387 can be fit into 3341 8 times, resulting in a remainder of 245.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 3096 from 3341 to get 245.
Take the next digit (2) from the dividend and append it to 245, then repeat: 2452 / 387

Moving on to step 6:
387 can be fit into 2452 6 times, resulting in a remainder of 130.
The number 6 becomes the next digit in our result. 
Result so far: 486.0
Deduct 2322 from 2452 and we're left with 130.
Append the next digit (2) from the dividend to 130 and continue with: 1302 / 387

Let's proceed to step 7:
387 can be fit into 1302 3 times, resulting in a remainder of 141.
Record the quotient 3 as the next digit in the result. 
Result so far: 4863.0
Subtract 1161 from 1302 to get 141.
Bring next digit (9) of the dividend behind the 141 and repeat the process: 1419 / 387

Let's proceed to step 8:
If we divide 1419 by 387, we get 3 and a remainder of 258.
The next digit of our result is 3. 
Result so far: 48633.0
Subtracting 1161 from 1419 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 9:
387 can be fit into 2580 6 times, resulting in a remainder of 258.
Put 6 as the next digit of the answer. 
Result so far: 48633.6
Subtract 2322 from 2580 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
When dividing 2580 by 387, we get 6 with a remainder of 258.
The number 6 becomes the next digit in our result. 
Result so far: 48633.66
The remainder is 258 after subtracting 2322 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The quotient of the division is 48633.66, and the remainder is 0.258.
