384639 ÷ 87 
Our goal is to divide 384639 by 87.

Let's proceed to step 1:
87 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 87

On to step 2:
When dividing 38 by 87, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 87

Step 3:
If we divide 384 by 87, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 348 from 384, we get 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 87

On to step 4:
87 can be fit into 366 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 18 after subtracting 348 from 366.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 87

Step 5:
If we divide 183 by 87, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
Deduct 174 from 183 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 87

On to step 6:
The number 87 fits into 99 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 4421.0
The remainder is 12 after subtracting 87 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 87 is 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 4421.1
If we take 87 away from 120, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
When dividing 330 by 87, we get 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 4421.13
Subtracting 261 from 330 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
690 divided by 87 is 7 with a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 4421.137
Subtracting 609 from 690 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 10:
When dividing 810 by 87, we get 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 4421.1379
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
270 divided by 87 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 4421.13793
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
When dividing 90 by 87, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4421.137931
Deduct 87 from 90 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4421.137931
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
When dividing 300 by 87, we get 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 4421.13793103
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 4421.13793103 and a remainder of 3.9e-08.
