We're dividing 339984 by 87 
Let's see how many times 87 fits into 339984.

Moving on to step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 87

Going ahead to step 2:
87 can be fit into 33 0 times, resulting in a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 87

Moving on to step 3:
339 divided by 87 is 3 with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 261 from 339 and we're left with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 87

Let's proceed to step 4:
789 divided by 87 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 783 from 789 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 87

Going ahead to step 5:
87 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 390.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 87

Let's proceed to step 6:
When dividing 684 by 87, we get 7 with a remainder of 75.
The next digit of our result is 7. 
Result so far: 3907.0
If we take 609 away from 684, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
When dividing 750 by 87, we get 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 3907.8
If we take 696 away from 750, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
540 divided by 87 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 3907.86
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
180 divided by 87 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 3907.862
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
If we divide 60 by 87, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 3907.862
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
87 goes into 600 6 times with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 3907.86206
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
87 can be fit into 780 8 times, resulting in a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 3907.862068
Subtract 696 from 780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
If we divide 840 by 87, we get 9 and a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 3907.8620689
Subtracting 783 from 840 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 14:
The number 87 fits into 570 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 3907.86206896
Deduct 522 from 570 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 3907.86206896 and a remainder of 4.8e-08.
