Let's divide 339555 by 87
We're looking to find how many times 87 goes into 339555.

On to step 1:
If we divide 3 by 87, we get 0 and 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 (3) from the dividend and append it to 3, then repeat: 33 / 87

Advancing to step 2:
If we divide 33 by 87, we get 0 and 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.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 87

Let's proceed to step 3:
If we divide 339 by 87, we get 3 and a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 78 after subtracting 261 from 339.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 87

Going ahead to step 4:
785 divided by 87 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 783 from 785 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 87

Moving on to step 5:
When dividing 25 by 87, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 87

Step 6:
When dividing 255 by 87, we get 2 with a remainder of 81.
The next digit of our result is 2. 
Result so far: 3902.0
Subtracting 174 from 255 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.

Advancing to step 7:
87 can be fit into 810 9 times, resulting in a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 3902.9
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
When dividing 270 by 87, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 3902.93
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 87 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 3902.931
The remainder is 3 after subtracting 87 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
30 divided by 87 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 3902.931
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.

On to step 11:
87 can be fit into 300 3 times, resulting in a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 3902.93103
Subtracting 261 from 300 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
87 can be fit into 390 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 3902.931034
If we take 348 away from 390, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
87 goes into 420 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 3902.9310344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 3902.9310344 with a remaining 7.2e-07.
