378285 ÷ 87 
We want to divide 378285 by 87.

On to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 87

Let's proceed to step 2:
When dividing 37 by 87, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 87

On to step 3:
87 goes into 378 4 times with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 30 after subtracting 348 from 378.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 87

Let's proceed to step 4:
If we divide 302 by 87, we get 3 and a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 41 after subtracting 261 from 302.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 87

Let's proceed to step 5:
87 can be fit into 418 4 times, resulting in a remainder of 70.
The next digit of our result is 4. 
Result so far: 434.0
If we take 348 away from 418, we end up with 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 87

Going ahead to step 6:
87 goes into 705 8 times with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 4348.0
The remainder is 9 after subtracting 696 from 705.
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 7:
The number 87 fits into 90 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 4348.1
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.

Let's proceed to step 8:
87 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4348.1
The remainder is 30 after subtracting 0 from 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 9:
87 goes into 300 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 4348.103
If we take 261 away from 300, we end up 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 10:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4348.1034
The remainder is 42 after subtracting 348 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
420 divided by 87 is 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 4348.10344
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.

In conclusion, the division gives 4348.10344 with a balance of 7.2e-05.
