320624 divided by 87 
Let's see how many times 87 fits into 320624.

Moving on to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 87

Going ahead to step 2:
87 can be fit into 32 0 times, resulting in a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 87

Step 3:
If we divide 320 by 87, we get 3 and a remainder of 59.
The next digit of our result is 3. 
Result so far: 3.0
If we take 261 away from 320, we end up with 59.
Grab the next digit (6) from the dividend, add it to 59, then carry on: 596 / 87

On to step 4:
If we divide 596 by 87, we get 6 and a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 74 after subtracting 522 from 596.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 87

Step 5:
The number 87 fits into 742 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 368.0
Deduct 696 from 742 and we're left with 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 87

Advancing to step 6:
87 goes into 464 5 times with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 3685.0
Subtracting 435 from 464 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
290 divided by 87 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 3685.3
Subtracting 261 from 290 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
If we divide 290 by 87, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 3685.33
Subtracting 261 from 290 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 3685.33 with a remainder of 0.029.
