388615 ÷ 87 
We want to figure out the number of times 388615 can be divided by 87.

Step 1:
3 divided by 87 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 87

Let's proceed to step 2:
If we divide 38 by 87, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 87

Step 3:
87 goes into 388 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 40 after subtracting 348 from 388.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 87

Advancing to step 4:
When dividing 406 by 87, we get 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 348 from 406 leaves us with 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 87

Going ahead to step 5:
When dividing 581 by 87, we get 6 with a remainder of 59.
Write down 6 as next digit of the result. 
Result so far: 446.0
Deduct 522 from 581 and we're left with 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 87

On to step 6:
The number 87 fits into 595 6 times, leaving a remainder of 73.
Use 6 as the next digit of our solution. 
Result so far: 4466.0
Subtract 522 from 595 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
87 goes into 730 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 4466.8
The remainder is 34 after subtracting 696 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
When dividing 340 by 87, we get 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 4466.83
Deduct 261 from 340 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
If we divide 790 by 87, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 4466.839
Deduct 783 from 790 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
70 divided by 87 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4466.839
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
If we divide 700 by 87, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 4466.83908
If we take 696 away from 700, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
If we divide 40 by 87, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4466.83908
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
When dividing 400 by 87, we get 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 4466.8390804
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
The number 87 fits into 520 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 4466.83908045
Subtract 435 from 520 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 4466.83908045 with a remainder of 8.5e-08.
