438489 divided by 87 
Let's see how many times 87 fits into 438489.

Step 1:
If we divide 4 by 87, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 87

Moving on to step 2:
87 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 87

Moving on to step 3:
If we divide 438 by 87, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 435 away from 438, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 87

Advancing to step 4:
If we divide 34 by 87, we get 0 and a remainder of 34.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 34, we end up with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 87

Moving on to step 5:
348 divided by 87 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
The remainder is 0 after subtracting 348 from 348.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 87

Going ahead to step 6:
If we divide 9 by 87, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 5040.0
If we take 0 away from 9, we end up with 9.
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:
87 can be fit into 90 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 5040.1
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.

On to step 8:
When dividing 30 by 87, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5040.1
Subtract 0 from 30 to get 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:
When dividing 300 by 87, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 5040.103
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.

On to step 10:
87 goes into 390 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 5040.1034
Subtracting 348 from 390 leaves us 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.

Advancing to step 11:
87 can be fit into 420 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 5040.10344
Subtract 348 from 420 to 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.

After the division, we end up with 5040.10344 and a remainder of 7.2e-05.
