405828 divided by 87 
We want to figure out the number of times 405828 can be divided by 87.

Going ahead to step 1:
The number 87 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 87

Step 2:
When dividing 40 by 87, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 87

Let's proceed to step 3:
405 divided by 87 is 4 with a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 348 away from 405, we end up with 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 87

Let's proceed to step 4:
578 divided by 87 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 56 after subtracting 522 from 578.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 87

Let's proceed to step 5:
When dividing 562 by 87, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 466.0
Subtract 522 from 562 to get 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 87

Let's proceed to step 6:
408 divided by 87 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 4664.0
Subtract 348 from 408 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
If we divide 600 by 87, we get 6 and a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 4664.6
Subtract 522 from 600 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 8:
When dividing 780 by 87, we get 8 with a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 4664.68
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
When dividing 840 by 87, we get 9 with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 4664.689
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
If we divide 570 by 87, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 4664.6896
Subtracting 522 from 570 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
87 goes into 480 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4664.68965
Subtract 435 from 480 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
When dividing 450 by 87, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4664.689655
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 4664.689655 and a remainder of 1.5e-06.
