We divide 528405 by 87
We want to figure out the number of times 528405 can be divided by 87.

On to step 1:
The number 87 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 87

Going ahead to step 2:
87 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 87

Let's proceed to step 3:
87 goes into 528 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 522 from 528 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 87

Going ahead to step 4:
The number 87 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtract 0 from 64 to get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 87

Advancing to step 5:
640 divided by 87 is 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 607.0
If we take 609 away from 640, we end up with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 87

Moving on to step 6:
315 divided by 87 is 3 with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 6073.0
Deduct 261 from 315 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
540 divided by 87 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 6073.6
The remainder is 18 after subtracting 522 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 87, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 6073.62
If we subtract 174 from 180, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 87, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 6073.62
Subtract 0 from 60 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.

On to step 10:
If we divide 600 by 87, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 6073.6206
If we subtract 522 from 600, we 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.

Step 11:
87 can be fit into 780 8 times, resulting in a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 6073.62068
If we subtract 696 from 780, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
When dividing 840 by 87, we get 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 6073.620689
If we subtract 783 from 840, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
87 can be fit into 570 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 6073.6206896
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.

Let's proceed to step 14:
87 goes into 480 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6073.62068965
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 6073.62068965 with a balance of 4.5e-08.
