We look at the division of 528591 by 87 
We want to figure out the number of times 528591 can be divided by 87.

Let's proceed to step 1:
87 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 87

Step 2:
When dividing 52 by 87, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 87

Going ahead to step 3:
87 goes into 528 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 522 from 528, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 87

Advancing to step 4:
If we divide 65 by 87, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 60.0
Subtracting 0 from 65 leaves us with 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 87

Advancing to step 5:
The number 87 fits into 659 7 times, leaving a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 607.0
Subtract 609 from 659 to get 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 87

Moving on to step 6:
87 can be fit into 501 5 times, resulting in a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 6075.0
Subtract 435 from 501 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
87 goes into 660 7 times with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 6075.7
If we subtract 609 from 660, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 8:
510 divided by 87 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 6075.75
The remainder is 75 after subtracting 435 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
87 can be fit into 750 8 times, resulting in a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 6075.758
If we take 696 away from 750, we end up 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.

Going ahead to step 10:
When dividing 540 by 87, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 6075.7586
Subtract 522 from 540 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
The number 87 fits into 180 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 6075.75862
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
87 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 6075.75862
If we subtract 0 from 60, we 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.

Let's proceed to step 13:
The number 87 fits into 600 6 times, leaving a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 6075.7586206
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
87 can be fit into 780 8 times, resulting in a remainder of 84.
The next digit of our result is 8. 
Result so far: 6075.75862068
If we take 696 away from 780, we end up 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.

After the division, we end up with 6075.75862068 and a remainder of 8.4e-08.
