We look at the division of 87559021 by 526 
We're looking to find how many times 526 goes into 87559021.

Step 1:
The number 526 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 526

Advancing to step 2:
When dividing 87 by 526, we get 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (5) from the dividend, add it to 87, then carry on: 875 / 526

Advancing to step 3:
526 goes into 875 1 times with a remainder of 349.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 526 from 875 and we're left with 349.
Include the next digit (5) from the dividend after 349, then repeat: 3495 / 526

Advancing to step 4:
526 can be fit into 3495 6 times, resulting in a remainder of 339.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 3156 from 3495 and we're left with 339.
Bring next digit (9) of the dividend behind the 339 and repeat the process: 3399 / 526

Step 5:
When dividing 3399 by 526, we get 6 with a remainder of 243.
Use 6 as the next digit of our solution. 
Result so far: 166.0
If we take 3156 away from 3399, we end up with 243.
Take the next digit (0) from the dividend and append it to 243, then repeat: 2430 / 526

On to step 6:
526 goes into 2430 4 times with a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 1664.0
If we take 2104 away from 2430, we end up with 326.
Include the next digit (2) from the dividend after 326, then repeat: 3262 / 526

Step 7:
When dividing 3262 by 526, we get 6 with a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 16646.0
Deduct 3156 from 3262 and we're left with 106.
Fetch the next digit (1) from the dividend, attach it to 106 and continue: 1061 / 526

On to step 8:
1061 divided by 526 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 166462.0
If we subtract 1052 from 1061, we get 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 9:
526 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 166462.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
526 can be fit into 900 1 times, resulting in a remainder of 374.
The next digit of our result is 1. 
Result so far: 166462.01
If we take 526 away from 900, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 11:
The number 526 fits into 3740 7 times, leaving a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 166462.017
If we subtract 3682 from 3740, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
526 can be fit into 580 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 166462.0171
If we take 526 away from 580, 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.

Step 13:
If we divide 540 by 526, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 166462.01711
If we take 526 away from 540, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 166462.01711 with a remaining 1.4e-05.
