We're dividing 528509 by 42 
We're looking to find how many times 42 goes into 528509.

On to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 42

Advancing to step 2:
52 divided by 42 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 42 from 52, we get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 42

Step 3:
42 can be fit into 108 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 84 away from 108, we end up with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 42

Let's proceed to step 4:
If we divide 245 by 42, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 125.0
Deduct 210 from 245 and we're left with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 42

On to step 5:
If we divide 350 by 42, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1258.0
Subtract 336 from 350 to get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 42

Moving on to step 6:
If we divide 149 by 42, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 12583.0
Subtracting 126 from 149 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
42 can be fit into 230 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 12583.5
Subtracting 210 from 230 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 12583.54
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
42 goes into 320 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 12583.547
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
42 goes into 260 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 12583.5476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 12583.54761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
380 divided by 42 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 12583.547619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12583.547619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
42 goes into 200 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 12583.54761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 12583.54761904, and the remainder is 3.2e-08.
