526391 ÷ 15 
Our goal is to divide 526391 by 15.

Moving on to step 1:
If we divide 5 by 15, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 15

Advancing to step 2:
The number 15 fits into 52 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 45 from 52 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 15

Moving on to step 3:
When dividing 76 by 15, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we take 75 away from 76, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 15

Step 4:
The number 15 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 350.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 15

Going ahead to step 5:
15 can be fit into 139 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 3509.0
Subtracting 135 from 139 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 15

Going ahead to step 6:
15 can be fit into 41 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 35092.0
If we subtract 30 from 41, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
15 can be fit into 110 7 times, resulting in a remainder of 5.
The next digit of our result is 7. 
Result so far: 35092.7
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 35092.73
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 35092.733
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 35092.733 and a remainder of 0.0005.
