We look at the division of 50870561 by 9 
We want to figure out the number of times 50870561 can be divided by 9.

On to step 1:
9 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 9

Moving on to step 2:
When dividing 50 by 9, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 45 from 50, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 9

On to step 3:
9 goes into 58 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we subtract 54 from 58, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 9

Step 4:
The number 9 fits into 47 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 565.0
Subtracting 45 from 47 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 9

On to step 5:
If we divide 20 by 9, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 5652.0
Subtracting 18 from 20 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 9

Going ahead to step 6:
25 divided by 9 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 56522.0
Subtracting 18 from 25 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 9

Let's proceed to step 7:
9 goes into 76 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 565228.0
The remainder is 4 after subtracting 72 from 76.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 9

Advancing to step 8:
If we divide 41 by 9, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 5652284.0
Subtract 36 from 41 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.

Moving on to step 9:
9 goes into 50 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5652284.5
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.

Going ahead to step 10:
50 divided by 9 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5652284.55
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 5652284.55 and a remainder of 0.005.
