Let's divide 509670 by 99
We want to figure out the number of times 509670 can be divided by 99.

Let's proceed to step 1:
5 divided by 99 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 99

Let's proceed to step 2:
When dividing 50 by 99, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 99

Moving on to step 3:
509 divided by 99 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 14 after subtracting 495 from 509.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 99

Advancing to step 4:
When dividing 146 by 99, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 47 after subtracting 99 from 146.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 99

Moving on to step 5:
477 divided by 99 is 4 with a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
If we take 396 away from 477, we end up with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 99

Moving on to step 6:
99 goes into 810 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 5148.0
If we subtract 792 from 810, we 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.

On to step 7:
99 can be fit into 180 1 times, resulting in a remainder of 81.
The next digit of our result is 1. 
Result so far: 5148.1
Subtracting 99 from 180 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 8:
When dividing 810 by 99, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 5148.18
Subtract 792 from 810 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.

Step 9:
The number 99 fits into 180 1 times, leaving a remainder of 81.
The next digit of our result is 1. 
Result so far: 5148.181
Subtract 99 from 180 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 10:
99 can be fit into 810 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 5148.1818
The remainder is 18 after subtracting 792 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
The number 99 fits into 180 1 times, leaving a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 5148.18181
The remainder is 81 after subtracting 99 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 12:
99 can be fit into 810 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 5148.181818
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
If we divide 180 by 99, we get 1 and a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 5148.1818181
The remainder is 81 after subtracting 99 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 14:
The number 99 fits into 810 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 5148.18181818
Subtracting 792 from 810 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 5148.18181818 with a remaining 1.8e-08.
