519172 ÷ 9 
We're looking to find how many times 9 goes into 519172.

On to step 1:
The number 9 fits into 5 0 times, leaving 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 (1) from the dividend to 5 and continue with: 51 / 9

Let's proceed to step 2:
If we divide 51 by 9, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 45 away from 51, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

Moving on to step 3:
9 can be fit into 69 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 57.0
If we take 63 away from 69, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 9

Advancing to step 4:
9 can be fit into 61 6 times, resulting in a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 576.0
If we take 54 away from 61, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 9

Moving on to step 5:
77 divided by 9 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 5768.0
If we take 72 away from 77, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 9

Let's proceed to step 6:
9 can be fit into 52 5 times, resulting in a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 57685.0
If we take 45 away from 52, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 9 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 57685.7
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 57685.77
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 57685.77 with a remaining 0.007.
