We're dividing 521561 by 9 
We're looking to find how many times 9 goes into 521561.

Going ahead to step 1:
9 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 9

Advancing to step 2:
The number 9 fits into 52 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 45 from 52 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 9

Advancing to step 3:
71 divided by 9 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 8 after subtracting 63 from 71.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 9

Moving on to step 4:
If we divide 85 by 9, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 579.0
Deduct 81 from 85 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 9

Moving on to step 5:
9 can be fit into 46 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 5795.0
The remainder is 1 after subtracting 45 from 46.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

On to step 6:
9 goes into 11 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 57951.0
If we subtract 9 from 11, we get 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 7:
9 goes into 20 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 57951.2
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 9 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 57951.22
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 57951.22 with a balance of 0.002.
