We're dividing 521435 by 9 
We want to divide 521435 by 9.

Let's proceed to step 1:
9 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 9

Moving on to step 2:
When dividing 52 by 9, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 45 from 52 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 9

Advancing to step 3:
If we divide 71 by 9, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 63 from 71 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 9

Let's proceed to step 4:
If we divide 84 by 9, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 579.0
If we take 81 away from 84, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 9

On to step 5:
If we divide 33 by 9, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 5793.0
Subtract 27 from 33 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 9

Advancing to step 6:
65 divided by 9 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 57937.0
If we take 63 away from 65, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 9, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 57937.2
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 9, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 57937.22
Subtract 18 from 20 to 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.

The final outcome is 57937.22, with a leftover of 0.002.
