Let's divide 53431 by 9
Let's see how many times 9 fits into 53431.

Let's proceed 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
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 9

Moving on to step 2:
53 divided by 9 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 45 from 53, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 9

On to step 3:
84 divided by 9 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Deduct 81 from 84 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 9

Advancing to step 4:
9 goes into 33 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 593.0
Deduct 27 from 33 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 9

Advancing to step 5:
9 goes into 61 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 5936.0
If we take 54 away from 61, 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.

Let's proceed to step 6:
70 divided by 9 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 5936.7
Deduct 63 from 70 and we're left 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.

Going ahead to step 7:
70 divided by 9 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 5936.77
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 5936.77, with a leftover of 0.007.
