We're dividing 402150 by 9 
Let's see how many times 9 fits into 402150.

Going ahead to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 9

Advancing to step 2:
40 divided by 9 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 36 from 40 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 9

On to step 3:
If we divide 42 by 9, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 6 after subtracting 36 from 42.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 9

Advancing to step 4:
61 divided by 9 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 446.0
The remainder is 7 after subtracting 54 from 61.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 9

Moving on to step 5:
75 divided by 9 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 4468.0
If we take 72 away from 75, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 9

Let's proceed to step 6:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 44683.0
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 44683.3
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
9 goes into 30 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 44683.33
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 44683.33, with a leftover of 0.003.
