Let's divide 8428 by 9
We want to figure out the number of times 8428 can be divided by 9.

Advancing to step 1:
9 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 9

Let's proceed to step 2:
84 divided by 9 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 81 from 84, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 9

Going ahead to step 3:
9 can be fit into 32 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 27 away from 32, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 9

Going ahead to step 4:
If we divide 58 by 9, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 936.0
If we take 54 away from 58, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 5:
If we divide 40 by 9, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 936.4
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
When dividing 40 by 9, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 936.44
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 936.44 with a balance of 0.004.
