Let's divide 6428 by 90
Our goal is to divide 6428 by 90.

Moving on to step 1:
If we divide 6 by 90, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 90

Advancing to step 2:
When dividing 64 by 90, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 90

On to step 3:
90 can be fit into 642 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 12 after subtracting 630 from 642.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 90

Step 4:
When dividing 128 by 90, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 90 from 128, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 5:
90 can be fit into 380 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 71.4
If we subtract 360 from 380, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 6:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 71.42
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
90 goes into 200 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 71.422
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 71.422, and the remainder is 0.002.
