We're dividing 366422 by 90 
We're looking to find how many times 90 goes into 366422.

Step 1:
The number 90 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 90

Moving on to step 2:
The number 90 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 90

Advancing to step 3:
366 divided by 90 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 360 from 366 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 90

Let's proceed to step 4:
90 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 90

Let's proceed to step 5:
642 divided by 90 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 407.0
Subtracting 630 from 642 leaves us with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 90

Going ahead to step 6:
90 goes into 122 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 4071.0
Deduct 90 from 122 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
If we divide 320 by 90, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 4071.3
If we subtract 270 from 320, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 90, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4071.35
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
500 divided by 90 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4071.355
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 4071.355, and the remainder is 0.005.
