Let's divide 302455 by 90
We want to divide 302455 by 90.

On to step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 90

Let's proceed to step 2:
30 divided by 90 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 90

Going ahead to step 3:
When dividing 302 by 90, we get 3 with a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 270 from 302 and we're left with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 90

Advancing to step 4:
If we divide 324 by 90, we get 3 and a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 54 after subtracting 270 from 324.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 90

Let's proceed to step 5:
The number 90 fits into 545 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 336.0
Deduct 540 from 545 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 90

Going ahead to step 6:
90 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 3360.0
If we take 0 away from 55, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
When dividing 550 by 90, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 3360.6
If we subtract 540 from 550, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 3360.61
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 3360.611
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 3360.611, and the remainder is 0.001.
