284121 ÷ 90 
We're looking to find how many times 90 goes into 284121.

Advancing to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 90

Advancing to step 2:
When dividing 28 by 90, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 90

Going ahead to step 3:
284 divided by 90 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 270 away from 284, we end up with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 90

Let's proceed to step 4:
The number 90 fits into 141 1 times, leaving a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 90 from 141 and we're left with 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 90

On to step 5:
When dividing 512 by 90, we get 5 with a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Subtract 450 from 512 to get 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 90

Step 6:
If we divide 621 by 90, we get 6 and a remainder of 81.
Write down 6 as next digit of the result. 
Result so far: 3156.0
If we take 540 away from 621, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
If we divide 810 by 90, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 3156.9
The remainder is 0 after subtracting 810 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3156.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3156.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3156.9 with a remaining 0.0.
