298216 ÷ 90 
We're looking to find how many times 90 goes into 298216.

Going ahead to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 90

Step 2:
90 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 90

Step 3:
If we divide 298 by 90, we get 3 and a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 270 from 298 to get 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 90

Moving on to step 4:
When dividing 282 by 90, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtracting 270 from 282 leaves us with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 90

Advancing to step 5:
When dividing 121 by 90, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 331.0
If we subtract 90 from 121, we get 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 90

On to step 6:
90 goes into 316 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 3313.0
The remainder is 46 after subtracting 270 from 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
When dividing 460 by 90, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3313.5
Subtracting 450 from 460 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 90 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 3313.51
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:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 3313.511
Subtract 90 from 100 to 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 final outcome is 3313.511, with a leftover of 0.001.
