We're dividing 216379 by 90 
Let's see how many times 90 fits into 216379.

Let's proceed to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 90

Going ahead to step 2:
90 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 90

Advancing to step 3:
The number 90 fits into 216 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 180 from 216 and we're left with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 90

On to step 4:
90 goes into 363 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 360 from 363 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 90

Going ahead to step 5:
37 divided by 90 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 240.0
If we take 0 away from 37, we end up with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 90

Advancing to step 6:
The number 90 fits into 379 4 times, leaving a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 2404.0
The remainder is 19 after subtracting 360 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 90, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2404.2
If we take 180 away from 190, we end up 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.

Step 8:
90 goes into 100 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 2404.21
Subtracting 90 from 100 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.

Moving on to step 9:
90 goes into 100 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 2404.211
The remainder is 10 after subtracting 90 from 100.
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 2404.211, and the remainder is 0.001.
