We look at the division of 27998217 by 90 
Let's see how many times 90 fits into 27998217.

Step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 90

Moving on to step 2:
27 divided by 90 is 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 90

Step 3:
90 can be fit into 279 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 270 from 279, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 90

Going ahead to step 4:
The number 90 fits into 99 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 90 from 99 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 90

Step 5:
90 goes into 98 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
Subtracting 90 from 98 leaves us with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 90

Let's proceed to step 6:
When dividing 82 by 90, we get 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 3110.0
Subtracting 0 from 82 leaves us with 82.
Append the next digit (1) from the dividend to 82 and continue with: 821 / 90

Let's proceed to step 7:
The number 90 fits into 821 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 31109.0
Deduct 810 from 821 and we're left with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 90

Let's proceed to step 8:
90 goes into 117 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 311091.0
Subtracting 90 from 117 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
90 goes into 270 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 311091.3
If we take 270 away from 270, 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.

Going ahead to step 10:
If we divide 0 by 90, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 311091.3
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.

Moving on to step 11:
When dividing 0 by 90, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 311091.3
Subtracting 0 from 0 leaves us 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.

Our division results in 311091.3 with a remaining 0.0.
