We're dividing 19687452 by 90 
Our goal is to divide 19687452 by 90.

Step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 90

Let's proceed to step 2:
If we divide 19 by 90, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 90

On to step 3:
When dividing 196 by 90, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 180 from 196, we get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 90

On to step 4:
90 goes into 168 1 times with a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 90 from 168, we get 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 90

Step 5:
If we divide 787 by 90, we get 8 and a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 218.0
If we subtract 720 from 787, we get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 90

Step 6:
674 divided by 90 is 7 with a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 2187.0
If we take 630 away from 674, we end up with 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 90

Moving on to step 7:
445 divided by 90 is 4 with a remainder of 85.
Write down 4 as next digit of the result. 
Result so far: 21874.0
Subtract 360 from 445 to get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 90

On to step 8:
The number 90 fits into 852 9 times, leaving a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 218749.0
Subtract 810 from 852 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 90, we get 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 218749.4
Subtracting 360 from 420 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
600 divided by 90 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 218749.46
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
90 goes into 600 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 218749.466
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 218749.466 with a remaining 0.006.
