We divide 19736691 by 90
Let's see how many times 90 fits into 19736691.

Moving on to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 90

On to step 2:
90 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 90

Advancing to step 3:
90 goes into 197 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
If we take 180 away from 197, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 90

Step 4:
If we divide 173 by 90, we get 1 and a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 90 away from 173, we end up with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 90

Advancing to step 5:
The number 90 fits into 836 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 219.0
Deduct 810 from 836 and we're left with 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 90

Moving on to step 6:
If we divide 266 by 90, we get 2 and a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 2192.0
Subtracting 180 from 266 leaves us with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 90

Let's proceed to step 7:
90 goes into 869 9 times with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 21929.0
Subtracting 810 from 869 leaves us with 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 90

Going ahead to step 8:
90 can be fit into 591 6 times, resulting in a remainder of 51.
The next digit of our result is 6. 
Result so far: 219296.0
Deduct 540 from 591 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
90 goes into 510 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 219296.5
Subtracting 450 from 510 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.

Let's proceed to step 10:
The number 90 fits into 600 6 times, leaving a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 219296.56
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.

Going ahead to step 11:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 219296.566
Deduct 540 from 600 and we're left 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.

The quotient of the division is 219296.566, and the remainder is 0.006.
