We look at the division of 50408776 by 90 
We're looking to find how many times 90 goes into 50408776.

Step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 90

Moving on to step 2:
90 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 90

Going ahead to step 3:
90 can be fit into 504 5 times, resulting in a remainder of 54.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 450 from 504 leaves us with 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 90

Moving on to step 4:
The number 90 fits into 540 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Subtracting 540 from 540 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 90

Step 5:
When dividing 8 by 90, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 560.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 90

Let's proceed to step 6:
87 divided by 90 is 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 5600.0
Subtract 0 from 87 to get 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 90

Moving on to step 7:
When dividing 877 by 90, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 56009.0
If we take 810 away from 877, we end up with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 90

Going ahead to step 8:
If we divide 676 by 90, we get 7 and a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 560097.0
If we take 630 away from 676, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
90 goes into 460 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 560097.5
If we subtract 450 from 460, 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.

Advancing to step 10:
90 goes into 100 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 560097.51
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.

Let's proceed to step 11:
When dividing 100 by 90, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 560097.511
Deduct 90 from 100 and we're left 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.

The quotient of the division is 560097.511, and the remainder is 0.001.
