448777 ÷ 90 
We want to figure out the number of times 448777 can be divided by 90.

Moving on to step 1:
4 divided by 90 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 90

Moving on to step 2:
The number 90 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 90

On to step 3:
90 can be fit into 448 4 times, resulting in a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 360 from 448 to get 88.
Grab the next digit (7) from the dividend, add it to 88, then carry on: 887 / 90

On to step 4:
90 can be fit into 887 9 times, resulting in a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 810 from 887 leaves us with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 90

Advancing to step 5:
The number 90 fits into 777 8 times, leaving a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 498.0
The remainder is 57 after subtracting 720 from 777.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 90

Step 6:
90 goes into 577 6 times with a remainder of 37.
The next digit of our result is 6. 
Result so far: 4986.0
If we subtract 540 from 577, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
The number 90 fits into 370 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 4986.4
If we subtract 360 from 370, 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.

Moving on to step 8:
If we divide 100 by 90, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 4986.41
Subtract 90 from 100 to 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.

Going ahead to step 9:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 4986.411
If we take 90 away from 100, 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.

The final result is 4986.411 with a remainder of 0.001.
