90131781 ÷ 448 
Let's see how many times 448 fits into 90131781.

Advancing to step 1:
If we divide 9 by 448, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 448

Let's proceed to step 2:
448 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 448

Step 3:
The number 448 fits into 901 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 896 from 901, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 448

Moving on to step 4:
448 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 53 to get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 448

Step 5:
If we divide 531 by 448, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
Subtracting 448 from 531 leaves us with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 448

Moving on to step 6:
If we divide 837 by 448, we get 1 and a remainder of 389.
Write down 1 as next digit of the result. 
Result so far: 2011.0
If we subtract 448 from 837, we get 389.
Take the next digit (8) from the dividend and append it to 389, then repeat: 3898 / 448

Moving on to step 7:
3898 divided by 448 is 8 with a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 20118.0
If we subtract 3584 from 3898, we get 314.
Append the next digit (1) from the dividend to 314 and continue with: 3141 / 448

Advancing to step 8:
448 can be fit into 3141 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 201187.0
Deduct 3136 from 3141 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 448 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 201187.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 448, we get 1 and a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 201187.01
Deduct 448 from 500 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
448 goes into 520 1 times with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 201187.011
The remainder is 72 after subtracting 448 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 201187.011 with a remainder of 0.0072.
