We look at the division of 90878840 by 448 
We want to figure out the number of times 90878840 can be divided by 448.

Moving on to step 1:
9 divided by 448 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 448

Advancing to step 2:
When dividing 90 by 448, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 448

Step 3:
448 goes into 908 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 896 from 908 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 448

Going ahead to step 4:
127 divided by 448 is 0 with a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 127 leaves us with 127.
Grab the next digit (8) from the dividend, add it to 127, then carry on: 1278 / 448

On to step 5:
The number 448 fits into 1278 2 times, leaving a remainder of 382.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Subtracting 896 from 1278 leaves us with 382.
Append the next digit (8) from the dividend to 382 and continue with: 3828 / 448

Advancing to step 6:
448 goes into 3828 8 times with a remainder of 244.
Record the quotient 8 as the next digit in the result. 
Result so far: 2028.0
If we subtract 3584 from 3828, we get 244.
Append the next digit (4) from the dividend to 244 and continue with: 2444 / 448

Let's proceed to step 7:
448 goes into 2444 5 times with a remainder of 204.
The next digit of our result is 5. 
Result so far: 20285.0
Subtracting 2240 from 2444 leaves us with 204.
Grab the next digit (0) from the dividend, add it to 204, then carry on: 2040 / 448

On to step 8:
If we divide 2040 by 448, we get 4 and a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 202854.0
Subtract 1792 from 2040 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 9:
2480 divided by 448 is 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 202854.5
If we subtract 2240 from 2480, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
When dividing 2400 by 448, we get 5 with a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 202854.55
Subtracting 2240 from 2400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 202854.55 with a remainder of 0.16.
