We're dividing 91005129 by 448 
Let's see how many times 448 fits into 91005129.

Step 1:
The number 448 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 448

Moving on to step 2:
448 can be fit into 91 0 times, resulting in a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 448

Advancing to step 3:
448 goes into 910 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 896 away from 910, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 448

On to step 4:
The number 448 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 140, we end up with 140.
Grab the next digit (5) from the dividend, add it to 140, then carry on: 1405 / 448

Going ahead to step 5:
1405 divided by 448 is 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 203.0
The remainder is 61 after subtracting 1344 from 1405.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 448

Moving on to step 6:
448 can be fit into 611 1 times, resulting in a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 2031.0
If we take 448 away from 611, we end up with 163.
Bring next digit (2) of the dividend behind the 163 and repeat the process: 1632 / 448

Let's proceed to step 7:
If we divide 1632 by 448, we get 3 and a remainder of 288.
Use 3 as the next digit of our solution. 
Result so far: 20313.0
If we take 1344 away from 1632, we end up with 288.
Grab the next digit (9) from the dividend, add it to 288, then carry on: 2889 / 448

Let's proceed to step 8:
If we divide 2889 by 448, we get 6 and a remainder of 201.
The next digit of our result is 6. 
Result so far: 203136.0
If we subtract 2688 from 2889, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 9:
When dividing 2010 by 448, we get 4 with a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 203136.4
If we subtract 1792 from 2010, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 10:
When dividing 2180 by 448, we get 4 with a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 203136.44
The remainder is 388 after subtracting 1792 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 203136.44, with a leftover of 0.388.
