We divide 91782857 by 448
We want to figure out the number of times 91782857 can be divided by 448.

Let's proceed to step 1:
When dividing 9 by 448, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 448

On to step 2:
If we divide 91 by 448, we get 0 and a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (7) from the dividend to 91 and continue with: 917 / 448

Moving on to step 3:
917 divided by 448 is 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 896 from 917 to get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 448

Moving on to step 4:
448 can be fit into 218 0 times, resulting in a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 218 after subtracting 0 from 218.
Take the next digit (2) from the dividend and append it to 218, then repeat: 2182 / 448

Going ahead to step 5:
If we divide 2182 by 448, we get 4 and a remainder of 390.
Put 4 as the next digit of the answer. 
Result so far: 204.0
Subtracting 1792 from 2182 leaves us with 390.
Take the next digit (8) from the dividend and append it to 390, then repeat: 3908 / 448

On to step 6:
If we divide 3908 by 448, we get 8 and a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 2048.0
If we subtract 3584 from 3908, we get 324.
Append the next digit (5) from the dividend to 324 and continue with: 3245 / 448

Step 7:
If we divide 3245 by 448, we get 7 and a remainder of 109.
Write down 7 as next digit of the result. 
Result so far: 20487.0
If we subtract 3136 from 3245, we get 109.
Bring next digit (7) of the dividend behind the 109 and repeat the process: 1097 / 448

Let's proceed to step 8:
1097 divided by 448 is 2 with a remainder of 201.
Write down 2 as next digit of the result. 
Result so far: 204872.0
Deduct 896 from 1097 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 9:
448 goes into 2010 4 times with a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 204872.4
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.

Moving on to step 10:
If we divide 2180 by 448, we get 4 and a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 204872.44
Subtract 1792 from 2180 to get 388.
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 result is 204872.44 with a remainder of 0.388.
