We divide 90121577 by 448
We want to divide 90121577 by 448.

On to step 1:
The number 448 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 448

Moving on to step 2:
The number 448 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 448

Moving on to step 3:
When dividing 901 by 448, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 896 away from 901, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 448

On to step 4:
52 divided by 448 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 52, we end up with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 448

Advancing to step 5:
If we divide 521 by 448, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 201.0
If we subtract 448 from 521, we get 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 448

Moving on to step 6:
If we divide 735 by 448, we get 1 and a remainder of 287.
Write down 1 as next digit of the result. 
Result so far: 2011.0
Deduct 448 from 735 and we're left with 287.
Include the next digit (7) from the dividend after 287, then repeat: 2877 / 448

Going ahead to step 7:
448 can be fit into 2877 6 times, resulting in a remainder of 189.
The number 6 becomes the next digit in our result. 
Result so far: 20116.0
Subtract 2688 from 2877 to get 189.
Append the next digit (7) from the dividend to 189 and continue with: 1897 / 448

Step 8:
1897 divided by 448 is 4 with a remainder of 105.
The number 4 becomes the next digit in our result. 
Result so far: 201164.0
Subtract 1792 from 1897 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 9:
1050 divided by 448 is 2 with a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 201164.2
If we subtract 896 from 1050, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 10:
When dividing 1540 by 448, we get 3 with a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 201164.23
If we subtract 1344 from 1540, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
When dividing 1960 by 448, we get 4 with a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 201164.234
Subtracting 1792 from 1960 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 12:
The number 448 fits into 1680 3 times, leaving a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 201164.2343
The remainder is 336 after subtracting 1344 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 13:
The number 448 fits into 3360 7 times, leaving a remainder of 224.
Use 7 as the next digit of our solution. 
Result so far: 201164.23437
The remainder is 224 after subtracting 3136 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
If we divide 2240 by 448, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 201164.234375
If we take 2240 away from 2240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
The number 448 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 201164.234375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
448 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 201164.234375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 201164.234375, and the remainder is 0.0.
