We're dividing 51494685 by 448 
Let's see how many times 448 fits into 51494685.

Moving on to step 1:
448 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 448

Moving on to step 2:
448 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 448

Moving on to step 3:
448 goes into 514 1 times with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 448 from 514, we get 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 448

Advancing to step 4:
If we divide 669 by 448, we get 1 and a remainder of 221.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 221 after subtracting 448 from 669.
Take the next digit (4) from the dividend and append it to 221, then repeat: 2214 / 448

On to step 5:
448 goes into 2214 4 times with a remainder of 422.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we subtract 1792 from 2214, we get 422.
Grab the next digit (6) from the dividend, add it to 422, then carry on: 4226 / 448

Going ahead to step 6:
4226 divided by 448 is 9 with a remainder of 194.
Put 9 as the next digit of the answer. 
Result so far: 1149.0
Subtract 4032 from 4226 to get 194.
Fetch the next digit (8) from the dividend, attach it to 194 and continue: 1948 / 448

Step 7:
The number 448 fits into 1948 4 times, leaving a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 11494.0
The remainder is 156 after subtracting 1792 from 1948.
Bring next digit (5) of the dividend behind the 156 and repeat the process: 1565 / 448

Step 8:
The number 448 fits into 1565 3 times, leaving a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 114943.0
Deduct 1344 from 1565 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 9:
2210 divided by 448 is 4 with a remainder of 418.
Put 4 as the next digit of the answer. 
Result so far: 114943.4
Subtract 1792 from 2210 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 10:
448 can be fit into 4180 9 times, resulting in a remainder of 148.
Use 9 as the next digit of our solution. 
Result so far: 114943.49
Subtracting 4032 from 4180 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 11:
The number 448 fits into 1480 3 times, leaving a remainder of 136.
The next digit of our result is 3. 
Result so far: 114943.493
Deduct 1344 from 1480 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 12:
The number 448 fits into 1360 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 114943.4933
Subtract 1344 from 1360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 114943.4933, with a leftover of 0.00016.
