We're dividing 51148766 by 223 
We're looking to find how many times 223 goes into 51148766.

On to step 1:
When dividing 5 by 223, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 223

Going ahead to step 2:
223 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 223

On to step 3:
223 can be fit into 511 2 times, resulting in a remainder of 65.
The next digit of our result is 2. 
Result so far: 2.0
If we take 446 away from 511, we end up with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 223

On to step 4:
223 goes into 654 2 times with a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 446 from 654 to get 208.
Grab the next digit (8) from the dividend, add it to 208, then carry on: 2088 / 223

On to step 5:
When dividing 2088 by 223, we get 9 with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
The remainder is 81 after subtracting 2007 from 2088.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 223

Advancing to step 6:
223 can be fit into 817 3 times, resulting in a remainder of 148.
The next digit of our result is 3. 
Result so far: 2293.0
Subtract 669 from 817 to get 148.
Include the next digit (6) from the dividend after 148, then repeat: 1486 / 223

On to step 7:
When dividing 1486 by 223, we get 6 with a remainder of 148.
Use 6 as the next digit of our solution. 
Result so far: 22936.0
Subtract 1338 from 1486 to get 148.
Include the next digit (6) from the dividend after 148, then repeat: 1486 / 223

On to step 8:
223 can be fit into 1486 6 times, resulting in a remainder of 148.
The next digit of our result is 6. 
Result so far: 229366.0
If we subtract 1338 from 1486, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
When dividing 1480 by 223, we get 6 with a remainder of 142.
The next digit of our result is 6. 
Result so far: 229366.6
If we take 1338 away from 1480, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 10:
When dividing 1420 by 223, we get 6 with a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 229366.66
If we take 1338 away from 1420, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final result is 229366.66 with a remainder of 0.082.
