Let's divide 51204184 by 245
We want to figure out the number of times 51204184 can be divided by 245.

Step 1:
245 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 245

Let's proceed to step 2:
245 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 245

Advancing to step 3:
512 divided by 245 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 490 from 512, we get 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 245

Step 4:
220 divided by 245 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 220 leaves us with 220.
Grab the next digit (4) from the dividend, add it to 220, then carry on: 2204 / 245

Advancing to step 5:
245 can be fit into 2204 8 times, resulting in a remainder of 244.
Put 8 as the next digit of the answer. 
Result so far: 208.0
Subtracting 1960 from 2204 leaves us with 244.
Include the next digit (1) from the dividend after 244, then repeat: 2441 / 245

Let's proceed to step 6:
The number 245 fits into 2441 9 times, leaving a remainder of 236.
Write down 9 as next digit of the result. 
Result so far: 2089.0
If we subtract 2205 from 2441, we get 236.
Fetch the next digit (8) from the dividend, attach it to 236 and continue: 2368 / 245

Advancing to step 7:
245 goes into 2368 9 times with a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 20899.0
The remainder is 163 after subtracting 2205 from 2368.
Append the next digit (4) from the dividend to 163 and continue with: 1634 / 245

On to step 8:
If we divide 1634 by 245, we get 6 and a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 208996.0
The remainder is 164 after subtracting 1470 from 1634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 9:
245 goes into 1640 6 times with a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 208996.6
Subtracting 1470 from 1640 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
245 can be fit into 1700 6 times, resulting in a remainder of 230.
Write down 6 as next digit of the result. 
Result so far: 208996.66
Deduct 1470 from 1700 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 208996.66 and a remainder of 0.23.
