51298830 ÷ 225 
We want to figure out the number of times 51298830 can be divided by 225.

Advancing to step 1:
The number 225 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 225

Moving on to step 2:
225 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
Subtract 0 from 51 to get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 225

Advancing to step 3:
When dividing 512 by 225, we get 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 450 from 512 to get 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 225

Advancing to step 4:
225 goes into 629 2 times with a remainder of 179.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 450 from 629, we get 179.
Bring next digit (8) of the dividend behind the 179 and repeat the process: 1798 / 225

Advancing to step 5:
If we divide 1798 by 225, we get 7 and a remainder of 223.
Put 7 as the next digit of the answer. 
Result so far: 227.0
The remainder is 223 after subtracting 1575 from 1798.
Fetch the next digit (8) from the dividend, attach it to 223 and continue: 2238 / 225

On to step 6:
The number 225 fits into 2238 9 times, leaving a remainder of 213.
The next digit of our result is 9. 
Result so far: 2279.0
Subtract 2025 from 2238 to get 213.
Take the next digit (3) from the dividend and append it to 213, then repeat: 2133 / 225

Moving on to step 7:
2133 divided by 225 is 9 with a remainder of 108.
Use 9 as the next digit of our solution. 
Result so far: 22799.0
The remainder is 108 after subtracting 2025 from 2133.
Fetch the next digit (0) from the dividend, attach it to 108 and continue: 1080 / 225

Step 8:
1080 divided by 225 is 4 with a remainder of 180.
The next digit of our result is 4. 
Result so far: 227994.0
If we subtract 900 from 1080, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 9:
225 can be fit into 1800 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 227994.8
If we subtract 1800 from 1800, we get 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 10:
225 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 227994.8
Deduct 0 from 0 and we're left 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.

Advancing to step 11:
The number 225 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 227994.8
If we subtract 0 from 0, we get 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 227994.8, and the remainder is 0.0.
