We look at the division of 51853106 by 225 
Our goal is to divide 51853106 by 225.

Going ahead to step 1:
225 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 225

Going ahead 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
If we take 0 away from 51, we end up with 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 225

Advancing to step 3:
225 can be fit into 518 2 times, resulting in a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 450 from 518, we get 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 225

Let's proceed to step 4:
225 goes into 685 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 675 from 685 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 225

Step 5:
225 goes into 103 0 times with a remainder of 103.
The next digit of our result is 0. 
Result so far: 230.0
Deduct 0 from 103 and we're left with 103.
Fetch the next digit (1) from the dividend, attach it to 103 and continue: 1031 / 225

Advancing to step 6:
When dividing 1031 by 225, we get 4 with a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 2304.0
If we take 900 away from 1031, we end up with 131.
Fetch the next digit (0) from the dividend, attach it to 131 and continue: 1310 / 225

Advancing to step 7:
225 can be fit into 1310 5 times, resulting in a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 23045.0
Subtract 1125 from 1310 to get 185.
Fetch the next digit (6) from the dividend, attach it to 185 and continue: 1856 / 225

Step 8:
The number 225 fits into 1856 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 230458.0
If we subtract 1800 from 1856, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 225 is 2 with a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 230458.2
If we subtract 450 from 560, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
If we divide 1100 by 225, we get 4 and a remainder of 200.
Record the quotient 4 as the next digit in the result. 
Result so far: 230458.24
If we subtract 900 from 1100, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
The number 225 fits into 2000 8 times, leaving a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 230458.248
Deduct 1800 from 2000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
225 can be fit into 2000 8 times, resulting in a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 230458.2488
Subtract 1800 from 2000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 230458.2488, and the remainder is 0.002.
