We look at the division of 15516947 by 225 
Our goal is to divide 15516947 by 225.

On to step 1:
225 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 225

Let's proceed to step 2:
225 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 225

Step 3:
225 can be fit into 155 0 times, resulting in a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 155, we get 155.
Fetch the next digit (1) from the dividend, attach it to 155 and continue: 1551 / 225

Going ahead to step 4:
225 goes into 1551 6 times with a remainder of 201.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 1350 from 1551 to get 201.
Take the next digit (6) from the dividend and append it to 201, then repeat: 2016 / 225

Advancing to step 5:
If we divide 2016 by 225, we get 8 and a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we take 1800 away from 2016, we end up with 216.
Bring next digit (9) of the dividend behind the 216 and repeat the process: 2169 / 225

Let's proceed to step 6:
225 goes into 2169 9 times with a remainder of 144.
Use 9 as the next digit of our solution. 
Result so far: 689.0
The remainder is 144 after subtracting 2025 from 2169.
Grab the next digit (4) from the dividend, add it to 144, then carry on: 1444 / 225

Let's proceed to step 7:
1444 divided by 225 is 6 with a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 6896.0
The remainder is 94 after subtracting 1350 from 1444.
Append the next digit (7) from the dividend to 94 and continue with: 947 / 225

On to step 8:
The number 225 fits into 947 4 times, leaving a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 68964.0
If we subtract 900 from 947, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
If we divide 470 by 225, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 68964.2
Deduct 450 from 470 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 225 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 68964.2
Subtracting 0 from 200 leaves us 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.

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: 68964.208
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
225 can be fit into 2000 8 times, resulting in a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 68964.2088
If we subtract 1800 from 2000, 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.

After the division, we end up with 68964.2088 and a remainder of 0.002.
