We're dividing 7966587 by 225 
Let's see how many times 225 fits into 7966587.

On to step 1:
225 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 225

On to step 2:
When dividing 79 by 225, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Take the next digit (6) from the dividend and append it to 79, then repeat: 796 / 225

Advancing to step 3:
The number 225 fits into 796 3 times, leaving a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 675 from 796 leaves us with 121.
Fetch the next digit (6) from the dividend, attach it to 121 and continue: 1216 / 225

On to step 4:
The number 225 fits into 1216 5 times, leaving a remainder of 91.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 91 after subtracting 1125 from 1216.
Fetch the next digit (5) from the dividend, attach it to 91 and continue: 915 / 225

Advancing to step 5:
If we divide 915 by 225, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
If we subtract 900 from 915, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 225

Going ahead to step 6:
If we divide 158 by 225, we get 0 and a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 3540.0
If we subtract 0 from 158, we get 158.
Append the next digit (7) from the dividend to 158 and continue with: 1587 / 225

Moving on to step 7:
When dividing 1587 by 225, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 35407.0
If we subtract 1575 from 1587, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 225 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 35407.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 9:
225 can be fit into 1200 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 35407.05
Deduct 1125 from 1200 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
750 divided by 225 is 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 35407.053
The remainder is 75 after subtracting 675 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
225 goes into 750 3 times with a remainder of 75.
The next digit of our result is 3. 
Result so far: 35407.0533
If we subtract 675 from 750, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 35407.0533 with a remaining 0.00075.
