We look at the division of 40415884 by 225 
We want to divide 40415884 by 225.

Advancing to step 1:
225 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 225

Let's proceed to step 2:
When dividing 40 by 225, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 225

Let's proceed to step 3:
When dividing 404 by 225, we get 1 with a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 225 from 404 to get 179.
Bring next digit (1) of the dividend behind the 179 and repeat the process: 1791 / 225

Going ahead to step 4:
If we divide 1791 by 225, we get 7 and a remainder of 216.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 1575 from 1791, we get 216.
Grab the next digit (5) from the dividend, add it to 216, then carry on: 2165 / 225

Moving on to step 5:
2165 divided by 225 is 9 with a remainder of 140.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Deduct 2025 from 2165 and we're left with 140.
Take the next digit (8) from the dividend and append it to 140, then repeat: 1408 / 225

On to step 6:
1408 divided by 225 is 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 1796.0
Deduct 1350 from 1408 and we're left with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 225

On to step 7:
The number 225 fits into 588 2 times, leaving a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 17962.0
If we take 450 away from 588, we end up with 138.
Bring next digit (4) of the dividend behind the 138 and repeat the process: 1384 / 225

Let's proceed to step 8:
1384 divided by 225 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 179626.0
If we take 1350 away from 1384, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 225, we get 1 and a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 179626.1
If we subtract 225 from 340, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 10:
225 can be fit into 1150 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 179626.15
Deduct 1125 from 1150 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
225 goes into 250 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 179626.151
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
225 can be fit into 250 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 179626.1511
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 179626.1511 and a remainder of 0.00025.
