We're dividing 53889908 by 225 
We want to figure out the number of times 53889908 can be divided by 225.

On to step 1:
The number 225 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 225

On to step 2:
53 divided by 225 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 225

Let's proceed to step 3:
The number 225 fits into 538 2 times, leaving a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 450 from 538, we get 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 225

Advancing to step 4:
When dividing 888 by 225, we get 3 with a remainder of 213.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 675 away from 888, we end up with 213.
Take the next digit (9) from the dividend and append it to 213, then repeat: 2139 / 225

On to step 5:
225 goes into 2139 9 times with a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 239.0
If we take 2025 away from 2139, we end up with 114.
Take the next digit (9) from the dividend and append it to 114, then repeat: 1149 / 225

On to step 6:
1149 divided by 225 is 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 2395.0
Subtracting 1125 from 1149 leaves us with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 225

Moving on to step 7:
The number 225 fits into 240 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 23951.0
If we take 225 away from 240, we end up with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 225

Advancing to step 8:
225 goes into 158 0 times with a remainder of 158.
Put 0 as the next digit of the answer. 
Result so far: 239510.0
Subtracting 0 from 158 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 9:
When dividing 1580 by 225, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 239510.7
The remainder is 5 after subtracting 1575 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
225 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 239510.7
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
The number 225 fits into 500 2 times, leaving a remainder of 50.
The next digit of our result is 2. 
Result so far: 239510.702
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
225 goes into 500 2 times with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 239510.7022
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 239510.7022 with a remainder of 0.0005.
