We look at the division of 71543123 by 225 
We want to figure out the number of times 71543123 can be divided by 225.

Moving on to step 1:
If we divide 7 by 225, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 225

Step 2:
When dividing 71 by 225, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 225

Going ahead to step 3:
If we divide 715 by 225, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 40 after subtracting 675 from 715.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 225

Advancing to step 4:
If we divide 404 by 225, we get 1 and a remainder of 179.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 179 after subtracting 225 from 404.
Fetch the next digit (3) from the dividend, attach it to 179 and continue: 1793 / 225

Going ahead to step 5:
The number 225 fits into 1793 7 times, leaving a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 317.0
Subtracting 1575 from 1793 leaves us with 218.
Fetch the next digit (1) from the dividend, attach it to 218 and continue: 2181 / 225

Step 6:
If we divide 2181 by 225, we get 9 and a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 3179.0
The remainder is 156 after subtracting 2025 from 2181.
Include the next digit (2) from the dividend after 156, then repeat: 1562 / 225

Advancing to step 7:
When dividing 1562 by 225, we get 6 with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 31796.0
Subtracting 1350 from 1562 leaves us with 212.
Grab the next digit (3) from the dividend, add it to 212, then carry on: 2123 / 225

Let's proceed to step 8:
2123 divided by 225 is 9 with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 317969.0
If we take 2025 away from 2123, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
When dividing 980 by 225, we get 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 317969.4
If we subtract 900 from 980, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
225 goes into 800 3 times with a remainder of 125.
The next digit of our result is 3. 
Result so far: 317969.43
The remainder is 125 after subtracting 675 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 11:
1250 divided by 225 is 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 317969.435
Subtract 1125 from 1250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
225 goes into 1250 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 317969.4355
Subtracting 1125 from 1250 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The quotient of the division is 317969.4355, and the remainder is 0.00125.
