We look at the division of 73231225 by 253 
Our goal is to divide 73231225 by 253.

On to step 1:
The number 253 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 253

Going ahead to step 2:
When dividing 73 by 253, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Include the next digit (2) from the dividend after 73, then repeat: 732 / 253

Moving on to step 3:
253 goes into 732 2 times with a remainder of 226.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 506 from 732 leaves us with 226.
Grab the next digit (3) from the dividend, add it to 226, then carry on: 2263 / 253

Advancing to step 4:
2263 divided by 253 is 8 with a remainder of 239.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 239 after subtracting 2024 from 2263.
Append the next digit (1) from the dividend to 239 and continue with: 2391 / 253

Let's proceed to step 5:
If we divide 2391 by 253, we get 9 and a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Deduct 2277 from 2391 and we're left with 114.
Bring next digit (2) of the dividend behind the 114 and repeat the process: 1142 / 253

Step 6:
The number 253 fits into 1142 4 times, leaving a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 2894.0
If we subtract 1012 from 1142, we get 130.
Include the next digit (2) from the dividend after 130, then repeat: 1302 / 253

Advancing to step 7:
When dividing 1302 by 253, we get 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 28945.0
The remainder is 37 after subtracting 1265 from 1302.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 253

Going ahead to step 8:
253 can be fit into 375 1 times, resulting in a remainder of 122.
The next digit of our result is 1. 
Result so far: 289451.0
The remainder is 122 after subtracting 253 from 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 9:
When dividing 1220 by 253, we get 4 with a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 289451.4
If we take 1012 away from 1220, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 10:
When dividing 2080 by 253, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 289451.48
Deduct 2024 from 2080 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
253 can be fit into 560 2 times, resulting in a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 289451.482
Subtract 506 from 560 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
540 divided by 253 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 289451.4822
If we take 506 away from 540, 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.

After the division, we end up with 289451.4822 and a remainder of 0.00034.
