Let's divide 25105972 by 253
Our goal is to divide 25105972 by 253.

On to step 1:
When dividing 2 by 253, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 253

Going ahead to step 2:
When dividing 25 by 253, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 253

Moving on to step 3:
251 divided by 253 is 0 with a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 251 and we're left with 251.
Include the next digit (0) from the dividend after 251, then repeat: 2510 / 253

Let's proceed to step 4:
253 can be fit into 2510 9 times, resulting in a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 2277 from 2510 to get 233.
Take the next digit (5) from the dividend and append it to 233, then repeat: 2335 / 253

Step 5:
If we divide 2335 by 253, we get 9 and a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 2277 from 2335, we get 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 253

Step 6:
253 goes into 589 2 times with a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 992.0
Deduct 506 from 589 and we're left with 83.
Fetch the next digit (7) from the dividend, attach it to 83 and continue: 837 / 253

Step 7:
253 goes into 837 3 times with a remainder of 78.
The next digit of our result is 3. 
Result so far: 9923.0
If we take 759 away from 837, we end up with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 253

Advancing to step 8:
253 goes into 782 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 99233.0
If we take 759 away from 782, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
If we divide 230 by 253, we get 0 and a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 99233.0
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
253 goes into 2300 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 99233.09
If we take 2277 away from 2300, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
253 goes into 230 0 times with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 99233.09
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 12:
If we divide 2300 by 253, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 99233.0909
Subtracting 2277 from 2300 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
253 can be fit into 230 0 times, resulting in a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 99233.0909
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 14:
If we divide 2300 by 253, we get 9 and a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 99233.090909
The remainder is 23 after subtracting 2277 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 15:
If we divide 230 by 253, we get 0 and a remainder of 230.
The next digit of our result is 0. 
Result so far: 99233.090909
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 16:
253 can be fit into 2300 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 99233.09090909
If we take 2277 away from 2300, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 99233.09090909 with a remainder of 2.3e-08.
