We look at the division of 253145 by 80 
We're looking to find how many times 80 goes into 253145.

Moving on to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 80

Moving on to step 2:
The number 80 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 80

On to step 3:
The number 80 fits into 253 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 240 from 253 and we're left with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 80

Step 4:
The number 80 fits into 131 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 80 from 131 to get 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 80

Advancing to step 5:
When dividing 514 by 80, we get 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
If we subtract 480 from 514, we get 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 80

On to step 6:
80 goes into 345 4 times with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 3164.0
Deduct 320 from 345 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.

Moving on to step 7:
The number 80 fits into 250 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3164.3
Deduct 240 from 250 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 80 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 3164.31
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 3164.312
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 3164.3125
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3164.3125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3164.3125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3164.3125 and a remainder of 0.0.
