We divide 253992 by 79
Let's see how many times 79 fits into 253992.

On to step 1:
79 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 79

Moving on to step 2:
79 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 79

Advancing to step 3:
When dividing 253 by 79, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 237 from 253 to get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 79

Step 4:
The number 79 fits into 169 2 times, leaving a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 158 away from 169, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 79

Advancing to step 5:
119 divided by 79 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 321.0
Subtracting 79 from 119 leaves us with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 79

Step 6:
402 divided by 79 is 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 3215.0
The remainder is 7 after subtracting 395 from 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
79 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 3215.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
If we divide 700 by 79, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 3215.08
Subtract 632 from 700 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
680 divided by 79 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 3215.088
If we subtract 632 from 680, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 3215.088 with a remainder of 0.0048.
