Let's divide 242290 by 79
We want to divide 242290 by 79.

On to step 1:
When dividing 2 by 79, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 79

Advancing to step 2:
79 can be fit into 24 0 times, resulting in a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 79

Step 3:
If we divide 242 by 79, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 237 from 242 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 79

Moving on to step 4:
The number 79 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 52 to get 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 79

Advancing to step 5:
79 can be fit into 529 6 times, resulting in a remainder of 55.
The next digit of our result is 6. 
Result so far: 306.0
Deduct 474 from 529 and we're left with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 79

On to step 6:
When dividing 550 by 79, we get 6 with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 3066.0
Subtracting 474 from 550 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
79 can be fit into 760 9 times, resulting in a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 3066.9
Subtract 711 from 760 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
The number 79 fits into 490 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3066.96
If we subtract 474 from 490, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
79 can be fit into 160 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 3066.962
Deduct 158 from 160 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 79, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3066.962
Subtract 0 from 20 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.

On to step 11:
79 can be fit into 200 2 times, resulting in a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 3066.96202
If we take 158 away from 200, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3066.962025
Deduct 395 from 420 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 13:
79 goes into 250 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3066.9620253
The remainder is 13 after subtracting 237 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
If we divide 130 by 79, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 3066.96202531
Deduct 79 from 130 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 3066.96202531, with a leftover of 5.1e-08.
