308394 ÷ 79 
Our goal is to divide 308394 by 79.

Going ahead to step 1:
79 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 79

Step 2:
30 divided by 79 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 79

Advancing to step 3:
308 divided by 79 is 3 with a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 237 away from 308, we end up with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 79

Moving on to step 4:
If we divide 713 by 79, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtracting 711 from 713 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 79

Step 5:
If we divide 29 by 79, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 390.0
Subtracting 0 from 29 leaves us with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 79

Advancing to step 6:
When dividing 294 by 79, we get 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 3903.0
Subtract 237 from 294 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
When dividing 570 by 79, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 3903.7
The remainder is 17 after subtracting 553 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
79 can be fit into 170 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3903.72
Subtracting 158 from 170 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
79 can be fit into 120 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 3903.721
If we take 79 away from 120, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
When dividing 410 by 79, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3903.7215
The remainder is 15 after subtracting 395 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
The number 79 fits into 150 1 times, leaving a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 3903.72151
Deduct 79 from 150 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 12:
When dividing 710 by 79, we get 8 with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 3903.721518
Subtracting 632 from 710 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
The number 79 fits into 780 9 times, leaving a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 3903.7215189
Subtracting 711 from 780 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
79 can be fit into 690 8 times, resulting in a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 3903.72151898
Subtract 632 from 690 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 3903.72151898, with a leftover of 5.8e-08.
