We're dividing 309408 by 22 
We want to divide 309408 by 22.

Let's proceed to step 1:
3 divided by 22 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 22

Moving on to step 2:
30 divided by 22 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 8 after subtracting 22 from 30.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 22

On to step 3:
The number 22 fits into 89 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 88 from 89 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 22

Going ahead to step 4:
When dividing 14 by 22, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 22

Let's proceed to step 5:
The number 22 fits into 140 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1406.0
Deduct 132 from 140 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 22

Step 6:
22 can be fit into 88 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14064.0
Subtracting 88 from 88 leaves us 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.

Advancing to step 7:
0 divided by 22 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14064.0
If we take 0 away from 0, 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.

Going ahead to step 8:
If we divide 0 by 22, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14064.0
Subtracting 0 from 0 leaves us 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.

The final outcome is 14064.0, with a leftover of 0.0.
