We're dividing 438666 by 34 
We want to divide 438666 by 34.

Moving on to step 1:
34 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 34

On to step 2:
When dividing 43 by 34, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 34 from 43 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 34

Going ahead to step 3:
The number 34 fits into 98 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 68 away from 98, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 34

Going ahead to step 4:
If we divide 306 by 34, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 129.0
Subtract 306 from 306 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 34

Advancing to step 5:
When dividing 6 by 34, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 1290.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 34

Step 6:
66 divided by 34 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 12901.0
Deduct 34 from 66 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
34 goes into 320 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 12901.9
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 34 fits into 140 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 12901.94
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
40 divided by 34 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 12901.941
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
If we divide 60 by 34, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 12901.9411
If we take 34 away from 60, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 12901.9411 with a remaining 0.00026.
