421166 ÷ 14 
Let's see how many times 14 fits into 421166.

On to step 1:
When dividing 4 by 14, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 14

Advancing to step 2:
14 goes into 42 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 42 away from 42, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 14

Going ahead to step 3:
14 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 1 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 14

Step 4:
If we divide 11 by 14, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 300.0
Subtracting 0 from 11 leaves us with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 14

Step 5:
14 can be fit into 116 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 3008.0
If we take 112 away from 116, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 14

Going ahead to step 6:
When dividing 46 by 14, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 30083.0
If we subtract 42 from 46, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 30083.2
Subtract 28 from 40 to get 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 8:
If we divide 120 by 14, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 30083.28
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 14, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 30083.285
Deduct 70 from 80 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 14, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 30083.2857
Subtract 98 from 100 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
14 goes into 20 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 30083.28571
If we subtract 14 from 20, we get 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 12:
If we divide 60 by 14, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 30083.285714
If we take 56 away from 60, we end up 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.

On to step 13:
40 divided by 14 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 30083.2857142
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
120 divided by 14 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 30083.28571428
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 30083.28571428 with a remainder of 8e-09.
