421937 ÷ 14 
We want to divide 421937 by 14.

Let's proceed to step 1:
14 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
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 14

On to step 2:
42 divided by 14 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 42 from 42 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 14

Step 3:
14 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 14

Step 4:
The number 14 fits into 19 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 301.0
The remainder is 5 after subtracting 14 from 19.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 14

On to step 5:
If we divide 53 by 14, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3013.0
Subtract 42 from 53 to get 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 14

On to step 6:
If we divide 117 by 14, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 30138.0
If we take 112 away from 117, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
When dividing 50 by 14, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 30138.3
Deduct 42 from 50 and we're left 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.

Moving on to step 8:
14 goes into 80 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 30138.35
If we subtract 70 from 80, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 14, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 30138.357
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.

Moving on to step 10:
When dividing 20 by 14, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 30138.3571
If we take 14 away from 20, we end up 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.

Advancing to step 11:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 30138.35714
Deduct 56 from 60 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.

Advancing to step 12:
14 can be fit into 40 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 30138.357142
Deduct 28 from 40 and we're left 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.

Going ahead to step 13:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 30138.3571428
Subtracting 112 from 120 leaves us 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.

Advancing to step 14:
The number 14 fits into 80 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 30138.35714285
Subtract 70 from 80 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 30138.35714285 and a remainder of 1e-08.
