521940 ÷ 14 
We want to figure out the number of times 521940 can be divided by 14.

Step 1:
14 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 14

Going ahead to step 2:
14 can be fit into 52 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 42 away from 52, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 14

Advancing to step 3:
101 divided by 14 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 98 from 101 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 14

Going ahead to step 4:
39 divided by 14 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 372.0
Subtracting 28 from 39 leaves us with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 14

Step 5:
14 can be fit into 114 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 3728.0
Subtract 112 from 114 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 14

Advancing to step 6:
If we divide 20 by 14, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 37281.0
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.

Step 7:
If we divide 60 by 14, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 37281.4
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.

On to step 8:
40 divided by 14 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 37281.42
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.

Advancing to step 9:
If we divide 120 by 14, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 37281.428
Deduct 112 from 120 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.

On to step 10:
14 can be fit into 80 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 37281.4285
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.

Going ahead to step 11:
100 divided by 14 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 37281.42857
Subtracting 98 from 100 leaves us with 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 12:
The number 14 fits into 20 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 37281.428571
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
If we divide 60 by 14, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 37281.4285714
Subtract 56 from 60 to 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.

Step 14:
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: 37281.42857142
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.

Our division results in 37281.42857142 with a remaining 1.2e-08.
