We look at the division of 213780 by 14 
The aim is to understand the frequency of 14 in 213780.

Advancing to step 1:
14 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 14

On to step 2:
14 goes into 21 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 14 from 21 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 14

Moving on to step 3:
14 can be fit into 73 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 70 from 73, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 14

Let's proceed to step 4:
The number 14 fits into 37 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we take 28 away from 37, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 14

On to step 5:
14 goes into 98 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 1527.0
Subtract 98 from 98 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 14

Moving on to step 6:
14 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15270.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 14 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15270.0
Deduct 0 from 0 and we're left 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.

Moving on to step 8:
The number 14 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15270.0
If we subtract 0 from 0, we get 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 quotient of the division is 15270.0, and the remainder is 0.0.
