729126 ÷ 514 
The aim is to understand the frequency of 514 in 729126.

On to step 1:
514 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 514

Going ahead to step 2:
When dividing 72 by 514, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 514

Step 3:
729 divided by 514 is 1 with a remainder of 215.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 215 after subtracting 514 from 729.
Include the next digit (1) from the dividend after 215, then repeat: 2151 / 514

On to step 4:
If we divide 2151 by 514, we get 4 and a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 95 after subtracting 2056 from 2151.
Include the next digit (2) from the dividend after 95, then repeat: 952 / 514

Step 5:
When dividing 952 by 514, we get 1 with a remainder of 438.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 438 after subtracting 514 from 952.
Take the next digit (6) from the dividend and append it to 438, then repeat: 4386 / 514

Going ahead to step 6:
The number 514 fits into 4386 8 times, leaving a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 1418.0
Subtracting 4112 from 4386 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 7:
514 can be fit into 2740 5 times, resulting in a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 1418.5
If we subtract 2570 from 2740, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 8:
If we divide 1700 by 514, we get 3 and a remainder of 158.
Use 3 as the next digit of our solution. 
Result so far: 1418.53
If we subtract 1542 from 1700, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
514 goes into 1580 3 times with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 1418.533
If we subtract 1542 from 1580, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 1418.533, and the remainder is 0.0038.
