We look at the division of 1725340 by 814 
The aim is to understand the frequency of 814 in 1725340.

On to step 1:
If we divide 1 by 814, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 814

Step 2:
17 divided by 814 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 814

Moving on to step 3:
814 can be fit into 172 0 times, resulting in a remainder of 172.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 172, we get 172.
Grab the next digit (5) from the dividend, add it to 172, then carry on: 1725 / 814

Advancing to step 4:
814 can be fit into 1725 2 times, resulting in a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1628 from 1725, we get 97.
Take the next digit (3) from the dividend and append it to 97, then repeat: 973 / 814

On to step 5:
973 divided by 814 is 1 with a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 814 from 973 and we're left with 159.
Fetch the next digit (4) from the dividend, attach it to 159 and continue: 1594 / 814

Step 6:
If we divide 1594 by 814, we get 1 and a remainder of 780.
Write down 1 as next digit of the result. 
Result so far: 211.0
If we subtract 814 from 1594, we get 780.
Take the next digit (0) from the dividend and append it to 780, then repeat: 7800 / 814

Let's proceed to step 7:
If we divide 7800 by 814, we get 9 and a remainder of 474.
Record the quotient 9 as the next digit in the result. 
Result so far: 2119.0
If we take 7326 away from 7800, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 8:
When dividing 4740 by 814, we get 5 with a remainder of 670.
Write down 5 as next digit of the result. 
Result so far: 2119.5
Subtract 4070 from 4740 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 9:
814 can be fit into 6700 8 times, resulting in a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 2119.58
If we take 6512 away from 6700, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 10:
1880 divided by 814 is 2 with a remainder of 252.
Write down 2 as next digit of the result. 
Result so far: 2119.582
Subtracting 1628 from 1880 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
The number 814 fits into 2520 3 times, leaving a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 2119.5823
If we take 2442 away from 2520, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
814 goes into 780 0 times with a remainder of 780.
The next digit of our result is 0. 
Result so far: 2119.5823
Subtracting 0 from 780 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 13:
814 goes into 7800 9 times with a remainder of 474.
The next digit of our result is 9. 
Result so far: 2119.582309
Subtracting 7326 from 7800 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 14:
814 goes into 4740 5 times with a remainder of 670.
Put 5 as the next digit of the answer. 
Result so far: 2119.5823095
If we subtract 4070 from 4740, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 15:
814 goes into 6700 8 times with a remainder of 188.
Record the quotient 8 as the next digit in the result. 
Result so far: 2119.58230958
If we take 6512 away from 6700, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The quotient of the division is 2119.58230958, and the remainder is 1.88e-07.
