Let's divide 13645326 by 819
The aim is to understand the frequency of 819 in 13645326.

On to step 1:
When dividing 1 by 819, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 819

Step 2:
When dividing 13 by 819, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 819

Step 3:
136 divided by 819 is 0 with a remainder of 136.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 136, we end up with 136.
Include the next digit (4) from the dividend after 136, then repeat: 1364 / 819

On to step 4:
819 goes into 1364 1 times with a remainder of 545.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 819 from 1364 to get 545.
Fetch the next digit (5) from the dividend, attach it to 545 and continue: 5455 / 819

Let's proceed to step 5:
819 goes into 5455 6 times with a remainder of 541.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 4914 from 5455 and we're left with 541.
Grab the next digit (3) from the dividend, add it to 541, then carry on: 5413 / 819

Let's proceed to step 6:
5413 divided by 819 is 6 with a remainder of 499.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
Subtracting 4914 from 5413 leaves us with 499.
Grab the next digit (2) from the dividend, add it to 499, then carry on: 4992 / 819

Step 7:
When dividing 4992 by 819, we get 6 with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 1666.0
Subtracting 4914 from 4992 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 819

Step 8:
786 divided by 819 is 0 with a remainder of 786.
Write down 0 as next digit of the result. 
Result so far: 16660.0
Subtract 0 from 786 to get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

On to step 9:
When dividing 7860 by 819, we get 9 with a remainder of 489.
Write down 9 as next digit of the result. 
Result so far: 16660.9
If we take 7371 away from 7860, we end up with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 10:
819 goes into 4890 5 times with a remainder of 795.
Record the quotient 5 as the next digit in the result. 
Result so far: 16660.95
Subtract 4095 from 4890 to get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Step 11:
819 goes into 7950 9 times with a remainder of 579.
The number 9 becomes the next digit in our result. 
Result so far: 16660.959
Subtract 7371 from 7950 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Going ahead to step 12:
819 goes into 5790 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 16660.9597
The remainder is 57 after subtracting 5733 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
819 goes into 570 0 times with a remainder of 570.
Use 0 as the next digit of our solution. 
Result so far: 16660.9597
Subtracting 0 from 570 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 14:
The number 819 fits into 5700 6 times, leaving a remainder of 786.
Write down 6 as next digit of the result. 
Result so far: 16660.959706
If we subtract 4914 from 5700, we get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Moving on to step 15:
If we divide 7860 by 819, we get 9 and a remainder of 489.
Write down 9 as next digit of the result. 
Result so far: 16660.9597069
If we subtract 7371 from 7860, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 16:
If we divide 4890 by 819, we get 5 and a remainder of 795.
Write down 5 as next digit of the result. 
Result so far: 16660.95970695
If we take 4095 away from 4890, we end up with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

The quotient of the division is 16660.95970695, and the remainder is 7.95e-07.
