13505728 ÷ 843 
The aim is to understand the frequency of 843 in 13505728.

Let's proceed to step 1:
843 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 843

Step 2:
If we divide 13 by 843, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 843

Going ahead to step 3:
When dividing 135 by 843, we get 0 with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 135 leaves us with 135.
Bring next digit (0) of the dividend behind the 135 and repeat the process: 1350 / 843

On to step 4:
If we divide 1350 by 843, we get 1 and a remainder of 507.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 843 from 1350 and we're left with 507.
Append the next digit (5) from the dividend to 507 and continue with: 5075 / 843

On to step 5:
843 goes into 5075 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 17 after subtracting 5058 from 5075.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 843

Going ahead to step 6:
If we divide 177 by 843, we get 0 and a remainder of 177.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we take 0 away from 177, we end up with 177.
Include the next digit (2) from the dividend after 177, then repeat: 1772 / 843

Step 7:
If we divide 1772 by 843, we get 2 and a remainder of 86.
The next digit of our result is 2. 
Result so far: 1602.0
Subtract 1686 from 1772 to get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 843

Advancing to step 8:
868 divided by 843 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 16021.0
Subtracting 843 from 868 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
If we divide 250 by 843, we get 0 and a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 16021.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
When dividing 2500 by 843, we get 2 with a remainder of 814.
The number 2 becomes the next digit in our result. 
Result so far: 16021.02
If we take 1686 away from 2500, we end up with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Going ahead to step 11:
843 goes into 8140 9 times with a remainder of 553.
The number 9 becomes the next digit in our result. 
Result so far: 16021.029
Deduct 7587 from 8140 and we're left with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Going ahead to step 12:
5530 divided by 843 is 6 with a remainder of 472.
Put 6 as the next digit of the answer. 
Result so far: 16021.0296
The remainder is 472 after subtracting 5058 from 5530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 13:
The number 843 fits into 4720 5 times, leaving a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 16021.02965
The remainder is 505 after subtracting 4215 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 14:
843 goes into 5050 5 times with a remainder of 835.
Use 5 as the next digit of our solution. 
Result so far: 16021.029655
Subtract 4215 from 5050 to get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

The quotient of the division is 16021.029655, and the remainder is 8.35e-05.
