We look at the division of 17006455 by 843 
The aim is to understand the frequency of 843 in 17006455.

Let's proceed to step 1:
843 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 843

On to step 2:
When dividing 17 by 843, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 843

On to step 3:
843 can be fit into 170 0 times, resulting in a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 170, we end up with 170.
Grab the next digit (0) from the dividend, add it to 170, then carry on: 1700 / 843

On to step 4:
843 can be fit into 1700 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1686 from 1700 to get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 843

Let's proceed to step 5:
843 goes into 146 0 times with a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 146, we end up with 146.
Grab the next digit (4) from the dividend, add it to 146, then carry on: 1464 / 843

Going ahead to step 6:
The number 843 fits into 1464 1 times, leaving a remainder of 621.
Write down 1 as next digit of the result. 
Result so far: 201.0
The remainder is 621 after subtracting 843 from 1464.
Append the next digit (5) from the dividend to 621 and continue with: 6215 / 843

Advancing to step 7:
843 can be fit into 6215 7 times, resulting in a remainder of 314.
The number 7 becomes the next digit in our result. 
Result so far: 2017.0
If we subtract 5901 from 6215, we get 314.
Include the next digit (5) from the dividend after 314, then repeat: 3145 / 843

Let's proceed to step 8:
The number 843 fits into 3145 3 times, leaving a remainder of 616.
Put 3 as the next digit of the answer. 
Result so far: 20173.0
Deduct 2529 from 3145 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 9:
6160 divided by 843 is 7 with a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 20173.7
Deduct 5901 from 6160 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 10:
The number 843 fits into 2590 3 times, leaving a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 20173.73
Subtracting 2529 from 2590 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 11:
843 goes into 610 0 times with a remainder of 610.
Use 0 as the next digit of our solution. 
Result so far: 20173.73
Subtracting 0 from 610 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 12:
The number 843 fits into 6100 7 times, leaving a remainder of 199.
Write down 7 as next digit of the result. 
Result so far: 20173.7307
If we take 5901 away from 6100, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 13:
843 can be fit into 1990 2 times, resulting in a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 20173.73072
If we take 1686 away from 1990, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 14:
When dividing 3040 by 843, we get 3 with a remainder of 511.
Record the quotient 3 as the next digit in the result. 
Result so far: 20173.730723
Subtract 2529 from 3040 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 15:
If we divide 5110 by 843, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 20173.7307236
Subtracting 5058 from 5110 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 16:
If we divide 520 by 843, we get 0 and a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 20173.7307236
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 20173.7307236 with a remainder of 5.2e-07.
