63684259 ÷ 843 
The aim is to understand the frequency of 843 in 63684259.

On to step 1:
843 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 843

Advancing to step 2:
The number 843 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 843

Let's proceed to step 3:
When dividing 636 by 843, we get 0 with a remainder of 636.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 636 leaves us with 636.
Take the next digit (8) from the dividend and append it to 636, then repeat: 6368 / 843

On to step 4:
The number 843 fits into 6368 7 times, leaving a remainder of 467.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 5901 from 6368 leaves us with 467.
Fetch the next digit (4) from the dividend, attach it to 467 and continue: 4674 / 843

Going ahead to step 5:
When dividing 4674 by 843, we get 5 with a remainder of 459.
The next digit of our result is 5. 
Result so far: 75.0
If we take 4215 away from 4674, we end up with 459.
Bring next digit (2) of the dividend behind the 459 and repeat the process: 4592 / 843

Going ahead to step 6:
843 can be fit into 4592 5 times, resulting in a remainder of 377.
The number 5 becomes the next digit in our result. 
Result so far: 755.0
If we take 4215 away from 4592, we end up with 377.
Bring next digit (5) of the dividend behind the 377 and repeat the process: 3775 / 843

Advancing to step 7:
843 can be fit into 3775 4 times, resulting in a remainder of 403.
The number 4 becomes the next digit in our result. 
Result so far: 7554.0
If we subtract 3372 from 3775, we get 403.
Fetch the next digit (9) from the dividend, attach it to 403 and continue: 4039 / 843

Step 8:
The number 843 fits into 4039 4 times, leaving a remainder of 667.
Use 4 as the next digit of our solution. 
Result so far: 75544.0
The remainder is 667 after subtracting 3372 from 4039.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Going ahead to step 9:
If we divide 6670 by 843, we get 7 and a remainder of 769.
Put 7 as the next digit of the answer. 
Result so far: 75544.7
If we subtract 5901 from 6670, we get 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Let's proceed to step 10:
When dividing 7690 by 843, we get 9 with a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 75544.79
Subtracting 7587 from 7690 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 11:
843 can be fit into 1030 1 times, resulting in a remainder of 187.
Record the quotient 1 as the next digit in the result. 
Result so far: 75544.791
Deduct 843 from 1030 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 12:
843 goes into 1870 2 times with a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 75544.7912
Subtract 1686 from 1870 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 13:
843 can be fit into 1840 2 times, resulting in a remainder of 154.
Record the quotient 2 as the next digit in the result. 
Result so far: 75544.79122
If we take 1686 away from 1840, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final outcome is 75544.79122, with a leftover of 0.000154.
