843641 ÷ 27 
The aim is to understand the frequency of 27 in 843641.

Advancing to step 1:
27 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 27

Going ahead to step 2:
When dividing 84 by 27, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 81 from 84 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 27

Moving on to step 3:
27 goes into 33 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 27 away from 33, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 27

Going ahead to step 4:
66 divided by 27 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 312.0
If we subtract 54 from 66, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 27

On to step 5:
124 divided by 27 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 3124.0
Subtract 108 from 124 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 27

Step 6:
27 goes into 161 5 times with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 31245.0
If we subtract 135 from 161, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
When dividing 260 by 27, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 31245.9
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
If we divide 170 by 27, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 31245.96
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 27 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 31245.962
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
27 can be fit into 260 9 times, resulting in a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 31245.9629
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
27 can be fit into 170 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 31245.96296
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
27 goes into 80 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 31245.962962
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
27 goes into 260 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 31245.9629629
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
27 goes into 170 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 31245.96296296
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 31245.96296296 and a remainder of 8e-09.
