685648 divided by 27 
The aim is to understand the frequency of 27 in 685648.

Going ahead to step 1:
When dividing 6 by 27, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 27

Step 2:
When dividing 68 by 27, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 54 away from 68, we end up with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 27

Advancing to step 3:
27 can be fit into 145 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 135 from 145 leaves us with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 27

Step 4:
The number 27 fits into 106 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 253.0
If we subtract 81 from 106, we get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 27

Going ahead to step 5:
254 divided by 27 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 2539.0
If we subtract 243 from 254, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 27

On to step 6:
When dividing 118 by 27, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 25394.0
Subtract 108 from 118 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 27, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 25394.3
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
27 goes into 190 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 25394.37
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 27 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 25394.37
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 27 fits into 100 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 25394.3703
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
If we divide 190 by 27, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 25394.37037
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
When dividing 10 by 27, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 25394.37037
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
27 can be fit into 100 3 times, resulting in a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 25394.3703703
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
When dividing 190 by 27, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 25394.37037037
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 25394.37037037, and the remainder is 1e-09.
