349564 divided by 27 
The aim is to understand the frequency of 27 in 349564.

Step 1:
The number 27 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 27

Going ahead to step 2:
If we divide 34 by 27, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 27 from 34 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 27

Moving on to step 3:
79 divided by 27 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 54 from 79 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 27

On to step 4:
When dividing 255 by 27, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 243 away from 255, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 27

On to step 5:
27 can be fit into 126 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1294.0
If we take 108 away from 126, we end up with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 27

Let's proceed to step 6:
When dividing 184 by 27, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 12946.0
The remainder is 22 after subtracting 162 from 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 27, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 12946.8
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
27 goes into 40 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 12946.81
Subtracting 27 from 40 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 27 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 12946.814
The remainder is 22 after subtracting 108 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
27 goes into 220 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 12946.8148
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
If we divide 40 by 27, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 12946.81481
If we take 27 away from 40, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
27 can be fit into 130 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 12946.814814
Subtracting 108 from 130 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
27 goes into 220 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 12946.8148148
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 27 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 12946.81481481
Deduct 27 from 40 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 12946.81481481 and a remainder of 1.3e-08.
