The aim is to understand the frequency of 27 in 87805643.

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
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 27

Moving on to step 2:
The number 27 fits into 87 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 6 after subtracting 81 from 87.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 27

Moving on to step 3:
68 divided by 27 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 32.0
The remainder is 14 after subtracting 54 from 68.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 27

Advancing to step 4:
27 goes into 140 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 325.0
Deduct 135 from 140 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 27

Going ahead to step 5:
If we divide 55 by 27, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 3252.0
If we subtract 54 from 55, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 27

Advancing to step 6:
16 divided by 27 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 32520.0
Subtract 0 from 16 to get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 27

On to step 7:
27 can be fit into 164 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 325206.0
If we take 162 away from 164, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 27

Step 8:
23 divided by 27 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 3252060.0
If we take 0 away from 23, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
If we divide 230 by 27, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 3252060.8
The remainder is 14 after subtracting 216 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
140 divided by 27 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3252060.85
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
If we divide 50 by 27, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 3252060.851
Deduct 27 from 50 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
230 divided by 27 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 3252060.8518
Deduct 216 from 230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
27 goes into 140 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 3252060.85185
Deduct 135 from 140 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
When dividing 50 by 27, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 3252060.851851
Subtract 27 from 50 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 15:
230 divided by 27 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 3252060.8518518
Deduct 216 from 230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 16:
140 divided by 27 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3252060.85185185
If we take 135 away from 140, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.
