We look at the division of 80395519 by 227 
The aim is to understand the frequency of 227 in 80395519.

On to step 1:
If we divide 8 by 227, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 227

Step 2:
80 divided by 227 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 227

On to step 3:
The number 227 fits into 803 3 times, leaving a remainder of 122.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 681 from 803 and we're left with 122.
Include the next digit (9) from the dividend after 122, then repeat: 1229 / 227

Step 4:
The number 227 fits into 1229 5 times, leaving a remainder of 94.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we subtract 1135 from 1229, we get 94.
Fetch the next digit (5) from the dividend, attach it to 94 and continue: 945 / 227

On to step 5:
227 goes into 945 4 times with a remainder of 37.
The next digit of our result is 4. 
Result so far: 354.0
If we take 908 away from 945, we end up with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 227

Moving on to step 6:
If we divide 375 by 227, we get 1 and a remainder of 148.
The next digit of our result is 1. 
Result so far: 3541.0
If we take 227 away from 375, we end up with 148.
Grab the next digit (1) from the dividend, add it to 148, then carry on: 1481 / 227

Step 7:
227 can be fit into 1481 6 times, resulting in a remainder of 119.
Use 6 as the next digit of our solution. 
Result so far: 35416.0
If we take 1362 away from 1481, we end up with 119.
Append the next digit (9) from the dividend to 119 and continue with: 1199 / 227

Let's proceed to step 8:
The number 227 fits into 1199 5 times, leaving a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 354165.0
Subtract 1135 from 1199 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
When dividing 640 by 227, we get 2 with a remainder of 186.
Put 2 as the next digit of the answer. 
Result so far: 354165.2
The remainder is 186 after subtracting 454 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
227 goes into 1860 8 times with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 354165.28
Deduct 1816 from 1860 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
227 goes into 440 1 times with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 354165.281
If we take 227 away from 440, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 12:
If we divide 2130 by 227, we get 9 and a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 354165.2819
Deduct 2043 from 2130 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 13:
If we divide 870 by 227, we get 3 and a remainder of 189.
Record the quotient 3 as the next digit in the result. 
Result so far: 354165.28193
The remainder is 189 after subtracting 681 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 14:
The number 227 fits into 1890 8 times, leaving a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 354165.281938
If we subtract 1816 from 1890, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 15:
The number 227 fits into 740 3 times, leaving a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 354165.2819383
The remainder is 59 after subtracting 681 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 16:
The number 227 fits into 590 2 times, leaving a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 354165.28193832
Deduct 454 from 590 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 354165.28193832 with a remainder of 1.36e-07.
