We look at the division of 6315814 by 218 
The aim is to understand the frequency of 218 in 6315814.

Going ahead to step 1:
218 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 218

Advancing to step 2:
218 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 218

On to step 3:
The number 218 fits into 631 2 times, leaving a remainder of 195.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 436 from 631 leaves us with 195.
Include the next digit (5) from the dividend after 195, then repeat: 1955 / 218

On to step 4:
218 can be fit into 1955 8 times, resulting in a remainder of 211.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 1744 from 1955 leaves us with 211.
Grab the next digit (8) from the dividend, add it to 211, then carry on: 2118 / 218

Advancing to step 5:
2118 divided by 218 is 9 with a remainder of 156.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Deduct 1962 from 2118 and we're left with 156.
Include the next digit (1) from the dividend after 156, then repeat: 1561 / 218

Moving on to step 6:
If we divide 1561 by 218, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 2897.0
If we subtract 1526 from 1561, we get 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 218

Going ahead to step 7:
218 goes into 354 1 times with a remainder of 136.
The number 1 becomes the next digit in our result. 
Result so far: 28971.0
Subtract 218 from 354 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 8:
218 can be fit into 1360 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 28971.6
Subtracting 1308 from 1360 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
218 goes into 520 2 times with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 28971.62
Deduct 436 from 520 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
840 divided by 218 is 3 with a remainder of 186.
The number 3 becomes the next digit in our result. 
Result so far: 28971.623
Subtracting 654 from 840 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 11:
If we divide 1860 by 218, we get 8 and a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 28971.6238
If we take 1744 away from 1860, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 12:
218 goes into 1160 5 times with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 28971.62385
Subtract 1090 from 1160 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
If we divide 700 by 218, we get 3 and a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 28971.623853
Subtracting 654 from 700 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
When dividing 460 by 218, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 28971.6238532
If we subtract 436 from 460, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
218 can be fit into 240 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 28971.62385321
If we take 218 away from 240, we end up 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.

Our division results in 28971.62385321 with a remaining 2.2e-08.
