We look at the division of 51941810 by 218 
The aim is to understand the frequency of 218 in 51941810.

Moving on to step 1:
When dividing 5 by 218, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 218

Step 2:
When dividing 51 by 218, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 218

Let's proceed to step 3:
If we divide 519 by 218, we get 2 and a remainder of 83.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 436 from 519 and we're left with 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 218

Advancing to step 4:
834 divided by 218 is 3 with a remainder of 180.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 654 away from 834, we end up with 180.
Take the next digit (1) from the dividend and append it to 180, then repeat: 1801 / 218

Let's proceed to step 5:
218 goes into 1801 8 times with a remainder of 57.
The next digit of our result is 8. 
Result so far: 238.0
The remainder is 57 after subtracting 1744 from 1801.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 218

Moving on to step 6:
578 divided by 218 is 2 with a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 2382.0
The remainder is 142 after subtracting 436 from 578.
Grab the next digit (1) from the dividend, add it to 142, then carry on: 1421 / 218

Going ahead to step 7:
If we divide 1421 by 218, we get 6 and a remainder of 113.
Put 6 as the next digit of the answer. 
Result so far: 23826.0
If we take 1308 away from 1421, we end up with 113.
Fetch the next digit (0) from the dividend, attach it to 113 and continue: 1130 / 218

On to step 8:
If we divide 1130 by 218, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 238265.0
Deduct 1090 from 1130 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
218 can be fit into 400 1 times, resulting in a remainder of 182.
The next digit of our result is 1. 
Result so far: 238265.1
If we take 218 away from 400, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 10:
The number 218 fits into 1820 8 times, leaving a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 238265.18
Deduct 1744 from 1820 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
218 can be fit into 760 3 times, resulting in a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 238265.183
If we take 654 away from 760, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 12:
The number 218 fits into 1060 4 times, leaving a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 238265.1834
If we subtract 872 from 1060, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 13:
1880 divided by 218 is 8 with a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 238265.18348
If we subtract 1744 from 1880, we 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.

Step 14:
The number 218 fits into 1360 6 times, leaving a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 238265.183486
Subtract 1308 from 1360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 15:
218 goes into 520 2 times with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 238265.1834862
If we take 436 away from 520, we end up 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.

Let's proceed to step 16:
When dividing 840 by 218, we get 3 with a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 238265.18348623
Subtract 654 from 840 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

After the division, we end up with 238265.18348623 and a remainder of 1.86e-07.
