69231521 divided by 218 
The aim is to understand the frequency of 218 in 69231521.

Advancing to step 1:
218 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 218

Step 2:
The number 218 fits into 69 0 times, leaving a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (2) from the dividend, attach it to 69 and continue: 692 / 218

Step 3:
If we divide 692 by 218, we get 3 and a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 654 away from 692, we end up with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 218

Moving on to step 4:
218 can be fit into 383 1 times, resulting in a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 218 away from 383, we end up with 165.
Take the next digit (1) from the dividend and append it to 165, then repeat: 1651 / 218

Advancing to step 5:
The number 218 fits into 1651 7 times, leaving a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Deduct 1526 from 1651 and we're left with 125.
Grab the next digit (5) from the dividend, add it to 125, then carry on: 1255 / 218

On to step 6:
When dividing 1255 by 218, we get 5 with a remainder of 165.
The next digit of our result is 5. 
Result so far: 3175.0
If we subtract 1090 from 1255, we get 165.
Take the next digit (2) from the dividend and append it to 165, then repeat: 1652 / 218

Let's proceed to step 7:
218 goes into 1652 7 times with a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 31757.0
If we take 1526 away from 1652, we end up with 126.
Grab the next digit (1) from the dividend, add it to 126, then carry on: 1261 / 218

Step 8:
The number 218 fits into 1261 5 times, leaving a remainder of 171.
Use 5 as the next digit of our solution. 
Result so far: 317575.0
Deduct 1090 from 1261 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 9:
1710 divided by 218 is 7 with a remainder of 184.
Use 7 as the next digit of our solution. 
Result so far: 317575.7
The remainder is 184 after subtracting 1526 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
The number 218 fits into 1840 8 times, leaving a remainder of 96.
The next digit of our result is 8. 
Result so far: 317575.78
If we take 1744 away from 1840, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
960 divided by 218 is 4 with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 317575.784
If we subtract 872 from 960, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 12:
880 divided by 218 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 317575.7844
Deduct 872 from 880 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 317575.7844 with a remainder of 8e-05.
