7838863 ÷ 216 
The aim is to understand the frequency of 216 in 7838863.

Advancing to step 1:
216 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 216

Moving on to step 2:
216 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 216

Going ahead to step 3:
The number 216 fits into 783 3 times, leaving a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 648 from 783 to get 135.
Grab the next digit (8) from the dividend, add it to 135, then carry on: 1358 / 216

Moving on to step 4:
If we divide 1358 by 216, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 1296 from 1358 to get 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 216

Going ahead to step 5:
628 divided by 216 is 2 with a remainder of 196.
The next digit of our result is 2. 
Result so far: 362.0
Deduct 432 from 628 and we're left with 196.
Bring next digit (6) of the dividend behind the 196 and repeat the process: 1966 / 216

Let's proceed to step 6:
If we divide 1966 by 216, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 3629.0
Subtracting 1944 from 1966 leaves us with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 216

Moving on to step 7:
223 divided by 216 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 36291.0
If we subtract 216 from 223, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
216 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 36291.0
Subtract 0 from 70 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.

Going ahead to step 9:
216 can be fit into 700 3 times, resulting in a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 36291.03
Subtracting 648 from 700 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.

Advancing to step 10:
If we divide 520 by 216, we get 2 and a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 36291.032
Subtracting 432 from 520 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
The number 216 fits into 880 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 36291.0324
If we take 864 away from 880, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
216 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 36291.0324
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
216 can be fit into 1600 7 times, resulting in a remainder of 88.
Record the quotient 7 as the next digit in the result. 
Result so far: 36291.032407
If we subtract 1512 from 1600, 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.

Let's proceed to step 14:
880 divided by 216 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 36291.0324074
Subtracting 864 from 880 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
216 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 36291.0324074
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 36291.0324074, and the remainder is 1.6e-07.
