We're dividing 73213359 by 216 
The aim is to understand the frequency of 216 in 73213359.

Advancing to step 1:
When dividing 7 by 216, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 216

Going ahead to step 2:
If we divide 73 by 216, we get 0 and a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 216

Advancing to step 3:
If we divide 732 by 216, we get 3 and a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 84 after subtracting 648 from 732.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 216

Advancing to step 4:
The number 216 fits into 841 3 times, leaving a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 648 from 841 to get 193.
Grab the next digit (3) from the dividend, add it to 193, then carry on: 1933 / 216

On to step 5:
When dividing 1933 by 216, we get 8 with a remainder of 205.
The next digit of our result is 8. 
Result so far: 338.0
If we take 1728 away from 1933, we end up with 205.
Include the next digit (3) from the dividend after 205, then repeat: 2053 / 216

Let's proceed to step 6:
216 goes into 2053 9 times with a remainder of 109.
Put 9 as the next digit of the answer. 
Result so far: 3389.0
If we take 1944 away from 2053, we end up with 109.
Grab the next digit (5) from the dividend, add it to 109, then carry on: 1095 / 216

Moving on to step 7:
If we divide 1095 by 216, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 33895.0
Deduct 1080 from 1095 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 216

Advancing to step 8:
159 divided by 216 is 0 with a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 338950.0
If we take 0 away from 159, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 9:
If we divide 1590 by 216, we get 7 and a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 338950.7
Deduct 1512 from 1590 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 10:
216 goes into 780 3 times with a remainder of 132.
Use 3 as the next digit of our solution. 
Result so far: 338950.73
If we take 648 away from 780, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 11:
1320 divided by 216 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 338950.736
Deduct 1296 from 1320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
216 goes into 240 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 338950.7361
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
If we divide 240 by 216, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 338950.73611
If we subtract 216 from 240, 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.

In conclusion, the division gives 338950.73611 with a balance of 2.4e-05.
