We look at the division of 4215583 by 216 
The aim is to understand the frequency of 216 in 4215583.

Going ahead to step 1:
216 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 216

Let's proceed to step 2:
When dividing 42 by 216, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 216

Going ahead to step 3:
The number 216 fits into 421 1 times, leaving a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 216 from 421 and we're left with 205.
Include the next digit (5) from the dividend after 205, then repeat: 2055 / 216

On to step 4:
When dividing 2055 by 216, we get 9 with a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 1944 from 2055 to get 111.
Take the next digit (5) from the dividend and append it to 111, then repeat: 1115 / 216

Moving on to step 5:
216 can be fit into 1115 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Deduct 1080 from 1115 and we're left with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 216

Advancing to step 6:
216 can be fit into 358 1 times, resulting in a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 1951.0
Subtract 216 from 358 to get 142.
Include the next digit (3) from the dividend after 142, then repeat: 1423 / 216

Let's proceed to step 7:
216 can be fit into 1423 6 times, resulting in a remainder of 127.
Record the quotient 6 as the next digit in the result. 
Result so far: 19516.0
Deduct 1296 from 1423 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 8:
1270 divided by 216 is 5 with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 19516.5
If we subtract 1080 from 1270, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
216 can be fit into 1900 8 times, resulting in a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 19516.58
Deduct 1728 from 1900 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 10:
When dividing 1720 by 216, we get 7 with a remainder of 208.
Record the quotient 7 as the next digit in the result. 
Result so far: 19516.587
If we take 1512 away from 1720, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
2080 divided by 216 is 9 with a remainder of 136.
The number 9 becomes the next digit in our result. 
Result so far: 19516.5879
Subtracting 1944 from 2080 leaves us with 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 12:
1360 divided by 216 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 19516.58796
If we subtract 1296 from 1360, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
216 can be fit into 640 2 times, resulting in a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 19516.587962
Subtracting 432 from 640 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 14:
216 can be fit into 2080 9 times, resulting in a remainder of 136.
The next digit of our result is 9. 
Result so far: 19516.5879629
Subtract 1944 from 2080 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.

Step 15:
The number 216 fits into 1360 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 19516.58796296
If we take 1296 away from 1360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 19516.58796296, and the remainder is 6.4e-08.
