We divide 31539574 by 216
The aim is to understand the frequency of 216 in 31539574.

Going ahead to step 1:
If we divide 3 by 216, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 216

Moving on to step 2:
The number 216 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 216

Let's proceed to step 3:
The number 216 fits into 315 1 times, leaving a remainder of 99.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 216 from 315 leaves us with 99.
Bring next digit (3) of the dividend behind the 99 and repeat the process: 993 / 216

Advancing to step 4:
993 divided by 216 is 4 with a remainder of 129.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 864 from 993 leaves us with 129.
Grab the next digit (9) from the dividend, add it to 129, then carry on: 1299 / 216

Step 5:
216 can be fit into 1299 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 146.0
Deduct 1296 from 1299 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 216

Going ahead to step 6:
216 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 1460.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 216

On to step 7:
The number 216 fits into 357 1 times, leaving a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 14601.0
If we take 216 away from 357, we end up with 141.
Include the next digit (4) from the dividend after 141, then repeat: 1414 / 216

Let's proceed to step 8:
216 goes into 1414 6 times with a remainder of 118.
Put 6 as the next digit of the answer. 
Result so far: 146016.0
Subtract 1296 from 1414 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
When dividing 1180 by 216, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 146016.5
Deduct 1080 from 1180 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
When dividing 1000 by 216, we get 4 with a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 146016.54
Subtracting 864 from 1000 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.

Going ahead to step 11:
216 goes into 1360 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 146016.546
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.

Step 12:
The number 216 fits into 640 2 times, leaving a remainder of 208.
The next digit of our result is 2. 
Result so far: 146016.5462
If we take 432 away from 640, 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.

Going ahead to step 13:
216 can be fit into 2080 9 times, resulting in a remainder of 136.
Use 9 as the next digit of our solution. 
Result so far: 146016.54629
The remainder is 136 after subtracting 1944 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 14:
When dividing 1360 by 216, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 146016.546296
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 15:
640 divided by 216 is 2 with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 146016.5462962
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 16:
When dividing 2080 by 216, we get 9 with a remainder of 136.
Put 9 as the next digit of the answer. 
Result so far: 146016.54629629
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.

The quotient of the division is 146016.54629629, and the remainder is 1.36e-07.
