23216518 ÷ 212 
The aim is to understand the frequency of 212 in 23216518.

Moving on to step 1:
212 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 212

Going ahead to step 2:
When dividing 23 by 212, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 212

Step 3:
When dividing 232 by 212, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 212 from 232 leaves us with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 212

Moving on to step 4:
212 can be fit into 201 0 times, resulting in a remainder of 201.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 201 leaves us with 201.
Grab the next digit (6) from the dividend, add it to 201, then carry on: 2016 / 212

Step 5:
212 goes into 2016 9 times with a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 1908 from 2016 and we're left with 108.
Include the next digit (5) from the dividend after 108, then repeat: 1085 / 212

Advancing to step 6:
If we divide 1085 by 212, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1095.0
Subtract 1060 from 1085 to get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 212

Advancing to step 7:
251 divided by 212 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 10951.0
The remainder is 39 after subtracting 212 from 251.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 212

Let's proceed to step 8:
398 divided by 212 is 1 with a remainder of 186.
Use 1 as the next digit of our solution. 
Result so far: 109511.0
If we subtract 212 from 398, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
212 can be fit into 1860 8 times, resulting in a remainder of 164.
Use 8 as the next digit of our solution. 
Result so far: 109511.8
If we subtract 1696 from 1860, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
If we divide 1640 by 212, we get 7 and a remainder of 156.
Use 7 as the next digit of our solution. 
Result so far: 109511.87
Deduct 1484 from 1640 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
212 can be fit into 1560 7 times, resulting in a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 109511.877
If we subtract 1484 from 1560, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 109511.877 and a remainder of 0.0076.
