212440 divided by 68 
The aim is to understand the frequency of 68 in 212440.

Going ahead to step 1:
When dividing 2 by 68, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 68

On to step 2:
If we divide 21 by 68, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 68

On to step 3:
68 can be fit into 212 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 204 from 212 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 68

Step 4:
84 divided by 68 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 68 from 84 to get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 68

Let's proceed to step 5:
If we divide 164 by 68, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 312.0
If we subtract 136 from 164, we get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 68

Let's proceed to step 6:
280 divided by 68 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3124.0
If we take 272 away from 280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 68 fits into 80 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 3124.1
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
68 goes into 120 1 times with a remainder of 52.
The next digit of our result is 1. 
Result so far: 3124.11
Subtract 68 from 120 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 3124.11, with a leftover of 0.052.
