Let's divide 21059 by 68
The aim is to understand the frequency of 68 in 21059.

Step 1:
When dividing 2 by 68, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 68

Going ahead to step 2:
If we divide 21 by 68, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 68

Moving on to step 3:
68 goes into 210 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 204 from 210 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 68

Going ahead to step 4:
When dividing 65 by 68, we get 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 68

Moving on to step 5:
The number 68 fits into 659 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 309.0
If we subtract 612 from 659, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 6:
68 goes into 470 6 times with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 309.6
The remainder is 62 after subtracting 408 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
620 divided by 68 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 309.69
If we subtract 612 from 620, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
80 divided by 68 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 309.691
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
68 can be fit into 120 1 times, resulting in a remainder of 52.
The next digit of our result is 1. 
Result so far: 309.6911
If we take 68 away from 120, we end up with 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 quotient of the division is 309.6911, and the remainder is 0.00052.
