We divide 67011 by 21
The aim is to understand the frequency of 21 in 67011.

Going ahead to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 21

Going ahead to step 2:
21 goes into 67 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 63 from 67 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 21

Let's proceed to step 3:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 21 from 40 to get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 21

Step 4:
The number 21 fits into 191 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 319.0
Subtract 189 from 191 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 21

Going ahead to step 5:
21 divided by 21 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 3191.0
Deduct 21 from 21 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 6:
If we divide 0 by 21, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3191.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3191.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 3191.0 with a balance of 0.0.
