Let's divide 106547 by 21
The aim is to understand the frequency of 21 in 106547.

Moving on to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 21

Let's proceed to step 2:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 21

Moving on to step 3:
106 divided by 21 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 105 from 106 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 21

Going ahead to step 4:
15 divided by 21 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 21

Moving on to step 5:
When dividing 154 by 21, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 507.0
If we take 147 away from 154, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 21

Going ahead to step 6:
The number 21 fits into 77 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 5073.0
Deduct 63 from 77 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 21, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 5073.6
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 21, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 5073.66
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 5073.66, with a leftover of 0.014.
