Let's divide 541153 by 21
The aim is to understand the frequency of 21 in 541153.

Going ahead to step 1:
21 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 21

Advancing to step 2:
54 divided by 21 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 54, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 21

Moving on to step 3:
21 goes into 121 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 25.0
Subtracting 105 from 121 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 21

Going ahead to step 4:
If we divide 161 by 21, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtract 147 from 161 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 21

Let's proceed to step 5:
21 goes into 145 6 times with a remainder of 19.
The next digit of our result is 6. 
Result so far: 2576.0
If we take 126 away from 145, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 21

Going ahead to step 6:
21 goes into 193 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 25769.0
The remainder is 4 after subtracting 189 from 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 25769.1
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 25769.19
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 25769.19
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
21 goes into 100 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 25769.1904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 25769.19047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 25769.190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 25769.1904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 25769.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 25769.19047619 and a remainder of 1e-09.
