Let's divide 955175 by 21
The aim is to understand the frequency of 21 in 955175.

Let's proceed to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 21

Step 2:
When dividing 95 by 21, we get 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 84 from 95 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 21

Moving on to step 3:
If we divide 115 by 21, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 105 from 115 leaves us with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 21

On to step 4:
If we divide 101 by 21, we get 4 and a remainder of 17.
The next digit of our result is 4. 
Result so far: 454.0
Subtract 84 from 101 to get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 21

Advancing to step 5:
If we divide 177 by 21, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 4548.0
If we take 168 away from 177, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 21

Going ahead to step 6:
When dividing 95 by 21, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 45484.0
Subtracting 84 from 95 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 45484.5
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 45484.52
If we subtract 42 from 50, 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 9:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 45484.523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 45484.5238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
21 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 45484.5238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 21, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 45484.523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 45484.5238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 45484.52380952
If we subtract 42 from 50, 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.

The quotient of the division is 45484.52380952, and the remainder is 8e-09.
