We divide 895358 by 21
The aim is to understand the frequency of 21 in 895358.

Let's proceed to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 21

Step 2:
89 divided by 21 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
If we take 84 away from 89, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 21

Going ahead to step 3:
21 can be fit into 55 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 42 from 55 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 21

Let's proceed to step 4:
133 divided by 21 is 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
Deduct 126 from 133 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 21

Going ahead to step 5:
75 divided by 21 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 4263.0
Subtract 63 from 75 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 21

On to step 6:
128 divided by 21 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 42636.0
The remainder is 2 after subtracting 126 from 128.
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 7:
If we divide 20 by 21, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 42636.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 42636.09
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.

Let's proceed to step 9:
If we divide 110 by 21, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 42636.095
If we subtract 105 from 110, we 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 10:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 42636.0952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
21 goes into 80 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 42636.09523
Deduct 63 from 80 and we're left 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.

On to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 42636.095238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 42636.095238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
21 goes into 200 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 42636.09523809
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.

After the division, we end up with 42636.09523809 and a remainder of 1.1e-08.
