950482 divided by 21 
The aim is to understand the frequency of 21 in 950482.

Step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 21

Let's proceed to step 2:
The number 21 fits into 95 4 times, leaving a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 84 from 95 and we're left with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 21

Let's proceed to step 3:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 105 from 110, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 21

On to step 4:
The number 21 fits into 54 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 452.0
The remainder is 12 after subtracting 42 from 54.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 21

Going ahead to step 5:
21 goes into 128 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 4526.0
Subtracting 126 from 128 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 21

Going ahead to step 6:
22 divided by 21 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 45261.0
Subtract 21 from 22 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 45261.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 45261.04
If we subtract 84 from 100, we 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 9:
160 divided by 21 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 45261.047
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.

Advancing to step 10:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 45261.0476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 45261.04761
Subtracting 21 from 40 leaves us with 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 12:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 45261.047619
Subtracting 189 from 190 leaves us 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.

Advancing to step 13:
21 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 45261.047619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 45261.04761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 45261.04761904 with a remaining 1.6e-08.
