We're dividing 32055286 by 21 
The aim is to understand the frequency of 21 in 32055286.

Let's proceed to step 1:
3 divided by 21 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 21

On to step 2:
If we divide 32 by 21, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 21 from 32 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 21

Let's proceed to step 3:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 105 from 110 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 21

Going ahead to step 4:
The number 21 fits into 55 2 times, leaving a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Deduct 42 from 55 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 21

Going ahead to step 5:
The number 21 fits into 135 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 1526.0
The remainder is 9 after subtracting 126 from 135.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 21

Let's proceed to step 6:
21 can be fit into 92 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 15264.0
Subtract 84 from 92 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 21

On to step 7:
21 can be fit into 88 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 152644.0
If we take 84 away from 88, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 21

On to step 8:
21 goes into 46 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1526442.0
Subtract 42 from 46 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.

Step 9:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1526442.1
If we take 21 away from 40, we end up 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.

Advancing to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1526442.19
Deduct 189 from 190 and we're left 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.

On to step 11:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1526442.19
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1526442.1904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
21 goes into 160 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 1526442.19047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1526442.190476
If we take 126 away from 130, we end up 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.

Advancing to step 15:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1526442.1904761
If we take 21 away from 40, we end up 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.

Step 16:
If we divide 190 by 21, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1526442.19047619
Subtract 189 from 190 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.

The quotient of the division is 1526442.19047619, and the remainder is 1e-09.
