We divide 416694 by 21
The aim is to understand the frequency of 21 in 416694.

Moving on to step 1:
21 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 21

Let's proceed to step 2:
21 can be fit into 41 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 21 from 41 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 21

Moving on to step 3:
When dividing 206 by 21, we get 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 189 from 206 and we're left with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 21

Let's proceed to step 4:
When dividing 176 by 21, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 198.0
Deduct 168 from 176 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 21

Going ahead to step 5:
When dividing 89 by 21, we get 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 1984.0
Subtracting 84 from 89 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 21

Moving on to step 6:
54 divided by 21 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 19842.0
If we take 42 away from 54, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 19842.5
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
If we divide 150 by 21, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 19842.57
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 21 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 19842.571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
21 goes into 90 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 19842.5714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 19842.57142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
When dividing 180 by 21, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 19842.571428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
If we divide 120 by 21, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 19842.5714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
21 goes into 150 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 19842.57142857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 19842.57142857 with a remainder of 3e-09.
