Let's divide 694769 by 21
The aim is to understand the frequency of 21 in 694769.

Advancing to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 21

Moving on to step 2:
When dividing 69 by 21, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 63 from 69, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 21

Advancing to step 3:
If we divide 64 by 21, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 63 away from 64, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 21

On to step 4:
21 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 330.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 21

Moving on to step 5:
176 divided by 21 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3308.0
Deduct 168 from 176 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 21

Advancing to step 6:
21 can be fit into 89 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 33084.0
If we subtract 84 from 89, 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.

Advancing to step 7:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 33084.2
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.

On to step 8:
When dividing 80 by 21, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 33084.23
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 33084.238
Deduct 168 from 170 and we're left 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 10:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 33084.238
Deduct 0 from 20 and we're left 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.

Going ahead to step 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 33084.23809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 33084.238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
50 divided by 21 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 33084.2380952
If we take 42 away from 50, we end up 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.

Moving on to step 14:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 33084.23809523
Subtracting 63 from 80 leaves us 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.

Our division results in 33084.23809523 with a remaining 1.7e-08.
