21802770 ÷ 364 
The aim is to understand the frequency of 364 in 21802770.

Step 1:
When dividing 2 by 364, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 364

Step 2:
364 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 364

Moving on to step 3:
364 can be fit into 218 0 times, resulting in a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 218 after subtracting 0 from 218.
Bring next digit (0) of the dividend behind the 218 and repeat the process: 2180 / 364

Going ahead to step 4:
If we divide 2180 by 364, we get 5 and a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 1820 from 2180 and we're left with 360.
Take the next digit (2) from the dividend and append it to 360, then repeat: 3602 / 364

Going ahead to step 5:
When dividing 3602 by 364, we get 9 with a remainder of 326.
The next digit of our result is 9. 
Result so far: 59.0
If we take 3276 away from 3602, we end up with 326.
Append the next digit (7) from the dividend to 326 and continue with: 3267 / 364

Going ahead to step 6:
The number 364 fits into 3267 8 times, leaving a remainder of 355.
Put 8 as the next digit of the answer. 
Result so far: 598.0
Subtract 2912 from 3267 to get 355.
Fetch the next digit (7) from the dividend, attach it to 355 and continue: 3557 / 364

Moving on to step 7:
If we divide 3557 by 364, we get 9 and a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 5989.0
Deduct 3276 from 3557 and we're left with 281.
Take the next digit (0) from the dividend and append it to 281, then repeat: 2810 / 364

Advancing to step 8:
The number 364 fits into 2810 7 times, leaving a remainder of 262.
The next digit of our result is 7. 
Result so far: 59897.0
The remainder is 262 after subtracting 2548 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 9:
364 goes into 2620 7 times with a remainder of 72.
The next digit of our result is 7. 
Result so far: 59897.7
The remainder is 72 after subtracting 2548 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
364 can be fit into 720 1 times, resulting in a remainder of 356.
The number 1 becomes the next digit in our result. 
Result so far: 59897.71
If we take 364 away from 720, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 11:
3560 divided by 364 is 9 with a remainder of 284.
Use 9 as the next digit of our solution. 
Result so far: 59897.719
If we subtract 3276 from 3560, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 12:
2840 divided by 364 is 7 with a remainder of 292.
Record the quotient 7 as the next digit in the result. 
Result so far: 59897.7197
If we take 2548 away from 2840, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 13:
2920 divided by 364 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 59897.71978
Subtracting 2912 from 2920 leaves us 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.

Going ahead to step 14:
If we divide 80 by 364, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 59897.71978
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
364 goes into 800 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 59897.7197802
Subtract 728 from 800 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 16:
When dividing 720 by 364, we get 1 with a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 59897.71978021
If we take 364 away from 720, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final result is 59897.71978021 with a remainder of 3.56e-07.
