Let's divide 21022323 by 478
The aim is to understand the frequency of 478 in 21022323.

Going ahead to step 1:
If we divide 2 by 478, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 478

Moving on to step 2:
21 divided by 478 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 478

Let's proceed to step 3:
The number 478 fits into 210 0 times, leaving a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (2) from the dividend, add it to 210, then carry on: 2102 / 478

Moving on to step 4:
The number 478 fits into 2102 4 times, leaving a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 1912 from 2102 leaves us with 190.
Fetch the next digit (2) from the dividend, attach it to 190 and continue: 1902 / 478

Going ahead to step 5:
1902 divided by 478 is 3 with a remainder of 468.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 468 after subtracting 1434 from 1902.
Grab the next digit (3) from the dividend, add it to 468, then carry on: 4683 / 478

Step 6:
478 can be fit into 4683 9 times, resulting in a remainder of 381.
Write down 9 as next digit of the result. 
Result so far: 439.0
Subtract 4302 from 4683 to get 381.
Bring next digit (2) of the dividend behind the 381 and repeat the process: 3812 / 478

On to step 7:
3812 divided by 478 is 7 with a remainder of 466.
Write down 7 as next digit of the result. 
Result so far: 4397.0
Subtract 3346 from 3812 to get 466.
Grab the next digit (3) from the dividend, add it to 466, then carry on: 4663 / 478

Going ahead to step 8:
When dividing 4663 by 478, we get 9 with a remainder of 361.
Record the quotient 9 as the next digit in the result. 
Result so far: 43979.0
The remainder is 361 after subtracting 4302 from 4663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 9:
478 goes into 3610 7 times with a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 43979.7
Subtract 3346 from 3610 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 10:
When dividing 2640 by 478, we get 5 with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 43979.75
Subtract 2390 from 2640 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
2500 divided by 478 is 5 with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 43979.755
If we take 2390 away from 2500, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 43979.755 with a remainder of 0.011.
