Let's divide 21737902 by 440
The aim is to understand the frequency of 440 in 21737902.

Advancing to step 1:
440 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 440

On to step 2:
440 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 440

On to step 3:
217 divided by 440 is 0 with a remainder of 217.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 217, we get 217.
Grab the next digit (3) from the dividend, add it to 217, then carry on: 2173 / 440

Let's proceed to step 4:
2173 divided by 440 is 4 with a remainder of 413.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 413 after subtracting 1760 from 2173.
Fetch the next digit (7) from the dividend, attach it to 413 and continue: 4137 / 440

On to step 5:
If we divide 4137 by 440, we get 9 and a remainder of 177.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 3960 away from 4137, we end up with 177.
Take the next digit (9) from the dividend and append it to 177, then repeat: 1779 / 440

Going ahead to step 6:
When dividing 1779 by 440, we get 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 494.0
Deduct 1760 from 1779 and we're left with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 440

Step 7:
If we divide 190 by 440, we get 0 and a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 4940.0
Deduct 0 from 190 and we're left with 190.
Fetch the next digit (2) from the dividend, attach it to 190 and continue: 1902 / 440

On to step 8:
1902 divided by 440 is 4 with a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 49404.0
Subtract 1760 from 1902 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
440 can be fit into 1420 3 times, resulting in a remainder of 100.
The next digit of our result is 3. 
Result so far: 49404.3
The remainder is 100 after subtracting 1320 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
If we divide 1000 by 440, we get 2 and a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 49404.32
If we take 880 away from 1000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
When dividing 1200 by 440, we get 2 with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 49404.322
If we take 880 away from 1200, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 49404.322, with a leftover of 0.032.
