Let's divide 52721418 by 320
The aim is to understand the frequency of 320 in 52721418.

Going ahead to step 1:
If we divide 5 by 320, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 320

Going ahead to step 2:
If we divide 52 by 320, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 320

Advancing to step 3:
If we divide 527 by 320, we get 1 and a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 320 from 527 to get 207.
Include the next digit (2) from the dividend after 207, then repeat: 2072 / 320

Advancing to step 4:
320 can be fit into 2072 6 times, resulting in a remainder of 152.
The next digit of our result is 6. 
Result so far: 16.0
If we take 1920 away from 2072, we end up with 152.
Bring next digit (1) of the dividend behind the 152 and repeat the process: 1521 / 320

Let's proceed to step 5:
When dividing 1521 by 320, we get 4 with a remainder of 241.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we subtract 1280 from 1521, we get 241.
Bring next digit (4) of the dividend behind the 241 and repeat the process: 2414 / 320

Let's proceed to step 6:
When dividing 2414 by 320, we get 7 with a remainder of 174.
Use 7 as the next digit of our solution. 
Result so far: 1647.0
The remainder is 174 after subtracting 2240 from 2414.
Fetch the next digit (1) from the dividend, attach it to 174 and continue: 1741 / 320

Going ahead to step 7:
If we divide 1741 by 320, we get 5 and a remainder of 141.
The next digit of our result is 5. 
Result so far: 16475.0
The remainder is 141 after subtracting 1600 from 1741.
Take the next digit (8) from the dividend and append it to 141, then repeat: 1418 / 320

Step 8:
If we divide 1418 by 320, we get 4 and a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 164754.0
Subtracting 1280 from 1418 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
The number 320 fits into 1380 4 times, leaving a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 164754.4
The remainder is 100 after subtracting 1280 from 1380.
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:
320 can be fit into 1000 3 times, resulting in a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 164754.43
If we take 960 away from 1000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
320 goes into 400 1 times with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 164754.431
If we take 320 away from 400, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
320 can be fit into 800 2 times, resulting in a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 164754.4312
The remainder is 160 after subtracting 640 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
When dividing 1600 by 320, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 164754.43125
The remainder is 0 after subtracting 1600 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
The number 320 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 164754.43125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 164754.43125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 164754.43125, with a leftover of 0.0.
