We're dividing 53647379 by 320 
The aim is to understand the frequency of 320 in 53647379.

Step 1:
5 divided by 320 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 320

Moving on to step 2:
When dividing 53 by 320, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 320

Moving on to step 3:
536 divided by 320 is 1 with a remainder of 216.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 320 from 536 and we're left with 216.
Include the next digit (4) from the dividend after 216, then repeat: 2164 / 320

Advancing to step 4:
If we divide 2164 by 320, we get 6 and a remainder of 244.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 244 after subtracting 1920 from 2164.
Take the next digit (7) from the dividend and append it to 244, then repeat: 2447 / 320

Moving on to step 5:
If we divide 2447 by 320, we get 7 and a remainder of 207.
Write down 7 as next digit of the result. 
Result so far: 167.0
Subtract 2240 from 2447 to get 207.
Fetch the next digit (3) from the dividend, attach it to 207 and continue: 2073 / 320

On to step 6:
2073 divided by 320 is 6 with a remainder of 153.
Use 6 as the next digit of our solution. 
Result so far: 1676.0
Deduct 1920 from 2073 and we're left with 153.
Fetch the next digit (7) from the dividend, attach it to 153 and continue: 1537 / 320

Moving on to step 7:
320 can be fit into 1537 4 times, resulting in a remainder of 257.
Put 4 as the next digit of the answer. 
Result so far: 16764.0
If we take 1280 away from 1537, we end up with 257.
Bring next digit (9) of the dividend behind the 257 and repeat the process: 2579 / 320

On to step 8:
2579 divided by 320 is 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 167648.0
If we subtract 2560 from 2579, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
320 can be fit into 190 0 times, resulting in a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 167648.0
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
The number 320 fits into 1900 5 times, leaving a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 167648.05
Subtracting 1600 from 1900 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
320 goes into 3000 9 times with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 167648.059
If we take 2880 away from 3000, 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 12:
When dividing 1200 by 320, we get 3 with a remainder of 240.
Write down 3 as next digit of the result. 
Result so far: 167648.0593
If we take 960 away from 1200, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
The number 320 fits into 2400 7 times, leaving a remainder of 160.
The next digit of our result is 7. 
Result so far: 167648.05937
If we take 2240 away from 2400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
320 goes into 1600 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 167648.059375
Subtracting 1600 from 1600 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.

Moving on to step 15:
320 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 167648.059375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 16:
320 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 167648.059375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 167648.059375 and a remainder of 0.0.
