53888845 ÷ 320 
The aim is to understand the frequency of 320 in 53888845.

Moving on to step 1:
The number 320 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 320

Moving on to step 2:
If we divide 53 by 320, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 320

Let's proceed to step 3:
When dividing 538 by 320, we get 1 with a remainder of 218.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 320 from 538 to get 218.
Take the next digit (8) from the dividend and append it to 218, then repeat: 2188 / 320

Let's proceed to step 4:
2188 divided by 320 is 6 with a remainder of 268.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 268 after subtracting 1920 from 2188.
Fetch the next digit (8) from the dividend, attach it to 268 and continue: 2688 / 320

On to step 5:
320 goes into 2688 8 times with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Deduct 2560 from 2688 and we're left with 128.
Append the next digit (8) from the dividend to 128 and continue with: 1288 / 320

Moving on to step 6:
320 can be fit into 1288 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1684.0
The remainder is 8 after subtracting 1280 from 1288.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 320

Moving on to step 7:
84 divided by 320 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 16840.0
Subtracting 0 from 84 leaves us with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 320

On to step 8:
320 goes into 845 2 times with a remainder of 205.
Put 2 as the next digit of the answer. 
Result so far: 168402.0
If we take 640 away from 845, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
2050 divided by 320 is 6 with a remainder of 130.
The next digit of our result is 6. 
Result so far: 168402.6
The remainder is 130 after subtracting 1920 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
320 goes into 1300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 168402.64
Subtracting 1280 from 1300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 320 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 168402.64
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
The number 320 fits into 2000 6 times, leaving a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 168402.6406
Subtract 1920 from 2000 to 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.

Going ahead to step 13:
If we divide 800 by 320, we get 2 and a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 168402.64062
Subtracting 640 from 800 leaves us 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.

Step 14:
The number 320 fits into 1600 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 168402.640625
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.

On to step 15:
0 divided by 320 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 168402.640625
Deduct 0 from 0 and we're left 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.

Advancing to step 16:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 168402.640625
Deduct 0 from 0 and we're left 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 quotient of the division is 168402.640625, and the remainder is 0.0.
