We're dividing 77141751 by 320 
The aim is to understand the frequency of 320 in 77141751.

Step 1:
320 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 320

On to step 2:
If we divide 77 by 320, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 320

Moving on to step 3:
When dividing 771 by 320, we get 2 with a remainder of 131.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 640 away from 771, we end up with 131.
Take the next digit (4) from the dividend and append it to 131, then repeat: 1314 / 320

On to step 4:
If we divide 1314 by 320, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 1280 away from 1314, we end up with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 320

Advancing to step 5:
320 can be fit into 341 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 241.0
If we take 320 away from 341, we end up with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 320

Advancing to step 6:
When dividing 217 by 320, we get 0 with a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 2410.0
Subtract 0 from 217 to get 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 320

Advancing to step 7:
2175 divided by 320 is 6 with a remainder of 255.
Use 6 as the next digit of our solution. 
Result so far: 24106.0
Subtract 1920 from 2175 to get 255.
Grab the next digit (1) from the dividend, add it to 255, then carry on: 2551 / 320

Step 8:
2551 divided by 320 is 7 with a remainder of 311.
Record the quotient 7 as the next digit in the result. 
Result so far: 241067.0
Subtracting 2240 from 2551 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 9:
320 can be fit into 3110 9 times, resulting in a remainder of 230.
Record the quotient 9 as the next digit in the result. 
Result so far: 241067.9
If we take 2880 away from 3110, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
320 goes into 2300 7 times with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 241067.97
The remainder is 60 after subtracting 2240 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 320 fits into 600 1 times, leaving a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 241067.971
If we take 320 away from 600, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
If we divide 2800 by 320, we get 8 and a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 241067.9718
Deduct 2560 from 2800 and we're left 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.

On to step 13:
When dividing 2400 by 320, we get 7 with a remainder of 160.
Put 7 as the next digit of the answer. 
Result so far: 241067.97187
The remainder is 160 after subtracting 2240 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
1600 divided by 320 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 241067.971875
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.

Going ahead to step 15:
If we divide 0 by 320, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 241067.971875
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.

Advancing to step 16:
320 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 241067.971875
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.

The final result is 241067.971875 with a remainder of 0.0.
