86791983 divided by 320 
The aim is to understand the frequency of 320 in 86791983.

Advancing to step 1:
When dividing 8 by 320, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 320

Advancing to step 2:
320 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 320

Step 3:
When dividing 867 by 320, we get 2 with a remainder of 227.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 640 away from 867, we end up with 227.
Fetch the next digit (9) from the dividend, attach it to 227 and continue: 2279 / 320

On to step 4:
2279 divided by 320 is 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 2240 from 2279, we get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 320

Step 5:
391 divided by 320 is 1 with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 271.0
Deduct 320 from 391 and we're left with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 320

Let's proceed to step 6:
The number 320 fits into 719 2 times, leaving a remainder of 79.
Use 2 as the next digit of our solution. 
Result so far: 2712.0
Deduct 640 from 719 and we're left with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 320

Going ahead to step 7:
320 goes into 798 2 times with a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 27122.0
Subtracting 640 from 798 leaves us with 158.
Bring next digit (3) of the dividend behind the 158 and repeat the process: 1583 / 320

Going ahead to step 8:
1583 divided by 320 is 4 with a remainder of 303.
Record the quotient 4 as the next digit in the result. 
Result so far: 271224.0
Subtracting 1280 from 1583 leaves us with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 9:
If we divide 3030 by 320, we get 9 and a remainder of 150.
Use 9 as the next digit of our solution. 
Result so far: 271224.9
If we take 2880 away from 3030, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
320 can be fit into 1500 4 times, resulting in a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 271224.94
Deduct 1280 from 1500 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
2200 divided by 320 is 6 with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 271224.946
Deduct 1920 from 2200 and we're left 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.

On to step 12:
If we divide 2800 by 320, we get 8 and a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 271224.9468
Subtract 2560 from 2800 to get 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:
The number 320 fits into 2400 7 times, leaving a remainder of 160.
Write down 7 as next digit of the result. 
Result so far: 271224.94687
If we subtract 2240 from 2400, we get 160.
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 14:
320 goes into 1600 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 271224.946875
If we subtract 1600 from 1600, 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.

On to step 15:
0 divided by 320 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 271224.946875
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 16:
320 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 271224.946875
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.

In conclusion, the division gives 271224.946875 with a balance of 0.0.
