96846655 ÷ 390 
The aim is to understand the frequency of 390 in 96846655.

Moving on to step 1:
When dividing 9 by 390, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 390

On to step 2:
The number 390 fits into 96 0 times, leaving a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 96 leaves us with 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 390

Let's proceed to step 3:
When dividing 968 by 390, we get 2 with a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 780 from 968 and we're left with 188.
Fetch the next digit (4) from the dividend, attach it to 188 and continue: 1884 / 390

Advancing to step 4:
When dividing 1884 by 390, we get 4 with a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 1560 from 1884 and we're left with 324.
Append the next digit (6) from the dividend to 324 and continue with: 3246 / 390

Let's proceed to step 5:
When dividing 3246 by 390, we get 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
Subtract 3120 from 3246 to get 126.
Append the next digit (6) from the dividend to 126 and continue with: 1266 / 390

On to step 6:
390 can be fit into 1266 3 times, resulting in a remainder of 96.
Put 3 as the next digit of the answer. 
Result so far: 2483.0
If we take 1170 away from 1266, we end up with 96.
Include the next digit (5) from the dividend after 96, then repeat: 965 / 390

Going ahead to step 7:
965 divided by 390 is 2 with a remainder of 185.
Record the quotient 2 as the next digit in the result. 
Result so far: 24832.0
Deduct 780 from 965 and we're left with 185.
Grab the next digit (5) from the dividend, add it to 185, then carry on: 1855 / 390

Going ahead to step 8:
When dividing 1855 by 390, we get 4 with a remainder of 295.
The number 4 becomes the next digit in our result. 
Result so far: 248324.0
If we take 1560 away from 1855, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 9:
390 can be fit into 2950 7 times, resulting in a remainder of 220.
The next digit of our result is 7. 
Result so far: 248324.7
If we subtract 2730 from 2950, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
When dividing 2200 by 390, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 248324.75
The remainder is 250 after subtracting 1950 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
2500 divided by 390 is 6 with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 248324.756
Deduct 2340 from 2500 and we're left 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.

Let's proceed to step 12:
If we divide 1600 by 390, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 248324.7564
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
The number 390 fits into 400 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 248324.75641
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 390, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 248324.75641
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
If we divide 1000 by 390, we get 2 and a remainder of 220.
The next digit of our result is 2. 
Result so far: 248324.7564102
Subtract 780 from 1000 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
When dividing 2200 by 390, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 248324.75641025
If we subtract 1950 from 2200, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The quotient of the division is 248324.75641025, and the remainder is 2.5e-07.
