99480475 ÷ 394 
The aim is to understand the frequency of 394 in 99480475.

Advancing to step 1:
If we divide 9 by 394, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 394

On to step 2:
394 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Append the next digit (4) from the dividend to 99 and continue with: 994 / 394

Advancing to step 3:
The number 394 fits into 994 2 times, leaving a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 788 from 994 and we're left with 206.
Include the next digit (8) from the dividend after 206, then repeat: 2068 / 394

Going ahead to step 4:
The number 394 fits into 2068 5 times, leaving a remainder of 98.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1970 from 2068 to get 98.
Bring next digit (0) of the dividend behind the 98 and repeat the process: 980 / 394

Advancing to step 5:
If we divide 980 by 394, we get 2 and a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Subtract 788 from 980 to get 192.
Grab the next digit (4) from the dividend, add it to 192, then carry on: 1924 / 394

Step 6:
394 goes into 1924 4 times with a remainder of 348.
Put 4 as the next digit of the answer. 
Result so far: 2524.0
Subtract 1576 from 1924 to get 348.
Append the next digit (7) from the dividend to 348 and continue with: 3487 / 394

Going ahead to step 7:
The number 394 fits into 3487 8 times, leaving a remainder of 335.
Use 8 as the next digit of our solution. 
Result so far: 25248.0
If we subtract 3152 from 3487, we get 335.
Append the next digit (5) from the dividend to 335 and continue with: 3355 / 394

Going ahead to step 8:
394 can be fit into 3355 8 times, resulting in a remainder of 203.
Record the quotient 8 as the next digit in the result. 
Result so far: 252488.0
If we subtract 3152 from 3355, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 9:
The number 394 fits into 2030 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 252488.5
Deduct 1970 from 2030 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
394 goes into 600 1 times with a remainder of 206.
The next digit of our result is 1. 
Result so far: 252488.51
The remainder is 206 after subtracting 394 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 11:
If we divide 2060 by 394, we get 5 and a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 252488.515
Subtract 1970 from 2060 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
900 divided by 394 is 2 with a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 252488.5152
If we take 788 away from 900, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 13:
394 goes into 1120 2 times with a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 252488.51522
If we take 788 away from 1120, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

In conclusion, the division gives 252488.51522 with a balance of 0.000332.
