23316094 divided by 399 
The aim is to understand the frequency of 399 in 23316094.

Going ahead to step 1:
The number 399 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 399

Step 2:
399 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 399

Step 3:
399 goes into 233 0 times with a remainder of 233.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 233 and we're left with 233.
Bring next digit (1) of the dividend behind the 233 and repeat the process: 2331 / 399

Step 4:
If we divide 2331 by 399, we get 5 and a remainder of 336.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 1995 from 2331 and we're left with 336.
Append the next digit (6) from the dividend to 336 and continue with: 3366 / 399

Moving on to step 5:
If we divide 3366 by 399, we get 8 and a remainder of 174.
Put 8 as the next digit of the answer. 
Result so far: 58.0
The remainder is 174 after subtracting 3192 from 3366.
Take the next digit (0) from the dividend and append it to 174, then repeat: 1740 / 399

Advancing to step 6:
399 goes into 1740 4 times with a remainder of 144.
The next digit of our result is 4. 
Result so far: 584.0
If we subtract 1596 from 1740, we get 144.
Include the next digit (9) from the dividend after 144, then repeat: 1449 / 399

Going ahead to step 7:
If we divide 1449 by 399, we get 3 and a remainder of 252.
Use 3 as the next digit of our solution. 
Result so far: 5843.0
If we subtract 1197 from 1449, we get 252.
Bring next digit (4) of the dividend behind the 252 and repeat the process: 2524 / 399

Let's proceed to step 8:
399 can be fit into 2524 6 times, resulting in a remainder of 130.
Record the quotient 6 as the next digit in the result. 
Result so far: 58436.0
Subtracting 2394 from 2524 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
399 goes into 1300 3 times with a remainder of 103.
The next digit of our result is 3. 
Result so far: 58436.3
Subtracting 1197 from 1300 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 10:
1030 divided by 399 is 2 with a remainder of 232.
The next digit of our result is 2. 
Result so far: 58436.32
The remainder is 232 after subtracting 798 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
399 goes into 2320 5 times with a remainder of 325.
The next digit of our result is 5. 
Result so far: 58436.325
The remainder is 325 after subtracting 1995 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 12:
The number 399 fits into 3250 8 times, leaving a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 58436.3258
Subtract 3192 from 3250 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
When dividing 580 by 399, we get 1 with a remainder of 181.
Put 1 as the next digit of the answer. 
Result so far: 58436.32581
Deduct 399 from 580 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 14:
When dividing 1810 by 399, we get 4 with a remainder of 214.
Use 4 as the next digit of our solution. 
Result so far: 58436.325814
The remainder is 214 after subtracting 1596 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 15:
399 can be fit into 2140 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 58436.3258145
Subtracting 1995 from 2140 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 16:
1450 divided by 399 is 3 with a remainder of 253.
The next digit of our result is 3. 
Result so far: 58436.32581453
The remainder is 253 after subtracting 1197 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

After the division, we end up with 58436.32581453 and a remainder of 2.53e-07.
