99389238 divided by 358 
The aim is to understand the frequency of 358 in 99389238.

Going ahead to step 1:
The number 358 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 358

On to step 2:
When dividing 99 by 358, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Bring next digit (3) of the dividend behind the 99 and repeat the process: 993 / 358

Moving on to step 3:
993 divided by 358 is 2 with a remainder of 277.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 716 away from 993, we end up with 277.
Fetch the next digit (8) from the dividend, attach it to 277 and continue: 2778 / 358

Advancing to step 4:
The number 358 fits into 2778 7 times, leaving a remainder of 272.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 2506 from 2778 to get 272.
Bring next digit (9) of the dividend behind the 272 and repeat the process: 2729 / 358

Moving on to step 5:
The number 358 fits into 2729 7 times, leaving a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 277.0
If we take 2506 away from 2729, we end up with 223.
Take the next digit (2) from the dividend and append it to 223, then repeat: 2232 / 358

Let's proceed to step 6:
The number 358 fits into 2232 6 times, leaving a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 2776.0
If we subtract 2148 from 2232, we get 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 358

Moving on to step 7:
843 divided by 358 is 2 with a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 27762.0
If we subtract 716 from 843, we get 127.
Fetch the next digit (8) from the dividend, attach it to 127 and continue: 1278 / 358

Advancing to step 8:
1278 divided by 358 is 3 with a remainder of 204.
The number 3 becomes the next digit in our result. 
Result so far: 277623.0
If we take 1074 away from 1278, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 9:
2040 divided by 358 is 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 277623.5
The remainder is 250 after subtracting 1790 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
The number 358 fits into 2500 6 times, leaving a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 277623.56
Deduct 2148 from 2500 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 11:
358 can be fit into 3520 9 times, resulting in a remainder of 298.
The number 9 becomes the next digit in our result. 
Result so far: 277623.569
If we take 3222 away from 3520, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 12:
358 can be fit into 2980 8 times, resulting in a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 277623.5698
Deduct 2864 from 2980 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 13:
The number 358 fits into 1160 3 times, leaving a remainder of 86.
The next digit of our result is 3. 
Result so far: 277623.56983
If we subtract 1074 from 1160, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 14:
860 divided by 358 is 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 277623.569832
The remainder is 144 after subtracting 716 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 15:
The number 358 fits into 1440 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 277623.5698324
If we take 1432 away from 1440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
If we divide 80 by 358, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 277623.5698324
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 277623.5698324 with a balance of 8e-08.
