25111394 ÷ 230 
The aim is to understand the frequency of 230 in 25111394.

Going ahead to step 1:
If we divide 2 by 230, we get 0 and 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.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 230

Advancing to step 2:
230 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 230

On to step 3:
The number 230 fits into 251 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 230 from 251, we get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 230

Step 4:
The number 230 fits into 211 0 times, leaving a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 211 and we're left with 211.
Take the next digit (1) from the dividend and append it to 211, then repeat: 2111 / 230

Step 5:
230 goes into 2111 9 times with a remainder of 41.
The next digit of our result is 9. 
Result so far: 109.0
Subtracting 2070 from 2111 leaves us with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 230

On to step 6:
230 can be fit into 413 1 times, resulting in a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 1091.0
Subtracting 230 from 413 leaves us with 183.
Bring next digit (9) of the dividend behind the 183 and repeat the process: 1839 / 230

Moving on to step 7:
When dividing 1839 by 230, we get 7 with a remainder of 229.
Use 7 as the next digit of our solution. 
Result so far: 10917.0
Deduct 1610 from 1839 and we're left with 229.
Fetch the next digit (4) from the dividend, attach it to 229 and continue: 2294 / 230

Let's proceed to step 8:
If we divide 2294 by 230, we get 9 and a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 109179.0
If we take 2070 away from 2294, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 9:
230 goes into 2240 9 times with a remainder of 170.
Use 9 as the next digit of our solution. 
Result so far: 109179.9
Subtracting 2070 from 2240 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
1700 divided by 230 is 7 with a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 109179.97
Deduct 1610 from 1700 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
900 divided by 230 is 3 with a remainder of 210.
The next digit of our result is 3. 
Result so far: 109179.973
The remainder is 210 after subtracting 690 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
230 goes into 2100 9 times with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 109179.9739
The remainder is 30 after subtracting 2070 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
When dividing 300 by 230, we get 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 109179.97391
Deduct 230 from 300 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
700 divided by 230 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 109179.973913
Subtracting 690 from 700 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
When dividing 100 by 230, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 109179.973913
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
When dividing 1000 by 230, we get 4 with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 109179.97391304
Subtracting 920 from 1000 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.

The final outcome is 109179.97391304, with a leftover of 8e-08.
