31894640 ÷ 230 
The aim is to understand the frequency of 230 in 31894640.

On to step 1:
230 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 230

Moving on to step 2:
When dividing 31 by 230, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 230

On to step 3:
The number 230 fits into 318 1 times, leaving a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 230 from 318 and we're left with 88.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 230

Let's proceed to step 4:
889 divided by 230 is 3 with a remainder of 199.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 199 after subtracting 690 from 889.
Grab the next digit (4) from the dividend, add it to 199, then carry on: 1994 / 230

On to step 5:
If we divide 1994 by 230, we get 8 and a remainder of 154.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we take 1840 away from 1994, we end up with 154.
Include the next digit (6) from the dividend after 154, then repeat: 1546 / 230

On to step 6:
1546 divided by 230 is 6 with a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 1386.0
Subtracting 1380 from 1546 leaves us with 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 230

Moving on to step 7:
1664 divided by 230 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 13867.0
Subtracting 1610 from 1664 leaves us with 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 230

Step 8:
230 goes into 540 2 times with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 138672.0
If we subtract 460 from 540, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
230 goes into 800 3 times with a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 138672.3
Subtracting 690 from 800 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
230 can be fit into 1100 4 times, resulting in a remainder of 180.
Write down 4 as next digit of the result. 
Result so far: 138672.34
Subtracting 920 from 1100 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
230 goes into 1800 7 times with a remainder of 190.
Record the quotient 7 as the next digit in the result. 
Result so far: 138672.347
Subtract 1610 from 1800 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 12:
The number 230 fits into 1900 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 138672.3478
The remainder is 60 after subtracting 1840 from 1900.
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 13:
230 can be fit into 600 2 times, resulting in a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 138672.34782
Subtract 460 from 600 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
If we divide 1400 by 230, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 138672.347826
Subtract 1380 from 1400 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
200 divided by 230 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 138672.347826
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
230 can be fit into 2000 8 times, resulting in a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 138672.34782608
If we subtract 1840 from 2000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 138672.34782608 and a remainder of 1.6e-07.
