We look at the division of 38673965 by 231 
The aim is to understand the frequency of 231 in 38673965.

Step 1:
When dividing 3 by 231, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 231

Moving on to step 2:
38 divided by 231 is 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 231

Going ahead to step 3:
When dividing 386 by 231, we get 1 with a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 231 from 386 leaves us with 155.
Fetch the next digit (7) from the dividend, attach it to 155 and continue: 1557 / 231

Advancing to step 4:
If we divide 1557 by 231, we get 6 and a remainder of 171.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 1386 from 1557 to get 171.
Include the next digit (3) from the dividend after 171, then repeat: 1713 / 231

Let's proceed to step 5:
231 goes into 1713 7 times with a remainder of 96.
Write down 7 as next digit of the result. 
Result so far: 167.0
If we take 1617 away from 1713, we end up with 96.
Take the next digit (9) from the dividend and append it to 96, then repeat: 969 / 231

Let's proceed to step 6:
969 divided by 231 is 4 with a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 1674.0
If we subtract 924 from 969, we get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 231

Advancing to step 7:
If we divide 456 by 231, we get 1 and a remainder of 225.
Use 1 as the next digit of our solution. 
Result so far: 16741.0
Subtracting 231 from 456 leaves us with 225.
Fetch the next digit (5) from the dividend, attach it to 225 and continue: 2255 / 231

Advancing to step 8:
The number 231 fits into 2255 9 times, leaving a remainder of 176.
The next digit of our result is 9. 
Result so far: 167419.0
If we subtract 2079 from 2255, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 9:
231 goes into 1760 7 times with a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 167419.7
If we subtract 1617 from 1760, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 10:
The number 231 fits into 1430 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 167419.76
If we subtract 1386 from 1430, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
If we divide 440 by 231, we get 1 and a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 167419.761
The remainder is 209 after subtracting 231 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 12:
The number 231 fits into 2090 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 167419.7619
The remainder is 11 after subtracting 2079 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
When dividing 110 by 231, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 167419.7619
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 14:
231 can be fit into 1100 4 times, resulting in a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 167419.761904
Deduct 924 from 1100 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 15:
231 goes into 1760 7 times with a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 167419.7619047
Deduct 1617 from 1760 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 16:
231 can be fit into 1430 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 167419.76190476
Subtracting 1386 from 1430 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 167419.76190476, and the remainder is 4.4e-08.
