We look at the division of 44143487 by 231 
The aim is to understand the frequency of 231 in 44143487.

Let's proceed to step 1:
231 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 231

Let's proceed to step 2:
231 goes into 44 0 times with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 231

On to step 3:
441 divided by 231 is 1 with a remainder of 210.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 231 away from 441, we end up with 210.
Fetch the next digit (4) from the dividend, attach it to 210 and continue: 2104 / 231

On to step 4:
231 goes into 2104 9 times with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 2079 from 2104 and we're left with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 231

Moving on to step 5:
231 goes into 253 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 191.0
The remainder is 22 after subtracting 231 from 253.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 231

Let's proceed to step 6:
When dividing 224 by 231, we get 0 with a remainder of 224.
Write down 0 as next digit of the result. 
Result so far: 1910.0
The remainder is 224 after subtracting 0 from 224.
Take the next digit (8) from the dividend and append it to 224, then repeat: 2248 / 231

On to step 7:
The number 231 fits into 2248 9 times, leaving a remainder of 169.
The number 9 becomes the next digit in our result. 
Result so far: 19109.0
Subtract 2079 from 2248 to get 169.
Append the next digit (7) from the dividend to 169 and continue with: 1697 / 231

On to step 8:
When dividing 1697 by 231, we get 7 with a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 191097.0
The remainder is 80 after subtracting 1617 from 1697.
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:
231 goes into 800 3 times with a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 191097.3
Deduct 693 from 800 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 10:
When dividing 1070 by 231, we get 4 with a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 191097.34
If we subtract 924 from 1070, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 11:
1460 divided by 231 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 191097.346
Subtract 1386 from 1460 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
If we divide 740 by 231, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 191097.3463
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
The number 231 fits into 470 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 191097.34632
Subtracting 462 from 470 leaves us 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.

Going ahead to step 14:
When dividing 80 by 231, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 191097.34632
Subtract 0 from 80 to 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.

Advancing to step 15:
The number 231 fits into 800 3 times, leaving a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 191097.3463203
If we subtract 693 from 800, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 16:
When dividing 1070 by 231, we get 4 with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 191097.34632034
Subtracting 924 from 1070 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Our division results in 191097.34632034 with a remaining 1.46e-07.
