We're dividing 89836005 by 231 
The aim is to understand the frequency of 231 in 89836005.

On to step 1:
When dividing 8 by 231, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 231

Going ahead to step 2:
89 divided by 231 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 231

Moving on to step 3:
The number 231 fits into 898 3 times, leaving a remainder of 205.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 693 from 898 to get 205.
Take the next digit (3) from the dividend and append it to 205, then repeat: 2053 / 231

Step 4:
2053 divided by 231 is 8 with a remainder of 205.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Deduct 1848 from 2053 and we're left with 205.
Grab the next digit (6) from the dividend, add it to 205, then carry on: 2056 / 231

Step 5:
2056 divided by 231 is 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 388.0
If we subtract 1848 from 2056, we get 208.
Bring next digit (0) of the dividend behind the 208 and repeat the process: 2080 / 231

Let's proceed to step 6:
The number 231 fits into 2080 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3889.0
Subtracting 2079 from 2080 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 231

Step 7:
10 divided by 231 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 38890.0
Subtract 0 from 10 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 231

On to step 8:
If we divide 105 by 231, we get 0 and a remainder of 105.
Use 0 as the next digit of our solution. 
Result so far: 388900.0
Subtract 0 from 105 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 9:
When dividing 1050 by 231, we get 4 with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 388900.4
Subtract 924 from 1050 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 10:
231 can be fit into 1260 5 times, resulting in a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 388900.45
Subtract 1155 from 1260 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 11:
1050 divided by 231 is 4 with a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 388900.454
If we subtract 924 from 1050, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 12:
When dividing 1260 by 231, we get 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 388900.4545
Subtract 1155 from 1260 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
The number 231 fits into 1050 4 times, leaving a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 388900.45454
If we subtract 924 from 1050, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 14:
When dividing 1260 by 231, we get 5 with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 388900.454545
Subtracting 1155 from 1260 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 15:
231 goes into 1050 4 times with a remainder of 126.
The next digit of our result is 4. 
Result so far: 388900.4545454
If we take 924 away from 1050, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 16:
231 goes into 1260 5 times with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 388900.45454545
The remainder is 105 after subtracting 1155 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 388900.45454545 with a remaining 1.05e-07.
