We're dividing 87950003 by 231 
The aim is to understand the frequency of 231 in 87950003.

Let's proceed to step 1:
8 divided by 231 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 231

On to step 2:
When dividing 87 by 231, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 231

Let's proceed to step 3:
When dividing 879 by 231, we get 3 with a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 693 from 879 and we're left with 186.
Take the next digit (5) from the dividend and append it to 186, then repeat: 1865 / 231

Moving on to step 4:
231 can be fit into 1865 8 times, resulting in a remainder of 17.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 1848 from 1865 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 231

Step 5:
When dividing 170 by 231, we get 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 380.0
The remainder is 170 after subtracting 0 from 170.
Grab the next digit (0) from the dividend, add it to 170, then carry on: 1700 / 231

Advancing to step 6:
If we divide 1700 by 231, we get 7 and a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 3807.0
Subtracting 1617 from 1700 leaves us with 83.
Bring next digit (0) of the dividend behind the 83 and repeat the process: 830 / 231

On to step 7:
231 can be fit into 830 3 times, resulting in a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 38073.0
If we take 693 away from 830, we end up with 137.
Include the next digit (3) from the dividend after 137, then repeat: 1373 / 231

Moving on to step 8:
The number 231 fits into 1373 5 times, leaving a remainder of 218.
Use 5 as the next digit of our solution. 
Result so far: 380735.0
Subtract 1155 from 1373 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 9:
The number 231 fits into 2180 9 times, leaving a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 380735.9
If we take 2079 away from 2180, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 10:
231 goes into 1010 4 times with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 380735.94
Subtract 924 from 1010 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 11:
The number 231 fits into 860 3 times, leaving a remainder of 167.
Use 3 as the next digit of our solution. 
Result so far: 380735.943
Subtract 693 from 860 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 12:
231 can be fit into 1670 7 times, resulting in a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 380735.9437
Subtracting 1617 from 1670 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
The number 231 fits into 530 2 times, leaving a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 380735.94372
Deduct 462 from 530 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
When dividing 680 by 231, we get 2 with a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 380735.943722
The remainder is 218 after subtracting 462 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 380735.943722, with a leftover of 2.18e-05.
