We divide 83514181 by 231
The aim is to understand the frequency of 231 in 83514181.

Step 1:
231 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 231

Going ahead to step 2:
When dividing 83 by 231, we get 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Bring next digit (5) of the dividend behind the 83 and repeat the process: 835 / 231

On to step 3:
The number 231 fits into 835 3 times, leaving a remainder of 142.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 142 after subtracting 693 from 835.
Bring next digit (1) of the dividend behind the 142 and repeat the process: 1421 / 231

Let's proceed to step 4:
If we divide 1421 by 231, we get 6 and a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 1386 from 1421 and we're left with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 231

Let's proceed to step 5:
The number 231 fits into 354 1 times, leaving a remainder of 123.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
Deduct 231 from 354 and we're left with 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 231

Let's proceed to step 6:
If we divide 1231 by 231, we get 5 and a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 3615.0
Deduct 1155 from 1231 and we're left with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 231

Moving on to step 7:
768 divided by 231 is 3 with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 36153.0
If we take 693 away from 768, we end up with 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 231

Advancing to step 8:
751 divided by 231 is 3 with a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 361533.0
The remainder is 58 after subtracting 693 from 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
If we divide 580 by 231, we get 2 and a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 361533.2
Subtract 462 from 580 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 10:
231 goes into 1180 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 361533.25
Deduct 1155 from 1180 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 231, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 361533.251
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
If we divide 190 by 231, we get 0 and a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 361533.251
The remainder is 190 after subtracting 0 from 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 13:
The number 231 fits into 1900 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 361533.25108
If we subtract 1848 from 1900, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
520 divided by 231 is 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 361533.251082
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
231 can be fit into 580 2 times, resulting in a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 361533.2510822
If we take 462 away from 580, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The final result is 361533.2510822 with a remainder of 1.18e-06.
