We divide 87013431 by 115
The aim is to understand the frequency of 115 in 87013431.

Moving on to step 1:
115 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 115

Moving on to step 2:
If we divide 87 by 115, we get 0 and a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 115

Let's proceed to step 3:
When dividing 870 by 115, we get 7 with a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 805 away from 870, we end up with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 115

On to step 4:
When dividing 651 by 115, we get 5 with a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
The remainder is 76 after subtracting 575 from 651.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 115

Step 5:
When dividing 763 by 115, we get 6 with a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 756.0
Subtract 690 from 763 to get 73.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 115

Advancing to step 6:
734 divided by 115 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 7566.0
Subtract 690 from 734 to get 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 115

Step 7:
443 divided by 115 is 3 with a remainder of 98.
Put 3 as the next digit of the answer. 
Result so far: 75663.0
If we subtract 345 from 443, we get 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 115

Moving on to step 8:
981 divided by 115 is 8 with a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 756638.0
If we subtract 920 from 981, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
The number 115 fits into 610 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 756638.5
Subtracting 575 from 610 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
350 divided by 115 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 756638.53
Deduct 345 from 350 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
115 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 756638.53
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 115 fits into 500 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 756638.5304
If we take 460 away from 500, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 115 is 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 756638.53043
If we subtract 345 from 400, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
When dividing 550 by 115, we get 4 with a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 756638.530434
If we subtract 460 from 550, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 15:
The number 115 fits into 900 7 times, leaving a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 756638.5304347
The remainder is 95 after subtracting 805 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 16:
950 divided by 115 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 756638.53043478
If we subtract 920 from 950, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 756638.53043478 and a remainder of 3e-08.
