87997823 divided by 315 
The aim is to understand the frequency of 315 in 87997823.

Advancing to step 1:
If we divide 8 by 315, we get 0 and 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.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 315

Let's proceed to step 2:
315 goes into 87 0 times with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 315

Advancing to step 3:
315 can be fit into 879 2 times, resulting in a remainder of 249.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 630 from 879, we get 249.
Append the next digit (9) from the dividend to 249 and continue with: 2499 / 315

Advancing to step 4:
315 can be fit into 2499 7 times, resulting in a remainder of 294.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 2205 from 2499 and we're left with 294.
Fetch the next digit (7) from the dividend, attach it to 294 and continue: 2947 / 315

Moving on to step 5:
2947 divided by 315 is 9 with a remainder of 112.
Use 9 as the next digit of our solution. 
Result so far: 279.0
If we subtract 2835 from 2947, we get 112.
Bring next digit (8) of the dividend behind the 112 and repeat the process: 1128 / 315

Advancing to step 6:
When dividing 1128 by 315, we get 3 with a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 2793.0
Deduct 945 from 1128 and we're left with 183.
Grab the next digit (2) from the dividend, add it to 183, then carry on: 1832 / 315

Let's proceed to step 7:
315 goes into 1832 5 times with a remainder of 257.
Record the quotient 5 as the next digit in the result. 
Result so far: 27935.0
If we take 1575 away from 1832, we end up with 257.
Fetch the next digit (3) from the dividend, attach it to 257 and continue: 2573 / 315

Step 8:
315 goes into 2573 8 times with a remainder of 53.
Record the quotient 8 as the next digit in the result. 
Result so far: 279358.0
Deduct 2520 from 2573 and we're left 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.

Moving on to step 9:
315 goes into 530 1 times with a remainder of 215.
Record the quotient 1 as the next digit in the result. 
Result so far: 279358.1
Subtracting 315 from 530 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 10:
The number 315 fits into 2150 6 times, leaving a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 279358.16
Deduct 1890 from 2150 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
If we divide 2600 by 315, we get 8 and a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 279358.168
Deduct 2520 from 2600 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
800 divided by 315 is 2 with a remainder of 170.
The next digit of our result is 2. 
Result so far: 279358.1682
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 13:
The number 315 fits into 1700 5 times, leaving a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 279358.16825
The remainder is 125 after subtracting 1575 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 14:
315 can be fit into 1250 3 times, resulting in a remainder of 305.
Record the quotient 3 as the next digit in the result. 
Result so far: 279358.168253
If we subtract 945 from 1250, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 15:
If we divide 3050 by 315, we get 9 and a remainder of 215.
Put 9 as the next digit of the answer. 
Result so far: 279358.1682539
If we subtract 2835 from 3050, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 16:
315 can be fit into 2150 6 times, resulting in a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 279358.16825396
If we subtract 1890 from 2150, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 279358.16825396 with a balance of 2.6e-07.
