Let's divide 23165957 by 878
The aim is to understand the frequency of 878 in 23165957.

Going ahead to step 1:
2 divided by 878 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 878

Let's proceed to step 2:
878 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 878

Advancing to step 3:
231 divided by 878 is 0 with a remainder of 231.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 231 leaves us with 231.
Take the next digit (6) from the dividend and append it to 231, then repeat: 2316 / 878

On to step 4:
2316 divided by 878 is 2 with a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1756 from 2316, we get 560.
Fetch the next digit (5) from the dividend, attach it to 560 and continue: 5605 / 878

Let's proceed to step 5:
878 can be fit into 5605 6 times, resulting in a remainder of 337.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 5268 from 5605 to get 337.
Include the next digit (9) from the dividend after 337, then repeat: 3379 / 878

On to step 6:
If we divide 3379 by 878, we get 3 and a remainder of 745.
The next digit of our result is 3. 
Result so far: 263.0
Subtract 2634 from 3379 to get 745.
Append the next digit (5) from the dividend to 745 and continue with: 7455 / 878

On to step 7:
878 can be fit into 7455 8 times, resulting in a remainder of 431.
The next digit of our result is 8. 
Result so far: 2638.0
Subtracting 7024 from 7455 leaves us with 431.
Append the next digit (7) from the dividend to 431 and continue with: 4317 / 878

Moving on to step 8:
If we divide 4317 by 878, we get 4 and a remainder of 805.
The next digit of our result is 4. 
Result so far: 26384.0
Subtracting 3512 from 4317 leaves us with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

On to step 9:
When dividing 8050 by 878, we get 9 with a remainder of 148.
Put 9 as the next digit of the answer. 
Result so far: 26384.9
Deduct 7902 from 8050 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 10:
878 can be fit into 1480 1 times, resulting in a remainder of 602.
The number 1 becomes the next digit in our result. 
Result so far: 26384.91
If we subtract 878 from 1480, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 11:
The number 878 fits into 6020 6 times, leaving a remainder of 752.
Record the quotient 6 as the next digit in the result. 
Result so far: 26384.916
Subtract 5268 from 6020 to get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Let's proceed to step 12:
878 goes into 7520 8 times with a remainder of 496.
Put 8 as the next digit of the answer. 
Result so far: 26384.9168
Subtracting 7024 from 7520 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 13:
878 goes into 4960 5 times with a remainder of 570.
Write down 5 as next digit of the result. 
Result so far: 26384.91685
Subtracting 4390 from 4960 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 14:
878 can be fit into 5700 6 times, resulting in a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 26384.916856
Deduct 5268 from 5700 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 15:
The number 878 fits into 4320 4 times, leaving a remainder of 808.
Put 4 as the next digit of the answer. 
Result so far: 26384.9168564
The remainder is 808 after subtracting 3512 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Going ahead to step 16:
When dividing 8080 by 878, we get 9 with a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 26384.91685649
Subtracting 7902 from 8080 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final outcome is 26384.91685649, with a leftover of 1.78e-07.
