827458 ÷ 876 
The aim is to understand the frequency of 876 in 827458.

On to step 1:
When dividing 8 by 876, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 876

Advancing to step 2:
82 divided by 876 is 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Take the next digit (7) from the dividend and append it to 82, then repeat: 827 / 876

Let's proceed to step 3:
The number 876 fits into 827 0 times, leaving a remainder of 827.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 827 after subtracting 0 from 827.
Append the next digit (4) from the dividend to 827 and continue with: 8274 / 876

On to step 4:
876 can be fit into 8274 9 times, resulting in a remainder of 390.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7884 from 8274 and we're left with 390.
Append the next digit (5) from the dividend to 390 and continue with: 3905 / 876

Step 5:
The number 876 fits into 3905 4 times, leaving a remainder of 401.
Put 4 as the next digit of the answer. 
Result so far: 94.0
The remainder is 401 after subtracting 3504 from 3905.
Bring next digit (8) of the dividend behind the 401 and repeat the process: 4018 / 876

On to step 6:
876 goes into 4018 4 times with a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 944.0
Subtract 3504 from 4018 to get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

On to step 7:
876 goes into 5140 5 times with a remainder of 760.
The number 5 becomes the next digit in our result. 
Result so far: 944.5
If we subtract 4380 from 5140, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 8:
876 can be fit into 7600 8 times, resulting in a remainder of 592.
Put 8 as the next digit of the answer. 
Result so far: 944.58
Subtract 7008 from 7600 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 9:
If we divide 5920 by 876, we get 6 and a remainder of 664.
The next digit of our result is 6. 
Result so far: 944.586
Subtracting 5256 from 5920 leaves us with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 10:
6640 divided by 876 is 7 with a remainder of 508.
Write down 7 as next digit of the result. 
Result so far: 944.5867
Deduct 6132 from 6640 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 11:
When dividing 5080 by 876, we get 5 with a remainder of 700.
The next digit of our result is 5. 
Result so far: 944.58675
Subtracting 4380 from 5080 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 12:
If we divide 7000 by 876, we get 7 and a remainder of 868.
Put 7 as the next digit of the answer. 
Result so far: 944.586757
If we subtract 6132 from 7000, we get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Step 13:
876 goes into 8680 9 times with a remainder of 796.
Write down 9 as next digit of the result. 
Result so far: 944.5867579
If we subtract 7884 from 8680, we get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

On to step 14:
876 can be fit into 7960 9 times, resulting in a remainder of 76.
The next digit of our result is 9. 
Result so far: 944.58675799
Subtracting 7884 from 7960 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 944.58675799 and a remainder of 7.6e-08.
