The aim is to understand the frequency of 876 in 72637904.

Advancing to step 1:
876 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 876

Moving on to step 2:
The number 876 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 876

Advancing to step 3:
The number 876 fits into 726 0 times, leaving a remainder of 726.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 726 after subtracting 0 from 726.
Grab the next digit (3) from the dividend, add it to 726, then carry on: 7263 / 876

Step 4:
7263 divided by 876 is 8 with a remainder of 255.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7008 from 7263 and we're left with 255.
Bring next digit (7) of the dividend behind the 255 and repeat the process: 2557 / 876

Moving on to step 5:
876 can be fit into 2557 2 times, resulting in a remainder of 805.
The next digit of our result is 2. 
Result so far: 82.0
Subtract 1752 from 2557 to get 805.
Grab the next digit (9) from the dividend, add it to 805, then carry on: 8059 / 876

Going ahead to step 6:
876 can be fit into 8059 9 times, resulting in a remainder of 175.
Put 9 as the next digit of the answer. 
Result so far: 829.0
The remainder is 175 after subtracting 7884 from 8059.
Grab the next digit (0) from the dividend, add it to 175, then carry on: 1750 / 876

Let's proceed to step 7:
If we divide 1750 by 876, we get 1 and a remainder of 874.
The number 1 becomes the next digit in our result. 
Result so far: 8291.0
If we subtract 876 from 1750, we get 874.
Bring next digit (4) of the dividend behind the 874 and repeat the process: 8744 / 876

Moving on to step 8:
876 goes into 8744 9 times with a remainder of 860.
The next digit of our result is 9. 
Result so far: 82919.0
Subtract 7884 from 8744 to get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Going ahead to step 9:
When dividing 8600 by 876, we get 9 with a remainder of 716.
Put 9 as the next digit of the answer. 
Result so far: 82919.9
Subtract 7884 from 8600 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 10:
876 can be fit into 7160 8 times, resulting in a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 82919.98
Deduct 7008 from 7160 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
The number 876 fits into 1520 1 times, leaving a remainder of 644.
Use 1 as the next digit of our solution. 
Result so far: 82919.981
If we subtract 876 from 1520, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 12:
If we divide 6440 by 876, we get 7 and a remainder of 308.
Write down 7 as next digit of the result. 
Result so far: 82919.9817
The remainder is 308 after subtracting 6132 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 13:
3080 divided by 876 is 3 with a remainder of 452.
The next digit of our result is 3. 
Result so far: 82919.98173
Deduct 2628 from 3080 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 14:
When dividing 4520 by 876, we get 5 with a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 82919.981735
Subtract 4380 from 4520 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 15:
The number 876 fits into 1400 1 times, leaving a remainder of 524.
Use 1 as the next digit of our solution. 
Result so far: 82919.9817351
Deduct 876 from 1400 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 16:
5240 divided by 876 is 5 with a remainder of 860.
Put 5 as the next digit of the answer. 
Result so far: 82919.98173515
If we subtract 4380 from 5240, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

In conclusion, the division gives 82919.98173515 with a balance of 8.6e-07.
