Let's divide 876800 by 87
The aim is to understand the frequency of 87 in 876800.

Advancing to step 1:
The number 87 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 87

Advancing to step 2:
When dividing 87 by 87, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 87 from 87, we get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 87

Going ahead to step 3:
87 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 87

Let's proceed to step 4:
The number 87 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 68 after subtracting 0 from 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 87

Step 5:
The number 87 fits into 680 7 times, leaving a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 1007.0
The remainder is 71 after subtracting 609 from 680.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 87

Let's proceed to step 6:
When dividing 710 by 87, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 10078.0
Subtracting 696 from 710 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
The number 87 fits into 140 1 times, leaving a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 10078.1
Subtract 87 from 140 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 8:
87 can be fit into 530 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10078.16
Deduct 522 from 530 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
87 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 10078.16
If we take 0 away from 80, we end up 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.

Advancing to step 10:
800 divided by 87 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 10078.1609
Deduct 783 from 800 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
170 divided by 87 is 1 with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 10078.16091
If we take 87 away from 170, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 12:
If we divide 830 by 87, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 10078.160919
If we subtract 783 from 830, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
470 divided by 87 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 10078.1609195
Subtracting 435 from 470 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.

Moving on to step 14:
87 goes into 350 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 10078.16091954
Subtract 348 from 350 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 10078.16091954, and the remainder is 2e-09.
