We divide 87005687 by 872
The aim is to understand the frequency of 872 in 87005687.

On to step 1:
If we divide 8 by 872, we get 0 and a remainder of 8.
The next digit of our result is 0. 
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 / 872

Let's proceed to step 2:
When dividing 87 by 872, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 872

On to step 3:
When dividing 870 by 872, we get 0 with a remainder of 870.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 870 after subtracting 0 from 870.
Append the next digit (0) from the dividend to 870 and continue with: 8700 / 872

Step 4:
8700 divided by 872 is 9 with a remainder of 852.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7848 from 8700, we get 852.
Grab the next digit (5) from the dividend, add it to 852, then carry on: 8525 / 872

Advancing to step 5:
If we divide 8525 by 872, we get 9 and a remainder of 677.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 7848 from 8525 and we're left with 677.
Append the next digit (6) from the dividend to 677 and continue with: 6776 / 872

Step 6:
The number 872 fits into 6776 7 times, leaving a remainder of 672.
The number 7 becomes the next digit in our result. 
Result so far: 997.0
If we take 6104 away from 6776, we end up with 672.
Include the next digit (8) from the dividend after 672, then repeat: 6728 / 872

Step 7:
If we divide 6728 by 872, we get 7 and a remainder of 624.
Write down 7 as next digit of the result. 
Result so far: 9977.0
Subtract 6104 from 6728 to get 624.
Bring next digit (7) of the dividend behind the 624 and repeat the process: 6247 / 872

Moving on to step 8:
872 goes into 6247 7 times with a remainder of 143.
The next digit of our result is 7. 
Result so far: 99777.0
If we take 6104 away from 6247, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 9:
872 can be fit into 1430 1 times, resulting in a remainder of 558.
Use 1 as the next digit of our solution. 
Result so far: 99777.1
Deduct 872 from 1430 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 10:
5580 divided by 872 is 6 with a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 99777.16
Subtracting 5232 from 5580 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 11:
872 can be fit into 3480 3 times, resulting in a remainder of 864.
The number 3 becomes the next digit in our result. 
Result so far: 99777.163
Subtracting 2616 from 3480 leaves us with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Going ahead to step 12:
When dividing 8640 by 872, we get 9 with a remainder of 792.
Write down 9 as next digit of the result. 
Result so far: 99777.1639
If we take 7848 away from 8640, we end up with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Going ahead to step 13:
872 goes into 7920 9 times with a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 99777.16399
Subtract 7848 from 7920 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 99777.16399 with a balance of 7.2e-05.
