We divide 728159 by 87
The aim is to understand the frequency of 87 in 728159.

Step 1:
87 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 87

Moving on to step 2:
87 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 87

Let's proceed to step 3:
When dividing 728 by 87, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 32 after subtracting 696 from 728.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 87

On to step 4:
If we divide 321 by 87, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 261 away from 321, we end up with 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 87

Step 5:
605 divided by 87 is 6 with a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 836.0
Subtract 522 from 605 to get 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 87

Step 6:
87 goes into 839 9 times with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 8369.0
Subtracting 783 from 839 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
If we divide 560 by 87, we get 6 and a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 8369.6
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
87 can be fit into 380 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 8369.64
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
87 can be fit into 320 3 times, resulting in a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 8369.643
Subtracting 261 from 320 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
When dividing 590 by 87, we get 6 with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 8369.6436
If we subtract 522 from 590, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
When dividing 680 by 87, we get 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 8369.64367
Deduct 609 from 680 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
If we divide 710 by 87, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 8369.643678
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 13:
87 goes into 140 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 8369.6436781
If we take 87 away from 140, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
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: 8369.64367816
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.

The quotient of the division is 8369.64367816, and the remainder is 8e-09.
