We divide 763809 by 87
The aim is to understand the frequency of 87 in 763809.

Advancing to step 1:
87 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 87

Step 2:
If we divide 76 by 87, we get 0 and a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 87

Moving on to step 3:
87 goes into 763 8 times with a remainder of 67.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 696 from 763 to get 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 87

Going ahead to step 4:
87 can be fit into 678 7 times, resulting in a remainder of 69.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 609 from 678 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 87

Let's proceed to step 5:
When dividing 690 by 87, we get 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 877.0
Deduct 609 from 690 and we're left with 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 87

Advancing to step 6:
If we divide 819 by 87, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 8779.0
If we subtract 783 from 819, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
360 divided by 87 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 8779.4
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
When dividing 120 by 87, we get 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 8779.41
Deduct 87 from 120 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
When dividing 330 by 87, we get 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 8779.413
Subtract 261 from 330 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
87 can be fit into 690 7 times, resulting in a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 8779.4137
The remainder is 81 after subtracting 609 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 11:
The number 87 fits into 810 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 8779.41379
If we subtract 783 from 810, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 8779.413793
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
90 divided by 87 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 8779.4137931
Subtracting 87 from 90 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
87 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8779.4137931
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 8779.4137931 and a remainder of 3e-08.
