Let's divide 775109 by 87
The aim is to understand the frequency of 87 in 775109.

On to step 1:
If we divide 7 by 87, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 87

Moving on to step 2:
The number 87 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 87

Let's proceed to step 3:
775 divided by 87 is 8 with a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 79 after subtracting 696 from 775.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 87

On to step 4:
87 goes into 791 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we take 783 away from 791, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 87

Let's proceed to step 5:
80 divided by 87 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 890.0
If we subtract 0 from 80, we get 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 87

Moving on to step 6:
If we divide 809 by 87, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 8909.0
The remainder is 26 after subtracting 783 from 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
When dividing 260 by 87, we get 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 8909.2
Subtracting 174 from 260 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 8:
860 divided by 87 is 9 with a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 8909.29
If we subtract 783 from 860, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
770 divided by 87 is 8 with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 8909.298
Deduct 696 from 770 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
87 goes into 740 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 8909.2988
If we take 696 away from 740, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 8909.2988, with a leftover of 0.00044.
