Let's divide 78101180 by 787
The aim is to understand the frequency of 787 in 78101180.

Going ahead to step 1:
787 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 787

On to step 2:
787 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 787

On to step 3:
781 divided by 787 is 0 with a remainder of 781.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 781 and we're left with 781.
Include the next digit (0) from the dividend after 781, then repeat: 7810 / 787

Let's proceed to step 4:
7810 divided by 787 is 9 with a remainder of 727.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7083 away from 7810, we end up with 727.
Append the next digit (1) from the dividend to 727 and continue with: 7271 / 787

Moving on to step 5:
787 can be fit into 7271 9 times, resulting in a remainder of 188.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 7083 from 7271 to get 188.
Take the next digit (1) from the dividend and append it to 188, then repeat: 1881 / 787

On to step 6:
If we divide 1881 by 787, we get 2 and a remainder of 307.
The number 2 becomes the next digit in our result. 
Result so far: 992.0
If we take 1574 away from 1881, we end up with 307.
Fetch the next digit (8) from the dividend, attach it to 307 and continue: 3078 / 787

On to step 7:
787 goes into 3078 3 times with a remainder of 717.
The number 3 becomes the next digit in our result. 
Result so far: 9923.0
Subtracting 2361 from 3078 leaves us with 717.
Append the next digit (0) from the dividend to 717 and continue with: 7170 / 787

On to step 8:
If we divide 7170 by 787, we get 9 and a remainder of 87.
Write down 9 as next digit of the result. 
Result so far: 99239.0
Deduct 7083 from 7170 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 9:
If we divide 870 by 787, we get 1 and a remainder of 83.
The next digit of our result is 1. 
Result so far: 99239.1
Deduct 787 from 870 and we're left 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.

Going ahead to step 10:
The number 787 fits into 830 1 times, leaving a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 99239.11
If we take 787 away from 830, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 99239.11, and the remainder is 0.043.
