We look at the division of 91982104 by 788 
The aim is to understand the frequency of 788 in 91982104.

Going ahead to step 1:
When dividing 9 by 788, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 788

Step 2:
788 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Fetch the next digit (9) from the dividend, attach it to 91 and continue: 919 / 788

Let's proceed to step 3:
788 goes into 919 1 times with a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 131 after subtracting 788 from 919.
Append the next digit (8) from the dividend to 131 and continue with: 1318 / 788

Let's proceed to step 4:
If we divide 1318 by 788, we get 1 and a remainder of 530.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 530 after subtracting 788 from 1318.
Take the next digit (2) from the dividend and append it to 530, then repeat: 5302 / 788

Moving on to step 5:
When dividing 5302 by 788, we get 6 with a remainder of 574.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 4728 from 5302 to get 574.
Take the next digit (1) from the dividend and append it to 574, then repeat: 5741 / 788

On to step 6:
If we divide 5741 by 788, we get 7 and a remainder of 225.
The next digit of our result is 7. 
Result so far: 1167.0
Deduct 5516 from 5741 and we're left with 225.
Bring next digit (0) of the dividend behind the 225 and repeat the process: 2250 / 788

Let's proceed to step 7:
2250 divided by 788 is 2 with a remainder of 674.
The number 2 becomes the next digit in our result. 
Result so far: 11672.0
Subtracting 1576 from 2250 leaves us with 674.
Bring next digit (4) of the dividend behind the 674 and repeat the process: 6744 / 788

Step 8:
788 goes into 6744 8 times with a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 116728.0
Subtract 6304 from 6744 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 9:
788 can be fit into 4400 5 times, resulting in a remainder of 460.
The next digit of our result is 5. 
Result so far: 116728.5
If we subtract 3940 from 4400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 10:
4600 divided by 788 is 5 with a remainder of 660.
Use 5 as the next digit of our solution. 
Result so far: 116728.55
Subtracting 3940 from 4600 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

After the division, we end up with 116728.55 and a remainder of 0.66.
