We look at the division of 16503899 by 788 
The aim is to understand the frequency of 788 in 16503899.

Let's proceed to step 1:
The number 788 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 788

Step 2:
788 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 788

Let's proceed to step 3:
165 divided by 788 is 0 with a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 165, we get 165.
Fetch the next digit (0) from the dividend, attach it to 165 and continue: 1650 / 788

On to step 4:
If we divide 1650 by 788, we get 2 and a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 74 after subtracting 1576 from 1650.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 788

Moving on to step 5:
The number 788 fits into 743 0 times, leaving a remainder of 743.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 743 and we're left with 743.
Grab the next digit (8) from the dividend, add it to 743, then carry on: 7438 / 788

Moving on to step 6:
The number 788 fits into 7438 9 times, leaving a remainder of 346.
Use 9 as the next digit of our solution. 
Result so far: 209.0
Subtracting 7092 from 7438 leaves us with 346.
Fetch the next digit (9) from the dividend, attach it to 346 and continue: 3469 / 788

Advancing to step 7:
788 goes into 3469 4 times with a remainder of 317.
Record the quotient 4 as the next digit in the result. 
Result so far: 2094.0
If we take 3152 away from 3469, we end up with 317.
Bring next digit (9) of the dividend behind the 317 and repeat the process: 3179 / 788

Step 8:
When dividing 3179 by 788, we get 4 with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 20944.0
If we subtract 3152 from 3179, 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.

On to step 9:
788 can be fit into 270 0 times, resulting in a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 20944.0
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
788 can be fit into 2700 3 times, resulting in a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 20944.03
Subtract 2364 from 2700 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 11:
If we divide 3360 by 788, we get 4 and a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 20944.034
If we subtract 3152 from 3360, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
When dividing 2080 by 788, we get 2 with a remainder of 504.
Use 2 as the next digit of our solution. 
Result so far: 20944.0342
If we take 1576 away from 2080, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 13:
5040 divided by 788 is 6 with a remainder of 312.
Write down 6 as next digit of the result. 
Result so far: 20944.03426
If we take 4728 away from 5040, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 14:
788 goes into 3120 3 times with a remainder of 756.
The next digit of our result is 3. 
Result so far: 20944.034263
The remainder is 756 after subtracting 2364 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Moving on to step 15:
788 goes into 7560 9 times with a remainder of 468.
Write down 9 as next digit of the result. 
Result so far: 20944.0342639
Subtracting 7092 from 7560 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 16:
788 can be fit into 4680 5 times, resulting in a remainder of 740.
Use 5 as the next digit of our solution. 
Result so far: 20944.03426395
Subtracting 3940 from 4680 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The final result is 20944.03426395 with a remainder of 7.4e-07.
