17497949 ÷ 800 
The aim is to understand the frequency of 800 in 17497949.

Let's proceed to step 1:
If we divide 1 by 800, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 800

Going ahead to step 2:
The number 800 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 800

On to step 3:
The number 800 fits into 174 0 times, leaving a remainder of 174.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 174 and we're left with 174.
Take the next digit (9) from the dividend and append it to 174, then repeat: 1749 / 800

Let's proceed to step 4:
If we divide 1749 by 800, we get 2 and a remainder of 149.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1600 from 1749, we get 149.
Bring next digit (7) of the dividend behind the 149 and repeat the process: 1497 / 800

On to step 5:
The number 800 fits into 1497 1 times, leaving a remainder of 697.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 800 from 1497 and we're left with 697.
Grab the next digit (9) from the dividend, add it to 697, then carry on: 6979 / 800

On to step 6:
6979 divided by 800 is 8 with a remainder of 579.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
The remainder is 579 after subtracting 6400 from 6979.
Take the next digit (4) from the dividend and append it to 579, then repeat: 5794 / 800

Moving on to step 7:
If we divide 5794 by 800, we get 7 and a remainder of 194.
The number 7 becomes the next digit in our result. 
Result so far: 2187.0
Subtract 5600 from 5794 to get 194.
Grab the next digit (9) from the dividend, add it to 194, then carry on: 1949 / 800

Let's proceed to step 8:
The number 800 fits into 1949 2 times, leaving a remainder of 349.
Put 2 as the next digit of the answer. 
Result so far: 21872.0
Subtracting 1600 from 1949 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 9:
When dividing 3490 by 800, we get 4 with a remainder of 290.
Use 4 as the next digit of our solution. 
Result so far: 21872.4
The remainder is 290 after subtracting 3200 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
800 goes into 2900 3 times with a remainder of 500.
Record the quotient 3 as the next digit in the result. 
Result so far: 21872.43
Subtract 2400 from 2900 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
The number 800 fits into 5000 6 times, leaving a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 21872.436
Subtracting 4800 from 5000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
When dividing 2000 by 800, we get 2 with a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 21872.4362
Subtract 1600 from 2000 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
4000 divided by 800 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 21872.43625
If we take 4000 away from 4000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 21872.43625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
0 divided by 800 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21872.43625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 21872.43625 with a balance of 0.0.
