17293003 ÷ 800 
The aim is to understand the frequency of 800 in 17293003.

Advancing to step 1:
When dividing 1 by 800, we get 0 with 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.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 800

Going ahead to step 2:
When dividing 17 by 800, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 800

Moving on to step 3:
The number 800 fits into 172 0 times, leaving a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 172 leaves us with 172.
Take the next digit (9) from the dividend and append it to 172, then repeat: 1729 / 800

Going ahead to step 4:
The number 800 fits into 1729 2 times, leaving a remainder of 129.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1600 from 1729, we get 129.
Include the next digit (3) from the dividend after 129, then repeat: 1293 / 800

Let's proceed to step 5:
If we divide 1293 by 800, we get 1 and a remainder of 493.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 800 from 1293 leaves us with 493.
Grab the next digit (0) from the dividend, add it to 493, then carry on: 4930 / 800

Moving on to step 6:
The number 800 fits into 4930 6 times, leaving a remainder of 130.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
If we subtract 4800 from 4930, we get 130.
Bring next digit (0) of the dividend behind the 130 and repeat the process: 1300 / 800

Moving on to step 7:
When dividing 1300 by 800, we get 1 with a remainder of 500.
The next digit of our result is 1. 
Result so far: 2161.0
If we take 800 away from 1300, we end up with 500.
Take the next digit (3) from the dividend and append it to 500, then repeat: 5003 / 800

Step 8:
800 can be fit into 5003 6 times, resulting in a remainder of 203.
The next digit of our result is 6. 
Result so far: 21616.0
Deduct 4800 from 5003 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 9:
800 goes into 2030 2 times with a remainder of 430.
Record the quotient 2 as the next digit in the result. 
Result so far: 21616.2
Subtract 1600 from 2030 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 10:
The number 800 fits into 4300 5 times, leaving a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 21616.25
Subtract 4000 from 4300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
800 goes into 3000 3 times with a remainder of 600.
Record the quotient 3 as the next digit in the result. 
Result so far: 21616.253
If we subtract 2400 from 3000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
6000 divided by 800 is 7 with a remainder of 400.
The number 7 becomes the next digit in our result. 
Result so far: 21616.2537
If we take 5600 away from 6000, we end up with 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:
When dividing 4000 by 800, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 21616.25375
Subtracting 4000 from 4000 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.

Let's proceed to step 14:
The number 800 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21616.25375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
800 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21616.25375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 21616.25375, and the remainder is 0.0.
