We divide 15153000 by 800
The aim is to understand the frequency of 800 in 15153000.

Step 1:
1 divided by 800 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 800

Moving on to step 2:
If we divide 15 by 800, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 800

Let's proceed to step 3:
When dividing 151 by 800, we get 0 with a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Include the next digit (5) from the dividend after 151, then repeat: 1515 / 800

Moving on to step 4:
1515 divided by 800 is 1 with a remainder of 715.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 800 from 1515 to get 715.
Take the next digit (3) from the dividend and append it to 715, then repeat: 7153 / 800

Moving on to step 5:
When dividing 7153 by 800, we get 8 with a remainder of 753.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 6400 from 7153 and we're left with 753.
Fetch the next digit (0) from the dividend, attach it to 753 and continue: 7530 / 800

Step 6:
If we divide 7530 by 800, we get 9 and a remainder of 330.
Use 9 as the next digit of our solution. 
Result so far: 189.0
Subtract 7200 from 7530 to get 330.
Include the next digit (0) from the dividend after 330, then repeat: 3300 / 800

On to step 7:
If we divide 3300 by 800, we get 4 and a remainder of 100.
The next digit of our result is 4. 
Result so far: 1894.0
Subtract 3200 from 3300 to get 100.
Bring next digit (0) of the dividend behind the 100 and repeat the process: 1000 / 800

Going ahead to step 8:
800 can be fit into 1000 1 times, resulting in a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 18941.0
Subtract 800 from 1000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 9:
If we divide 2000 by 800, we get 2 and a remainder of 400.
Use 2 as the next digit of our solution. 
Result so far: 18941.2
If we subtract 1600 from 2000, we 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.

Step 10:
4000 divided by 800 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 18941.25
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.

Moving on to step 11:
If we divide 0 by 800, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18941.25
Subtract 0 from 0 to 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.

Step 12:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18941.25
Subtract 0 from 0 to 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.

The final result is 18941.25 with a remainder of 0.0.
