We look at the division of 3345530 by 800 
The aim is to understand the frequency of 800 in 3345530.

On to step 1:
The number 800 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 800

Step 2:
If we divide 33 by 800, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 800

Moving on to step 3:
When dividing 334 by 800, we get 0 with a remainder of 334.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 334 leaves us with 334.
Take the next digit (5) from the dividend and append it to 334, then repeat: 3345 / 800

Advancing to step 4:
If we divide 3345 by 800, we get 4 and a remainder of 145.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3200 away from 3345, we end up with 145.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 800

Going ahead to step 5:
800 goes into 1455 1 times with a remainder of 655.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtracting 800 from 1455 leaves us with 655.
Fetch the next digit (3) from the dividend, attach it to 655 and continue: 6553 / 800

Moving on to step 6:
When dividing 6553 by 800, we get 8 with a remainder of 153.
Record the quotient 8 as the next digit in the result. 
Result so far: 418.0
Deduct 6400 from 6553 and we're left with 153.
Include the next digit (0) from the dividend after 153, then repeat: 1530 / 800

Let's proceed to step 7:
800 can be fit into 1530 1 times, resulting in a remainder of 730.
Write down 1 as next digit of the result. 
Result so far: 4181.0
Deduct 800 from 1530 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Advancing to step 8:
800 goes into 7300 9 times with a remainder of 100.
Use 9 as the next digit of our solution. 
Result so far: 4181.9
Subtracting 7200 from 7300 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
The number 800 fits into 1000 1 times, leaving a remainder of 200.
The next digit of our result is 1. 
Result so far: 4181.91
Deduct 800 from 1000 and we're left 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.

Step 10:
If we divide 2000 by 800, we get 2 and a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 4181.912
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.

Going ahead to step 11:
If we divide 4000 by 800, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4181.9125
Subtract 4000 from 4000 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.

On to step 12:
When dividing 0 by 800, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4181.9125
If we take 0 away from 0, 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.

Advancing to step 13:
800 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4181.9125
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.

The final result is 4181.9125 with a remainder of 0.0.
