42434010 ÷ 800 
The aim is to understand the frequency of 800 in 42434010.

Advancing to step 1:
When dividing 4 by 800, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 800

Let's proceed to step 2:
The number 800 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 800

Let's proceed to step 3:
800 goes into 424 0 times with a remainder of 424.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 424, we end up with 424.
Fetch the next digit (3) from the dividend, attach it to 424 and continue: 4243 / 800

Going ahead to step 4:
The number 800 fits into 4243 5 times, leaving a remainder of 243.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4000 away from 4243, we end up with 243.
Take the next digit (4) from the dividend and append it to 243, then repeat: 2434 / 800

Going ahead to step 5:
If we divide 2434 by 800, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtracting 2400 from 2434 leaves us with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 800

Advancing to step 6:
When dividing 340 by 800, we get 0 with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 530.0
If we subtract 0 from 340, we get 340.
Take the next digit (1) from the dividend and append it to 340, then repeat: 3401 / 800

Going ahead to step 7:
800 goes into 3401 4 times with a remainder of 201.
The number 4 becomes the next digit in our result. 
Result so far: 5304.0
Subtract 3200 from 3401 to get 201.
Bring next digit (0) of the dividend behind the 201 and repeat the process: 2010 / 800

On to step 8:
The number 800 fits into 2010 2 times, leaving a remainder of 410.
Write down 2 as next digit of the result. 
Result so far: 53042.0
Subtracting 1600 from 2010 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 9:
If we divide 4100 by 800, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 53042.5
Subtract 4000 from 4100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
When dividing 1000 by 800, we get 1 with a remainder of 200.
The number 1 becomes the next digit in our result. 
Result so far: 53042.51
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.

Step 11:
If we divide 2000 by 800, we get 2 and a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 53042.512
Deduct 1600 from 2000 and we're left 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.

Step 12:
When dividing 4000 by 800, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 53042.5125
The remainder is 0 after subtracting 4000 from 4000.
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 13:
800 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 53042.5125
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.

Advancing to step 14:
0 divided by 800 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 53042.5125
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.

After the division, we end up with 53042.5125 and a remainder of 0.0.
