Let's divide 84970287 by 800
The aim is to understand the frequency of 800 in 84970287.

Step 1:
800 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 800

Step 2:
800 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Take the next digit (9) from the dividend and append it to 84, then repeat: 849 / 800

Going ahead to step 3:
800 can be fit into 849 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 49 after subtracting 800 from 849.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 800

Step 4:
800 goes into 497 0 times with a remainder of 497.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 497 leaves us with 497.
Include the next digit (0) from the dividend after 497, then repeat: 4970 / 800

Step 5:
800 goes into 4970 6 times with a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 4800 from 4970 and we're left with 170.
Take the next digit (2) from the dividend and append it to 170, then repeat: 1702 / 800

Step 6:
The number 800 fits into 1702 2 times, leaving a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 1062.0
The remainder is 102 after subtracting 1600 from 1702.
Fetch the next digit (8) from the dividend, attach it to 102 and continue: 1028 / 800

Going ahead to step 7:
When dividing 1028 by 800, we get 1 with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 10621.0
If we subtract 800 from 1028, we get 228.
Bring next digit (7) of the dividend behind the 228 and repeat the process: 2287 / 800

Step 8:
The number 800 fits into 2287 2 times, leaving a remainder of 687.
Put 2 as the next digit of the answer. 
Result so far: 106212.0
If we take 1600 away from 2287, we end up with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Advancing to step 9:
800 goes into 6870 8 times with a remainder of 470.
Write down 8 as next digit of the result. 
Result so far: 106212.8
Deduct 6400 from 6870 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 10:
800 can be fit into 4700 5 times, resulting in a remainder of 700.
Record the quotient 5 as the next digit in the result. 
Result so far: 106212.85
The remainder is 700 after subtracting 4000 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 11:
800 can be fit into 7000 8 times, resulting in a remainder of 600.
Record the quotient 8 as the next digit in the result. 
Result so far: 106212.858
The remainder is 600 after subtracting 6400 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
800 can be fit into 6000 7 times, resulting in a remainder of 400.
Put 7 as the next digit of the answer. 
Result so far: 106212.8587
Subtract 5600 from 6000 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.

Going ahead to step 13:
When dividing 4000 by 800, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 106212.85875
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.

On 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: 106212.85875
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.

On to step 15:
800 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 106212.85875
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 final result is 106212.85875 with a remainder of 0.0.
