31536467 ÷ 800 
The aim is to understand the frequency of 800 in 31536467.

Moving on to step 1:
If we divide 3 by 800, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 800

Going ahead to step 2:
800 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 800

On to step 3:
800 can be fit into 315 0 times, resulting in a remainder of 315.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 315, we get 315.
Fetch the next digit (3) from the dividend, attach it to 315 and continue: 3153 / 800

Step 4:
3153 divided by 800 is 3 with a remainder of 753.
The next digit of our result is 3. 
Result so far: 3.0
If we take 2400 away from 3153, we end up with 753.
Grab the next digit (6) from the dividend, add it to 753, then carry on: 7536 / 800

Let's proceed to step 5:
800 goes into 7536 9 times with a remainder of 336.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 7200 from 7536 and we're left with 336.
Bring next digit (4) of the dividend behind the 336 and repeat the process: 3364 / 800

Step 6:
The number 800 fits into 3364 4 times, leaving a remainder of 164.
Put 4 as the next digit of the answer. 
Result so far: 394.0
Deduct 3200 from 3364 and we're left with 164.
Fetch the next digit (6) from the dividend, attach it to 164 and continue: 1646 / 800

Going ahead to step 7:
1646 divided by 800 is 2 with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 3942.0
If we subtract 1600 from 1646, we get 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 800

Going ahead to step 8:
When dividing 467 by 800, we get 0 with a remainder of 467.
Write down 0 as next digit of the result. 
Result so far: 39420.0
Subtract 0 from 467 to get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Step 9:
If we divide 4670 by 800, we get 5 and a remainder of 670.
Use 5 as the next digit of our solution. 
Result so far: 39420.5
Subtract 4000 from 4670 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 10:
When dividing 6700 by 800, we get 8 with a remainder of 300.
The number 8 becomes the next digit in our result. 
Result so far: 39420.58
Subtract 6400 from 6700 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:
3000 divided by 800 is 3 with a remainder of 600.
The number 3 becomes the next digit in our result. 
Result so far: 39420.583
The remainder is 600 after subtracting 2400 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 12:
800 goes into 6000 7 times with a remainder of 400.
Put 7 as the next digit of the answer. 
Result so far: 39420.5837
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.

Step 13:
When dividing 4000 by 800, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39420.58375
Deduct 4000 from 4000 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.

Let's proceed to step 14:
If we divide 0 by 800, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39420.58375
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.

Let's proceed to step 15:
The number 800 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 39420.58375
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 39420.58375 with a remainder of 0.0.
