Let's divide 80505169 by 800
The aim is to understand the frequency of 800 in 80505169.

On to step 1:
If we divide 8 by 800, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 800

Let's proceed to step 2:
If we divide 80 by 800, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 800

On to step 3:
When dividing 805 by 800, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 5 after subtracting 800 from 805.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 800

Step 4:
50 divided by 800 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 50, we end up with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 800

Let's proceed to step 5:
800 can be fit into 505 0 times, resulting in a remainder of 505.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 505 leaves us with 505.
Append the next digit (1) from the dividend to 505 and continue with: 5051 / 800

Step 6:
When dividing 5051 by 800, we get 6 with a remainder of 251.
Put 6 as the next digit of the answer. 
Result so far: 1006.0
The remainder is 251 after subtracting 4800 from 5051.
Grab the next digit (6) from the dividend, add it to 251, then carry on: 2516 / 800

Moving on to step 7:
When dividing 2516 by 800, we get 3 with a remainder of 116.
The next digit of our result is 3. 
Result so far: 10063.0
If we take 2400 away from 2516, we end up with 116.
Grab the next digit (9) from the dividend, add it to 116, then carry on: 1169 / 800

Advancing to step 8:
800 can be fit into 1169 1 times, resulting in a remainder of 369.
The next digit of our result is 1. 
Result so far: 100631.0
Deduct 800 from 1169 and we're left with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
The number 800 fits into 3690 4 times, leaving a remainder of 490.
The next digit of our result is 4. 
Result so far: 100631.4
Subtract 3200 from 3690 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
If we divide 4900 by 800, we get 6 and a remainder of 100.
Put 6 as the next digit of the answer. 
Result so far: 100631.46
The remainder is 100 after subtracting 4800 from 4900.
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 11:
800 can be fit into 1000 1 times, resulting in a remainder of 200.
The next digit of our result is 1. 
Result so far: 100631.461
Subtracting 800 from 1000 leaves us 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.

Going ahead to step 12:
800 can be fit into 2000 2 times, resulting in a remainder of 400.
Use 2 as the next digit of our solution. 
Result so far: 100631.4612
If we take 1600 away from 2000, we end up 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.

Going ahead to step 13:
800 can be fit into 4000 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 100631.46125
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.

Let's proceed to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 100631.46125
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.

Let's proceed to step 15:
When dividing 0 by 800, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100631.46125
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.

The final outcome is 100631.46125, with a leftover of 0.0.
