We divide 703545 by 80
The aim is to understand the frequency of 80 in 703545.

Moving on to step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 80

Let's proceed to step 2:
When dividing 70 by 80, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 80

On to step 3:
80 can be fit into 703 8 times, resulting in a remainder of 63.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 640 from 703, we get 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 80

On to step 4:
The number 80 fits into 635 7 times, leaving a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtract 560 from 635 to get 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 80

Step 5:
80 goes into 754 9 times with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 879.0
Subtracting 720 from 754 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 80

Advancing to step 6:
If we divide 345 by 80, we get 4 and a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 8794.0
If we subtract 320 from 345, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
The number 80 fits into 250 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 8794.3
If we take 240 away from 250, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 80 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 8794.31
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 8794.312
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8794.3125
Subtract 400 from 400 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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8794.3125
Subtract 0 from 0 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.

Going ahead to step 12:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8794.3125
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 result is 8794.3125 with a remainder of 0.0.
