835783 ÷ 80 
The aim is to understand the frequency of 80 in 835783.

Moving on to step 1:
80 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 80

Moving on to step 2:
83 divided by 80 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 83 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 80

Step 3:
80 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 80

Step 4:
The number 80 fits into 357 4 times, leaving a remainder of 37.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 320 from 357, we get 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 80

Advancing to step 5:
378 divided by 80 is 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 1044.0
Subtract 320 from 378 to get 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 80

Advancing to step 6:
If we divide 583 by 80, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 10447.0
Deduct 560 from 583 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 80, we get 2 with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 10447.2
Deduct 160 from 230 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 10447.28
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 10447.287
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10447.2875
Deduct 400 from 400 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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10447.2875
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.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10447.2875
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.

The final outcome is 10447.2875, with a leftover of 0.0.
