83023692 ÷ 80 
The aim is to understand the frequency of 80 in 83023692.

Advancing to step 1:
8 divided by 80 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 80

Moving on to step 2:
83 divided by 80 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 80 from 83 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 80

Advancing to step 3:
The number 80 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 80

Step 4:
The number 80 fits into 302 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 103.0
The remainder is 62 after subtracting 240 from 302.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 80

Let's proceed to step 5:
When dividing 623 by 80, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 1037.0
If we subtract 560 from 623, we get 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 80

On to step 6:
636 divided by 80 is 7 with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 10377.0
Subtract 560 from 636 to get 76.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 80

On to step 7:
The number 80 fits into 769 9 times, leaving a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 103779.0
Deduct 720 from 769 and we're left with 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 80

Advancing to step 8:
492 divided by 80 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1037796.0
The remainder is 12 after subtracting 480 from 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 80 fits into 120 1 times, leaving a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1037796.1
If we take 80 away from 120, we end up 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.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1037796.15
The remainder is 0 after subtracting 400 from 400.
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:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1037796.15
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.

On to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1037796.15
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 1037796.15, with a leftover of 0.0.
