Let's divide 83601 by 80
The aim is to understand the frequency of 80 in 83601.

Moving on to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 80

Moving on to step 2:
80 goes into 83 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 80 from 83.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 80

Let's proceed to step 3:
When dividing 36 by 80, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 36, we end up with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 80

Step 4:
The number 80 fits into 360 4 times, leaving a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we take 320 away from 360, we end up with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 80

On to step 5:
When dividing 401 by 80, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 1045.0
The remainder is 1 after subtracting 400 from 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
When dividing 10 by 80, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1045.0
If we take 0 away from 10, 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.

Let's proceed to step 7:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1045.01
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 1045.012
Subtracting 160 from 200 leaves us 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.

Going ahead to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1045.0125
If we take 400 away from 400, 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 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1045.0125
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.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1045.0125
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 quotient of the division is 1045.0125, and the remainder is 0.0.
