Let's divide 3578225 by 80
The aim is to understand the frequency of 80 in 3578225.

Moving on to step 1:
3 divided by 80 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 80

On to step 2:
When dividing 35 by 80, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 80

Step 3:
The number 80 fits into 357 4 times, leaving a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 320 from 357, we get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 80

On to step 4:
378 divided by 80 is 4 with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 320 from 378 and we're left with 58.
Take the next digit (2) from the dividend and append it to 58, then repeat: 582 / 80

Moving on to step 5:
80 goes into 582 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 447.0
Subtracting 560 from 582 leaves us with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 80

Moving on to step 6:
222 divided by 80 is 2 with a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 4472.0
The remainder is 62 after subtracting 160 from 222.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 80

Let's proceed to step 7:
625 divided by 80 is 7 with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 44727.0
Deduct 560 from 625 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
When dividing 650 by 80, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 44727.8
If we subtract 640 from 650, we get 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 9:
100 divided by 80 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 44727.81
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 44727.812
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.

Moving on to step 11:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 44727.8125
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.

Going ahead to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 44727.8125
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.

Going ahead to step 13:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 44727.8125
The remainder is 0 after subtracting 0 from 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 44727.8125, and the remainder is 0.0.
