We divide 40459445 by 80
The aim is to understand the frequency of 80 in 40459445.

On to step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 80

Going ahead to step 2:
When dividing 40 by 80, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 80

Advancing to step 3:
80 can be fit into 404 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 400 from 404 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 80

Step 4:
If we divide 45 by 80, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 80

Advancing to step 5:
80 can be fit into 459 5 times, resulting in a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
If we subtract 400 from 459, we get 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 80

Moving on to step 6:
The number 80 fits into 594 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 5057.0
If we subtract 560 from 594, we get 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 80

Moving on to step 7:
The number 80 fits into 344 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 50574.0
Subtract 320 from 344 to get 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 80

Going ahead to step 8:
80 goes into 245 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 505743.0
Subtract 240 from 245 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 80, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 505743.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 80 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 505743.06
If we subtract 480 from 500, 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.

Let's proceed to step 11:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 505743.062
The remainder is 40 after subtracting 160 from 200.
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 12:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 505743.0625
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.

Step 13:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 505743.0625
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.

Advancing to step 14:
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: 505743.0625
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 quotient of the division is 505743.0625, and the remainder is 0.0.
