Let's divide 974451 by 80
The aim is to understand the frequency of 80 in 974451.

Moving on to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 80

Let's proceed to step 2:
80 goes into 97 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 97 and we're left with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 80

Going ahead to step 3:
If we divide 174 by 80, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 160 from 174 to get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 80

Advancing to step 4:
If we divide 144 by 80, we get 1 and a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we take 80 away from 144, we end up with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 80

Advancing to step 5:
80 goes into 645 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 1218.0
If we subtract 640 from 645, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 80

Going ahead to step 6:
51 divided by 80 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 12180.0
If we subtract 0 from 51, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
If we divide 510 by 80, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 12180.6
If we subtract 480 from 510, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 80 is 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 12180.63
Subtracting 240 from 300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
80 goes into 600 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 12180.637
Subtracting 560 from 600 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 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12180.6375
Subtract 400 from 400 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.

Let's proceed to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12180.6375
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 12180.6375
If we subtract 0 from 0, we 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.

The quotient of the division is 12180.6375, and the remainder is 0.0.
