We divide 17670919 by 80
The aim is to understand the frequency of 80 in 17670919.

Moving on to step 1:
80 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 80

Let's proceed to step 2:
80 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 80

Advancing to step 3:
80 can be fit into 176 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 160 away from 176, we end up with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 80

On to step 4:
80 goes into 167 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 160 away from 167, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 80

Step 5:
70 divided by 80 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 220.0
Subtract 0 from 70 to get 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 80

On to step 6:
If we divide 709 by 80, we get 8 and a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 2208.0
If we take 640 away from 709, we end up with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 80

Let's proceed to step 7:
The number 80 fits into 691 8 times, leaving a remainder of 51.
The next digit of our result is 8. 
Result so far: 22088.0
If we subtract 640 from 691, we get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 80

Moving on to step 8:
When dividing 519 by 80, we get 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 220886.0
If we subtract 480 from 519, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
80 goes into 390 4 times with a remainder of 70.
The next digit of our result is 4. 
Result so far: 220886.4
If we subtract 320 from 390, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
If we divide 700 by 80, we get 8 and a remainder of 60.
The next digit of our result is 8. 
Result so far: 220886.48
Deduct 640 from 700 and we're left 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.

Advancing to step 11:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The next digit of our result is 7. 
Result so far: 220886.487
Subtract 560 from 600 to get 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 12:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 220886.4875
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.

Going ahead to step 13:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 220886.4875
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 14:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 220886.4875
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 220886.4875, with a leftover of 0.0.
