876623 ÷ 80 
The aim is to understand the frequency of 80 in 876623.

Going ahead 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
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 80

Step 2:
The number 80 fits into 87 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 80 from 87 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 80

Let's proceed to step 3:
76 divided by 80 is 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 76, we get 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 80

Going ahead to step 4:
80 can be fit into 766 9 times, resulting in a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 720 from 766, we get 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 80

Advancing to step 5:
If we divide 462 by 80, we get 5 and a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
If we subtract 400 from 462, we get 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 80

Going ahead to step 6:
80 goes into 623 7 times with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 10957.0
Subtracting 560 from 623 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
If we divide 630 by 80, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 10957.7
If we subtract 560 from 630, 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.

Step 8:
700 divided by 80 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 10957.78
The remainder is 60 after subtracting 640 from 700.
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:
If we divide 600 by 80, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 10957.787
If we take 560 away from 600, we end up 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 10:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10957.7875
If we subtract 400 from 400, 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.

On to step 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10957.7875
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 12:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10957.7875
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.

Our division results in 10957.7875 with a remaining 0.0.
