88870 ÷ 80 
The aim is to understand the frequency of 80 in 88870.

On to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 80

Moving on to step 2:
The number 80 fits into 88 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 80 from 88 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 80

Advancing to step 3:
If we divide 88 by 80, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 80 away from 88, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 80

Step 4:
80 can be fit into 87 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we take 80 away from 87, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 80

Advancing to step 5:
80 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 1110.0
If we take 0 away from 70, we end up with 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 6:
700 divided by 80 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 1110.8
Subtracting 640 from 700 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.

Step 7:
When dividing 600 by 80, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 1110.87
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.

Going ahead to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1110.875
If we take 400 away from 400, 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 9:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1110.875
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.

Let's proceed to step 10:
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: 1110.875
Subtracting 0 from 0 leaves us 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 1110.875, with a leftover of 0.0.
