881272 ÷ 7 
The aim is to understand the frequency of 7 in 881272.

Step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 7 from 8, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 7

On to step 2:
7 goes into 18 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 14 from 18, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 7

Moving on to step 3:
7 can be fit into 41 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtracting 35 from 41 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 7

Step 4:
If we divide 62 by 7, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 1258.0
Subtract 56 from 62 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 7

Moving on to step 5:
7 goes into 67 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 12589.0
If we take 63 away from 67, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 7

Step 6:
42 divided by 7 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 125896.0
If we subtract 42 from 42, 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.

Let's proceed to step 7:
0 divided by 7 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 125896.0
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.

Step 8:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 125896.0
Subtract 0 from 0 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.

The final outcome is 125896.0, with a leftover of 0.0.
