We divide 877187 by 69
The aim is to understand the frequency of 69 in 877187.

On to step 1:
69 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 69

Step 2:
69 goes into 87 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 18 after subtracting 69 from 87.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 69

Let's proceed to step 3:
If we divide 187 by 69, we get 2 and a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 138 from 187 leaves us with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 69

Step 4:
The number 69 fits into 491 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Subtract 483 from 491 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 69

Moving on to step 5:
88 divided by 69 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1271.0
Deduct 69 from 88 and we're left with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 69

Step 6:
69 can be fit into 197 2 times, resulting in a remainder of 59.
The next digit of our result is 2. 
Result so far: 12712.0
Subtracting 138 from 197 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
When dividing 590 by 69, we get 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 12712.8
If we subtract 552 from 590, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
380 divided by 69 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12712.85
Subtracting 345 from 380 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 69 fits into 350 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12712.855
The remainder is 5 after subtracting 345 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 12712.855, with a leftover of 0.0005.
