863842 ÷ 69 
The aim is to understand the frequency of 69 in 863842.

Step 1:
If we divide 8 by 69, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 69

On to step 2:
The number 69 fits into 86 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 69 from 86 leaves us with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 69

Moving on to step 3:
173 divided by 69 is 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 12.0
If we take 138 away from 173, we end up with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 69

Step 4:
When dividing 358 by 69, we get 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 13 after subtracting 345 from 358.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 69

On to step 5:
When dividing 134 by 69, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1251.0
If we take 69 away from 134, we end up with 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 69

Moving on to step 6:
If we divide 652 by 69, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 12519.0
Subtract 621 from 652 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
69 can be fit into 310 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 12519.4
If we take 276 away from 310, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
The number 69 fits into 340 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 12519.44
Subtracting 276 from 340 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 12519.44 with a balance of 0.064.
