863359 ÷ 69 
We want to figure out the number of times 863359 can be divided by 69.

Moving on to step 1:
69 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 69

On to step 2:
When dividing 86 by 69, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 69 from 86.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 69

Let's proceed to step 3:
When dividing 173 by 69, we get 2 with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 138 from 173 leaves us with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 69

On to step 4:
69 can be fit into 353 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtracting 345 from 353 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 69

On to step 5:
69 can be fit into 85 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1251.0
Subtract 69 from 85 to get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 69

Let's proceed to step 6:
69 goes into 169 2 times with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 12512.0
Subtract 138 from 169 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.

Let's proceed to step 7:
The number 69 fits into 310 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 12512.4
Subtracting 276 from 310 leaves us 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.

Let's proceed to step 8:
If we divide 340 by 69, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 12512.44
The remainder is 64 after subtracting 276 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 12512.44 with a remaining 0.064.
