839860 divided by 69 
Our goal is to divide 839860 by 69.

Advancing to step 1:
When dividing 8 by 69, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 69

Going ahead to step 2:
If we divide 83 by 69, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 69 from 83, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 69

Moving on to step 3:
The number 69 fits into 149 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 138 from 149 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 69

Step 4:
When dividing 118 by 69, we get 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtract 69 from 118 to get 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 69

Let's proceed to step 5:
The number 69 fits into 496 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1217.0
The remainder is 13 after subtracting 483 from 496.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 69

Advancing to step 6:
The number 69 fits into 130 1 times, leaving a remainder of 61.
The next digit of our result is 1. 
Result so far: 12171.0
Subtracting 69 from 130 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
The number 69 fits into 610 8 times, leaving a remainder of 58.
The next digit of our result is 8. 
Result so far: 12171.8
The remainder is 58 after subtracting 552 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
If we divide 580 by 69, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 12171.88
If we subtract 552 from 580, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 12171.88 with a remainder of 0.028.
