839646 ÷ 69 
Our goal is to divide 839646 by 69.

Moving on to step 1:
When dividing 8 by 69, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 69

On to step 2:
69 can be fit into 83 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 14 after subtracting 69 from 83.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 69

Step 3:
149 divided by 69 is 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 11 after subtracting 138 from 149.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 69

Advancing to step 4:
When dividing 116 by 69, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtracting 69 from 116 leaves us with 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 69

Advancing to step 5:
69 goes into 474 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 1216.0
The remainder is 60 after subtracting 414 from 474.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 69

On to step 6:
When dividing 606 by 69, we get 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 12168.0
Subtracting 552 from 606 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
69 can be fit into 540 7 times, resulting in a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 12168.7
Subtracting 483 from 540 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 8:
69 goes into 570 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 12168.78
Deduct 552 from 570 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 69, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 12168.782
Deduct 138 from 180 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 69, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 12168.7826
If we take 414 away from 420, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
69 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 12168.7826
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
69 goes into 600 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 12168.782608
Deduct 552 from 600 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
69 goes into 480 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 12168.7826086
Deduct 414 from 480 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
69 can be fit into 660 9 times, resulting in a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 12168.78260869
Subtracting 621 from 660 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 12168.78260869, with a leftover of 3.9e-08.
