We look at the division of 609456 by 86 
We're looking to find how many times 86 goes into 609456.

Going ahead to step 1:
6 divided by 86 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 86

Advancing to step 2:
If we divide 60 by 86, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 86

Moving on to step 3:
86 can be fit into 609 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
If we take 602 away from 609, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 86

Advancing to step 4:
If we divide 74 by 86, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 74 leaves us with 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 86

On to step 5:
When dividing 745 by 86, we get 8 with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 708.0
If we take 688 away from 745, we end up with 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 86

Step 6:
86 goes into 576 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 7086.0
Subtract 516 from 576 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.

Step 7:
600 divided by 86 is 6 with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 7086.6
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 8:
When dividing 840 by 86, we get 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 7086.69
Subtracting 774 from 840 leaves us 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.

Going ahead to step 9:
86 goes into 660 7 times with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7086.697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
580 divided by 86 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7086.6976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 7086.69767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7086.697674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
360 divided by 86 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7086.6976744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 7086.6976744, with a leftover of 1.6e-07.
