We're dividing 907966 by 86 
We want to divide 907966 by 86.

Going ahead to step 1:
The number 86 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 86

Moving on to step 2:
If we divide 90 by 86, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 90 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 86

Going ahead to step 3:
If we divide 47 by 86, we get 0 and a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 47, we get 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 86

Going ahead to step 4:
86 can be fit into 479 5 times, resulting in a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 430 from 479 leaves us with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 86

Advancing to step 5:
When dividing 496 by 86, we get 5 with a remainder of 66.
The next digit of our result is 5. 
Result so far: 1055.0
The remainder is 66 after subtracting 430 from 496.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 86

Step 6:
If we divide 666 by 86, we get 7 and a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 10557.0
If we subtract 602 from 666, 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 7:
86 goes into 640 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 10557.7
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 10557.74
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 86 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10557.744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 10557.744 and a remainder of 0.0016.
