966449 ÷ 86 
We're looking to find how many times 86 goes into 966449.

Advancing to step 1:
9 divided by 86 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 86

Moving on to step 2:
The number 86 fits into 96 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 86 from 96 and we're left with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 86

On to step 3:
The number 86 fits into 106 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 86 from 106 leaves us with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 86

Going ahead to step 4:
86 goes into 204 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 172 away from 204, we end up with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 86

Moving on to step 5:
86 goes into 324 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 1123.0
If we subtract 258 from 324, we get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 86

Advancing to step 6:
When dividing 669 by 86, we get 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 11237.0
The remainder is 67 after subtracting 602 from 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
86 can be fit into 670 7 times, resulting in a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 11237.7
If we subtract 602 from 670, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
86 can be fit into 680 7 times, resulting in a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 11237.77
If we take 602 away from 680, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 11237.77 with a remainder of 0.078.
