961666 ÷ 86 
Our goal is to divide 961666 by 86.

Going ahead to step 1:
86 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 86

Going ahead to step 2:
86 goes into 96 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 86 from 96 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 86

Let's proceed to step 3:
The number 86 fits into 101 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 86 from 101 leaves us with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 86

Advancing to step 4:
The number 86 fits into 156 1 times, leaving a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we subtract 86 from 156, we get 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 86

Moving on to step 5:
When dividing 706 by 86, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 1118.0
If we subtract 688 from 706, we get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 86

Moving on to step 6:
186 divided by 86 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 11182.0
Subtract 172 from 186 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
When dividing 140 by 86, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 11182.1
If we take 86 away from 140, we end up 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 8:
86 can be fit into 540 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 11182.16
Subtracting 516 from 540 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
240 divided by 86 is 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 11182.162
The remainder is 68 after subtracting 172 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
86 goes into 680 7 times with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 11182.1627
Subtract 602 from 680 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
When dividing 780 by 86, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 11182.16279
Subtracting 774 from 780 leaves us 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.

Step 12:
The number 86 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11182.16279
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
86 goes into 600 6 times with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 11182.1627906
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 11182.16279069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 11182.16279069 and a remainder of 6.6e-08.
