186663 ÷ 86 
We're looking to find how many times 86 goes into 186663.

Advancing to step 1:
1 divided by 86 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 86

On to step 2:
86 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 86

Moving on to step 3:
If we divide 186 by 86, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 172 from 186 to get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 86

On to step 4:
If we divide 146 by 86, we get 1 and a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 86 from 146, we get 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 86

Going ahead to step 5:
86 goes into 606 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Deduct 602 from 606 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 86

On to step 6:
86 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 2170.0
Deduct 0 from 43 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
86 can be fit into 430 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 2170.5
The remainder is 0 after subtracting 430 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
86 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2170.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
86 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2170.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2170.5 with a remainder of 0.0.
