Let's divide 101861 by 18
We want to divide 101861 by 18.

On to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 18

Going ahead to step 2:
If we divide 10 by 18, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 18

Step 3:
If we divide 101 by 18, we get 5 and a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 11 after subtracting 90 from 101.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 18

On to step 4:
18 goes into 118 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 108 from 118 to get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 18

Advancing to step 5:
The number 18 fits into 106 5 times, leaving a remainder of 16.
The next digit of our result is 5. 
Result so far: 565.0
Subtract 90 from 106 to get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 18

Moving on to step 6:
When dividing 161 by 18, we get 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 5658.0
If we subtract 144 from 161, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 18 fits into 170 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 5658.9
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 18, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 5658.94
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 18 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 5658.944
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 5658.944 and a remainder of 0.0008.
