15940106 ÷ 18 
Let's see how many times 18 fits into 15940106.

On to step 1:
18 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 18

Moving on to step 2:
When dividing 15 by 18, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 18

Step 3:
159 divided by 18 is 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 15 after subtracting 144 from 159.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 18

Let's proceed to step 4:
18 can be fit into 154 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Deduct 144 from 154 and we're left with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 18

Let's proceed to step 5:
100 divided by 18 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 885.0
Subtracting 90 from 100 leaves us with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 18

Moving on to step 6:
The number 18 fits into 101 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 8855.0
If we subtract 90 from 101, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 18

Step 7:
18 goes into 110 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 88556.0
Subtract 108 from 110 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 18

Advancing to step 8:
The number 18 fits into 26 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 885561.0
Subtracting 18 from 26 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.

Moving on to step 9:
80 divided by 18 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 885561.4
If we take 72 away from 80, we end up 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.

On to step 10:
The number 18 fits into 80 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 885561.44
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.

The final outcome is 885561.44, with a leftover of 0.008.
