19404242 ÷ 117 
Our goal is to divide 19404242 by 117.

Advancing to step 1:
The number 117 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 117

Let's proceed to step 2:
117 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 117

On to step 3:
194 divided by 117 is 1 with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 77 after subtracting 117 from 194.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 117

Advancing to step 4:
The number 117 fits into 770 6 times, leaving a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 702 away from 770, we end up with 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 117

Advancing to step 5:
117 goes into 684 5 times with a remainder of 99.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we subtract 585 from 684, we get 99.
Take the next digit (2) from the dividend and append it to 99, then repeat: 992 / 117

On to step 6:
992 divided by 117 is 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 1658.0
Deduct 936 from 992 and we're left with 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 117

On to step 7:
564 divided by 117 is 4 with a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 16584.0
The remainder is 96 after subtracting 468 from 564.
Fetch the next digit (2) from the dividend, attach it to 96 and continue: 962 / 117

Step 8:
The number 117 fits into 962 8 times, leaving a remainder of 26.
The next digit of our result is 8. 
Result so far: 165848.0
Subtract 936 from 962 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
117 goes into 260 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 165848.2
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 117 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 165848.22
Deduct 234 from 260 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 165848.22 with a remainder of 0.026.
