408618 ÷ 19 
We want to figure out the number of times 408618 can be divided by 19.

Let's proceed to step 1:
4 divided by 19 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 19

Advancing to step 2:
40 divided by 19 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 2 after subtracting 38 from 40.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 19

Step 3:
The number 19 fits into 28 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 19 from 28, we get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 19

Going ahead to step 4:
If we divide 96 by 19, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 215.0
If we subtract 95 from 96, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 19

Moving on to step 5:
When dividing 11 by 19, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 2150.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 19

On to step 6:
The number 19 fits into 118 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 21506.0
If we subtract 114 from 118, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
19 goes into 40 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 21506.2
If we subtract 38 from 40, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 21506.21
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
19 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 21506.21
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 19, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21506.2105
If we take 95 away from 100, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
19 goes into 50 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 21506.21052
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
If we divide 120 by 19, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 21506.210526
If we take 114 away from 120, we end up 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.

Going ahead to step 13:
60 divided by 19 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 21506.2105263
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
19 goes into 30 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 21506.21052631
Subtract 19 from 30 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 21506.21052631, with a leftover of 1.1e-08.
