We look at the division of 406312 by 19 
We want to figure out the number of times 406312 can be divided by 19.

Advancing to step 1:
If we divide 4 by 19, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 19

Step 2:
19 can be fit into 40 2 times, resulting in 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.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 19

Going ahead to step 3:
19 goes into 26 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 19 from 26 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 19

Let's proceed to step 4:
73 divided by 19 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
Deduct 57 from 73 and we're left with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 19

Step 5:
The number 19 fits into 161 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 2138.0
If we subtract 152 from 161, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 19

Step 6:
19 goes into 92 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 21384.0
If we take 76 away from 92, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
19 goes into 160 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 21384.8
The remainder is 8 after subtracting 152 from 160.
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 8:
19 goes into 80 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 21384.84
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
19 goes into 40 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 21384.842
Subtract 38 from 40 to 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 10:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21384.8421
If we take 19 away from 20, we end up 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.

Moving on to step 11:
If we divide 10 by 19, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 21384.8421
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
19 can be fit into 100 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 21384.842105
If we subtract 95 from 100, we get 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 13:
The number 19 fits into 50 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 21384.8421052
Deduct 38 from 50 and we're left with 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 14:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 21384.84210526
Deduct 114 from 120 and we're left 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.

The quotient of the division is 21384.84210526, and the remainder is 6e-09.
