We look at the division of 408943 by 19 
We want to divide 408943 by 19.

Going ahead to step 1:
The number 19 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our 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

Going ahead to step 2:
If we divide 40 by 19, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 2 after subtracting 38 from 40.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 19

Going ahead to step 3:
When dividing 28 by 19, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 19 from 28 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 19

Step 4:
When dividing 99 by 19, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 215.0
Subtracting 95 from 99 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 19

Advancing to step 5:
If we divide 44 by 19, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2152.0
Deduct 38 from 44 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 19

On to step 6:
19 can be fit into 63 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 21523.0
Deduct 57 from 63 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.

Going ahead to step 7:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 21523.3
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 21523.31
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
When dividing 110 by 19, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 21523.315
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 21523.3157
Subtract 133 from 150 to 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.

Going ahead to step 11:
170 divided by 19 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 21523.31578
Deduct 152 from 170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
19 goes into 180 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 21523.315789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
90 divided by 19 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 21523.3157894
Deduct 76 from 90 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
140 divided by 19 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 21523.31578947
Deduct 133 from 140 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 21523.31578947, with a leftover of 7e-09.
