402792 ÷ 19 
Let's see how many times 19 fits into 402792.

Step 1:
If we divide 4 by 19, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 19

Moving on to step 2:
19 can be fit into 40 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 38 away from 40, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 19

Advancing to step 3:
22 divided by 19 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 19 from 22, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 19

On to step 4:
19 can be fit into 37 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
Subtract 19 from 37 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 19

Moving on to step 5:
19 goes into 189 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 2119.0
Deduct 171 from 189 and we're left with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 19

Going ahead to step 6:
The number 19 fits into 182 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 21199.0
If we take 171 away from 182, we end up 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 7:
If we divide 110 by 19, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 21199.5
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
19 can be fit into 150 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 21199.57
If we subtract 133 from 150, we 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.

Advancing to step 9:
When dividing 170 by 19, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 21199.578
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.

Going ahead to step 10:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 21199.5789
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
90 divided by 19 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 21199.57894
Subtract 76 from 90 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
19 goes into 140 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 21199.578947
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.

Going ahead to step 13:
If we divide 70 by 19, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 21199.5789473
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
19 goes into 130 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 21199.57894736
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 21199.57894736, with a leftover of 1.6e-08.
