Let's divide 428840 by 19
We want to figure out the number of times 428840 can be divided by 19.

Let's proceed to step 1:
19 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 19

Moving on to step 2:
19 can be fit into 42 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 38 away from 42, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 19

Going ahead to step 3:
19 can be fit into 48 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 38 from 48, we get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 19

Let's proceed to step 4:
If we divide 108 by 19, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 225.0
The remainder is 13 after subtracting 95 from 108.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 19

Moving on to step 5:
The number 19 fits into 134 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2257.0
Subtract 133 from 134 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 19

Advancing to step 6:
10 divided by 19 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 22570.0
Subtract 0 from 10 to 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.

Moving on to step 7:
When dividing 100 by 19, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 22570.5
Subtract 95 from 100 to 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.

Advancing to step 8:
When dividing 50 by 19, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 22570.52
Subtract 38 from 50 to 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.

On to step 9:
19 goes into 120 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 22570.526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
19 goes into 60 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 22570.5263
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.

Moving on to step 11:
19 goes into 30 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 22570.52631
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.

Step 12:
When dividing 110 by 19, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22570.526315
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.

Advancing to step 13:
If we divide 150 by 19, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 22570.5263157
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 14:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 22570.52631578
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.

After the division, we end up with 22570.52631578 and a remainder of 1.8e-08.
