We look at the division of 420535 by 19 
Our goal is to divide 420535 by 19.

Step 1:
4 divided by 19 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 19

Moving on to step 2:
19 goes into 42 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 38 away from 42, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 19

On to step 3:
The number 19 fits into 40 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 2 after subtracting 38 from 40.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 19

Moving on to step 4:
19 can be fit into 25 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
Deduct 19 from 25 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 19

Advancing to step 5:
The number 19 fits into 63 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 2213.0
Subtracting 57 from 63 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 19

Going ahead to step 6:
65 divided by 19 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 22133.0
Subtracting 57 from 65 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
19 goes into 80 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 22133.4
Subtracting 76 from 80 leaves us 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.

Advancing to step 8:
When dividing 40 by 19, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22133.42
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 9:
If we divide 20 by 19, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 22133.421
Subtracting 19 from 20 leaves us 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.

On to step 10:
When dividing 10 by 19, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 22133.421
Subtracting 0 from 10 leaves us 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.

Step 11:
100 divided by 19 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 22133.42105
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.

On to step 12:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 22133.421052
The remainder is 12 after subtracting 38 from 50.
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 13:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 22133.4210526
If we subtract 114 from 120, we get 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 14:
60 divided by 19 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 22133.42105263
If we take 57 away from 60, we end up 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.

The quotient of the division is 22133.42105263, and the remainder is 3e-09.
