We look at the division of 802531 by 19 
We want to figure out the number of times 802531 can be divided by 19.

On to step 1:
19 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 19

On to step 2:
19 goes into 80 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 76 from 80, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 19

Step 3:
When dividing 42 by 19, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 38 from 42 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 19

Going ahead to step 4:
When dividing 45 by 19, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
If we subtract 38 from 45, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 19

Step 5:
If we divide 73 by 19, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 4223.0
Deduct 57 from 73 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 19

On to step 6:
If we divide 161 by 19, we get 8 and a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 42238.0
The remainder is 9 after subtracting 152 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 42238.4
Subtracting 76 from 90 leaves us 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 8:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 42238.47
Subtract 133 from 140 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 42238.473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
19 goes into 130 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 42238.4736
If we take 114 away from 130, 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.

On to step 11:
19 goes into 160 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 42238.47368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
19 goes into 80 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 42238.473684
Subtract 76 from 80 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
40 divided by 19 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 42238.4736842
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.

Advancing to step 14:
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: 42238.47368421
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.

The final result is 42238.47368421 with a remainder of 1e-09.
