We're dividing 816506 by 42 
We want to figure out the number of times 816506 can be divided by 42.

Step 1:
42 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 42

Moving on to step 2:
81 divided by 42 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
If we take 42 away from 81, we end up with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 42

Let's proceed to step 3:
42 can be fit into 396 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 378 from 396, we get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 42

On to step 4:
42 goes into 185 4 times with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 194.0
If we take 168 away from 185, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 42

On to step 5:
When dividing 170 by 42, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1944.0
If we subtract 168 from 170, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 42

On to step 6:
The number 42 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 19440.0
Subtract 0 from 26 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
If we divide 260 by 42, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 19440.6
Subtracting 252 from 260 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.

Moving on to step 8:
80 divided by 42 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 19440.61
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
When dividing 380 by 42, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19440.619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19440.619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 19440.61904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 19440.619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
42 goes into 260 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 19440.6190476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
80 divided by 42 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 19440.61904761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 19440.61904761, and the remainder is 3.8e-08.
