Let's divide 819637 by 42
Our goal is to divide 819637 by 42.

Let's proceed to step 1:
42 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 42

Moving on to step 2:
81 divided by 42 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 81 leaves us with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 42

Let's proceed to step 3:
The number 42 fits into 399 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 378 away from 399, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 42

Step 4:
If we divide 216 by 42, we get 5 and a remainder of 6.
The next digit of our result is 5. 
Result so far: 195.0
The remainder is 6 after subtracting 210 from 216.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 42

Let's proceed to step 5:
63 divided by 42 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1951.0
Subtract 42 from 63 to get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 42

Let's proceed to step 6:
The number 42 fits into 217 5 times, leaving a remainder of 7.
The next digit of our result is 5. 
Result so far: 19515.0
Deduct 210 from 217 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.

Moving on to step 7:
If we divide 70 by 42, we get 1 and a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 19515.1
Deduct 42 from 70 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
If we divide 280 by 42, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 19515.16
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
42 can be fit into 280 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 19515.166
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 19515.166, and the remainder is 0.0028.
