812871 divided by 42 
Let's see how many times 42 fits into 812871.

On to step 1:
8 divided by 42 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 42

On to step 2:
42 goes into 81 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 42 away from 81, we end up with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 42

Let's proceed to step 3:
392 divided by 42 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 378 from 392 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 42

Advancing to step 4:
The number 42 fits into 148 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 193.0
Deduct 126 from 148 and we're left with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 42

Let's proceed to step 5:
227 divided by 42 is 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1935.0
Subtracting 210 from 227 leaves us with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 42

Moving on to step 6:
42 can be fit into 171 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 19354.0
Deduct 168 from 171 and we're left 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.

Going ahead to step 7:
42 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 19354.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 42 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 19354.07
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 19354.071
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 19354.0714
If we subtract 168 from 180, we 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.

Advancing to step 11:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 19354.07142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 19354.071428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 19354.0714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
42 goes into 300 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 19354.07142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 19354.07142857, and the remainder is 6e-09.
