871492 divided by 42 
We want to divide 871492 by 42.

Step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 42

Advancing to step 2:
When dividing 87 by 42, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 84 from 87 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 42

Let's proceed to step 3:
When dividing 31 by 42, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 31, we get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 42

Advancing to step 4:
42 goes into 314 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we take 294 away from 314, we end up with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 42

Moving on to step 5:
The number 42 fits into 209 4 times, leaving a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 2074.0
Subtracting 168 from 209 leaves us with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 42

Step 6:
If we divide 412 by 42, we get 9 and a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 20749.0
If we subtract 378 from 412, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 20749.8
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 20749.8
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 20749.809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
220 divided by 42 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 20749.8095
If we take 210 away from 220, we end up 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.

Moving on to step 11:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 20749.80952
Subtracting 84 from 100 leaves us 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.

Step 12:
When dividing 160 by 42, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 20749.809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
340 divided by 42 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 20749.8095238
If we take 336 away from 340, we end up 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.

Let's proceed to step 14:
When dividing 40 by 42, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 20749.8095238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 20749.8095238 with a remainder of 4e-08.
