828258 divided by 42 
We want to divide 828258 by 42.

Step 1:
42 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 42

Moving on to step 2:
42 can be fit into 82 1 times, resulting in a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
If we take 42 away from 82, we end up with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 42

Step 3:
If we divide 408 by 42, we get 9 and a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 378 from 408 leaves us with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 42

Going ahead to step 4:
When dividing 302 by 42, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Subtracting 294 from 302 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 42

Going ahead to step 5:
85 divided by 42 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1972.0
Subtracting 84 from 85 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 42

Advancing to step 6:
42 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 19720.0
If we subtract 0 from 18, we 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.

Moving on to step 7:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 19720.4
Subtract 168 from 180 to 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.

Going ahead to step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 19720.42
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 19720.428
If we subtract 336 from 360, we 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.

On to step 10:
42 goes into 240 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 19720.4285
Deduct 210 from 240 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.

Moving on to step 11:
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: 19720.42857
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.

On to step 12:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 19720.428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 19720.4285714
Deduct 168 from 180 and we're left with 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 14:
If we divide 120 by 42, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 19720.42857142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 19720.42857142 with a remaining 3.6e-08.
