We look at the division of 829964 by 42 
We want to figure out the number of times 829964 can be divided by 42.

Advancing to 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
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 42

Advancing to step 2:
The number 42 fits into 82 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 82, we end up with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 42

Advancing to step 3:
If we divide 409 by 42, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 378 away from 409, we end up with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 42

Step 4:
If we divide 319 by 42, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
Subtracting 294 from 319 leaves us with 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 42

Advancing to step 5:
42 can be fit into 256 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1976.0
If we subtract 252 from 256, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 42

Advancing to step 6:
42 goes into 44 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 19761.0
If we subtract 42 from 44, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 42 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19761.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 19761.04
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 19761.047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
When dividing 260 by 42, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 19761.0476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
42 goes into 80 1 times with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 19761.04761
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.

Going ahead to step 12:
42 goes into 380 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19761.047619
Subtracting 378 from 380 leaves us 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.

Advancing to step 13:
42 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19761.047619
If we take 0 away from 20, we end up with 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 14:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 19761.04761904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 19761.04761904, and the remainder is 3.2e-08.
