We're dividing 398562 by 42 
We want to divide 398562 by 42.

Moving on to step 1:
42 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 42

Moving on to step 2:
If we divide 39 by 42, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 42

Moving on to step 3:
42 goes into 398 9 times with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 378 from 398 to get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 42

Advancing to step 4:
42 goes into 205 4 times with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtract 168 from 205 to get 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 42

Moving on to step 5:
If we divide 376 by 42, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 948.0
If we take 336 away from 376, we end up with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 42

On to step 6:
When dividing 402 by 42, we get 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 9489.0
If we take 378 away from 402, we end up with 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 7:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9489.5
Subtracting 210 from 240 leaves us 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.

Advancing to step 8:
If we divide 300 by 42, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 9489.57
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
42 goes into 60 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 9489.571
If we take 42 away from 60, we end up 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.

Moving on to step 10:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 9489.5714
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.

Step 11:
When dividing 120 by 42, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 9489.57142
Subtracting 84 from 120 leaves us 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.

Step 12:
When dividing 360 by 42, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 9489.571428
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.

On to step 13:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9489.5714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 42 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 9489.57142857
If we take 294 away from 300, we end up with 6.
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 9489.57142857, and the remainder is 6e-09.
