978215 divided by 42 
Our goal is to divide 978215 by 42.

Going ahead to step 1:
If we divide 9 by 42, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 42

Step 2:
If we divide 97 by 42, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 84 from 97, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 42

On to step 3:
42 goes into 138 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 12 after subtracting 126 from 138.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 42

Going ahead to step 4:
The number 42 fits into 122 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 232.0
Subtract 84 from 122 to get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 42

Moving on to step 5:
If we divide 381 by 42, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 2329.0
If we take 378 away from 381, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 42

Let's proceed to step 6:
42 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 23290.0
If we subtract 0 from 35, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
42 goes into 350 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 23290.8
Deduct 336 from 350 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 42, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 23290.83
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 23290.833
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 23290.833 with a remaining 0.0014.
