We look at the division of 978901 by 42 
Let's see how many times 42 fits into 978901.

Let's proceed to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 42

Advancing to step 2:
42 can be fit into 97 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
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

Let's proceed to step 3:
42 can be fit into 138 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 12 after subtracting 126 from 138.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 42

Step 4:
When dividing 129 by 42, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 233.0
The remainder is 3 after subtracting 126 from 129.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 42

Let's proceed to step 5:
42 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2330.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 42

Moving on to step 6:
If we divide 301 by 42, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 23307.0
Deduct 294 from 301 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
42 can be fit into 70 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 23307.1
Subtracting 42 from 70 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
If we divide 280 by 42, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 23307.16
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
If we divide 280 by 42, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 23307.166
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 23307.166 and a remainder of 0.0028.
