42073668 ÷ 978 
We're looking to find how many times 978 goes into 42073668.

Moving on to step 1:
If we divide 4 by 978, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 978

Going ahead to step 2:
978 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 978

Moving on to step 3:
If we divide 420 by 978, we get 0 and a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Append the next digit (7) from the dividend to 420 and continue with: 4207 / 978

Step 4:
When dividing 4207 by 978, we get 4 with a remainder of 295.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3912 from 4207 and we're left with 295.
Bring next digit (3) of the dividend behind the 295 and repeat the process: 2953 / 978

Step 5:
The number 978 fits into 2953 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 2934 from 2953 to get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 978

Advancing to step 6:
978 goes into 196 0 times with a remainder of 196.
The next digit of our result is 0. 
Result so far: 430.0
If we subtract 0 from 196, we get 196.
Grab the next digit (6) from the dividend, add it to 196, then carry on: 1966 / 978

Let's proceed to step 7:
If we divide 1966 by 978, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 4302.0
Deduct 1956 from 1966 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 978

On to step 8:
The number 978 fits into 108 0 times, leaving a remainder of 108.
Use 0 as the next digit of our solution. 
Result so far: 43020.0
Deduct 0 from 108 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
If we divide 1080 by 978, we get 1 and a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 43020.1
The remainder is 102 after subtracting 978 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
When dividing 1020 by 978, we get 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 43020.11
The remainder is 42 after subtracting 978 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 43020.11 with a remaining 0.042.
