Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 978

Advancing to step 2:
978 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 978

Let's proceed to step 3:
The number 978 fits into 420 0 times, leaving a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Grab the next digit (9) from the dividend, add it to 420, then carry on: 4209 / 978

Let's proceed to step 4:
When dividing 4209 by 978, we get 4 with a remainder of 297.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 297 after subtracting 3912 from 4209.
Include the next digit (9) from the dividend after 297, then repeat: 2979 / 978

Going ahead to step 5:
2979 divided by 978 is 3 with a remainder of 45.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 2934 from 2979, we get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 978

Step 6:
978 can be fit into 450 0 times, resulting in a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 430.0
The remainder is 450 after subtracting 0 from 450.
Take the next digit (7) from the dividend and append it to 450, then repeat: 4507 / 978

Advancing to step 7:
4507 divided by 978 is 4 with a remainder of 595.
Write down 4 as next digit of the result. 
Result so far: 4304.0
Subtract 3912 from 4507 to get 595.
Append the next digit (1) from the dividend to 595 and continue with: 5951 / 978

Let's proceed to step 8:
978 goes into 5951 6 times with a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 43046.0
Deduct 5868 from 5951 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
978 can be fit into 830 0 times, resulting in a remainder of 830.
The number 0 becomes the next digit in our result. 
Result so far: 43046.0
Deduct 0 from 830 and we're left with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Going ahead to step 10:
When dividing 8300 by 978, we get 8 with a remainder of 476.
Write down 8 as next digit of the result. 
Result so far: 43046.08
Subtract 7824 from 8300 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 11:
978 can be fit into 4760 4 times, resulting in a remainder of 848.
Put 4 as the next digit of the answer. 
Result so far: 43046.084
Deduct 3912 from 4760 and we're left with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Going ahead to step 12:
978 goes into 8480 8 times with a remainder of 656.
Record the quotient 8 as the next digit in the result. 
Result so far: 43046.0848
If we subtract 7824 from 8480, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 13:
6560 divided by 978 is 6 with a remainder of 692.
Write down 6 as next digit of the result. 
Result so far: 43046.08486
The remainder is 692 after subtracting 5868 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 14:
978 can be fit into 6920 7 times, resulting in a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 43046.084867
Subtract 6846 from 6920 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 15:
If we divide 740 by 978, we get 0 and a remainder of 740.
The next digit of our result is 0. 
Result so far: 43046.084867
Deduct 0 from 740 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 16:
If we divide 7400 by 978, we get 7 and a remainder of 554.
The next digit of our result is 7. 
Result so far: 43046.08486707
The remainder is 554 after subtracting 6846 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

In conclusion, the division gives 43046.08486707 with a balance of 5.54e-07.
