39884712 ÷ 978 
We want to divide 39884712 by 978.

Step 1:
When dividing 3 by 978, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 978

Moving on to step 2:
978 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 978

Let's proceed to step 3:
398 divided by 978 is 0 with a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 398, we get 398.
Bring next digit (8) of the dividend behind the 398 and repeat the process: 3988 / 978

Let's proceed to step 4:
978 goes into 3988 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3912 from 3988, we get 76.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 978

Let's proceed to step 5:
When dividing 764 by 978, we get 0 with a remainder of 764.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 764, we get 764.
Include the next digit (7) from the dividend after 764, then repeat: 7647 / 978

Going ahead to step 6:
The number 978 fits into 7647 7 times, leaving a remainder of 801.
Put 7 as the next digit of the answer. 
Result so far: 407.0
Subtract 6846 from 7647 to get 801.
Fetch the next digit (1) from the dividend, attach it to 801 and continue: 8011 / 978

Step 7:
978 goes into 8011 8 times with a remainder of 187.
Record the quotient 8 as the next digit in the result. 
Result so far: 4078.0
Deduct 7824 from 8011 and we're left with 187.
Grab the next digit (2) from the dividend, add it to 187, then carry on: 1872 / 978

Advancing to step 8:
1872 divided by 978 is 1 with a remainder of 894.
Record the quotient 1 as the next digit in the result. 
Result so far: 40781.0
Subtract 978 from 1872 to get 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

Moving on to step 9:
If we divide 8940 by 978, we get 9 and a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 40781.9
Deduct 8802 from 8940 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 10:
If we divide 1380 by 978, we get 1 and a remainder of 402.
The number 1 becomes the next digit in our result. 
Result so far: 40781.91
The remainder is 402 after subtracting 978 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 11:
4020 divided by 978 is 4 with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 40781.914
Subtracting 3912 from 4020 leaves us 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.

Going ahead to step 12:
978 can be fit into 1080 1 times, resulting in a remainder of 102.
The next digit of our result is 1. 
Result so far: 40781.9141
If we subtract 978 from 1080, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 13:
The number 978 fits into 1020 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 40781.91411
If we subtract 978 from 1020, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 40781.91411 with a balance of 4.2e-05.
