3935204 ÷ 978 
We're looking to find how many times 978 goes into 3935204.

On to step 1:
978 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 978

Going ahead to step 2:
If we divide 39 by 978, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 978

Advancing to step 3:
If we divide 393 by 978, we get 0 and a remainder of 393.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 393, we end up with 393.
Include the next digit (5) from the dividend after 393, then repeat: 3935 / 978

Advancing to step 4:
The number 978 fits into 3935 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3912 from 3935, we get 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 978

Step 5:
When dividing 232 by 978, we get 0 with a remainder of 232.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtracting 0 from 232 leaves us with 232.
Take the next digit (0) from the dividend and append it to 232, then repeat: 2320 / 978

Let's proceed to step 6:
If we divide 2320 by 978, we get 2 and a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 402.0
If we take 1956 away from 2320, we end up with 364.
Bring next digit (4) of the dividend behind the 364 and repeat the process: 3644 / 978

Advancing to step 7:
The number 978 fits into 3644 3 times, leaving a remainder of 710.
The number 3 becomes the next digit in our result. 
Result so far: 4023.0
Subtracting 2934 from 3644 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 8:
7100 divided by 978 is 7 with a remainder of 254.
Use 7 as the next digit of our solution. 
Result so far: 4023.7
If we take 6846 away from 7100, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 9:
2540 divided by 978 is 2 with a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 4023.72
The remainder is 584 after subtracting 1956 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 10:
5840 divided by 978 is 5 with a remainder of 950.
Record the quotient 5 as the next digit in the result. 
Result so far: 4023.725
Subtracting 4890 from 5840 leaves us with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Going ahead to step 11:
The number 978 fits into 9500 9 times, leaving a remainder of 698.
Put 9 as the next digit of the answer. 
Result so far: 4023.7259
If we take 8802 away from 9500, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 12:
When dividing 6980 by 978, we get 7 with a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 4023.72597
Deduct 6846 from 6980 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 13:
978 can be fit into 1340 1 times, resulting in a remainder of 362.
Put 1 as the next digit of the answer. 
Result so far: 4023.725971
If we take 978 away from 1340, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 14:
978 goes into 3620 3 times with a remainder of 686.
The number 3 becomes the next digit in our result. 
Result so far: 4023.7259713
Subtracting 2934 from 3620 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 15:
The number 978 fits into 6860 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4023.72597137
Subtract 6846 from 6860 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 4023.72597137 and a remainder of 1.4e-08.
