We look at the division of 3964530 by 980 
We want to figure out the number of times 3964530 can be divided by 980.

Step 1:
If we divide 3 by 980, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 980

Advancing to step 2:
If we divide 39 by 980, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 980

Advancing to step 3:
The number 980 fits into 396 0 times, leaving a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 396 leaves us with 396.
Take the next digit (4) from the dividend and append it to 396, then repeat: 3964 / 980

On to step 4:
3964 divided by 980 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3920 from 3964 and we're left with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 980

On to step 5:
445 divided by 980 is 0 with a remainder of 445.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 445 leaves us with 445.
Fetch the next digit (3) from the dividend, attach it to 445 and continue: 4453 / 980

Moving on to step 6:
4453 divided by 980 is 4 with a remainder of 533.
The number 4 becomes the next digit in our result. 
Result so far: 404.0
Subtracting 3920 from 4453 leaves us with 533.
Bring next digit (0) of the dividend behind the 533 and repeat the process: 5330 / 980

Step 7:
When dividing 5330 by 980, we get 5 with a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 4045.0
If we subtract 4900 from 5330, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 8:
980 goes into 4300 4 times with a remainder of 380.
Write down 4 as next digit of the result. 
Result so far: 4045.4
The remainder is 380 after subtracting 3920 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 9:
980 can be fit into 3800 3 times, resulting in a remainder of 860.
Write down 3 as next digit of the result. 
Result so far: 4045.43
The remainder is 860 after subtracting 2940 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Moving on to step 10:
980 goes into 8600 8 times with a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 4045.438
If we take 7840 away from 8600, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 11:
When dividing 7600 by 980, we get 7 with a remainder of 740.
Use 7 as the next digit of our solution. 
Result so far: 4045.4387
Subtracting 6860 from 7600 leaves us 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.

Going ahead to step 12:
980 goes into 7400 7 times with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 4045.43877
The remainder is 540 after subtracting 6860 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Our division results in 4045.43877 with a remaining 0.00054.
