3989291 ÷ 577 
We want to divide 3989291 by 577.

Let's proceed to step 1:
If we divide 3 by 577, we get 0 and a remainder of 3.
Write down 0 as next digit of the 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 / 577

Let's proceed to step 2:
If we divide 39 by 577, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 577

On to step 3:
When dividing 398 by 577, we get 0 with a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 398 after subtracting 0 from 398.
Bring next digit (9) of the dividend behind the 398 and repeat the process: 3989 / 577

On to step 4:
If we divide 3989 by 577, we get 6 and a remainder of 527.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3462 from 3989 to get 527.
Append the next digit (2) from the dividend to 527 and continue with: 5272 / 577

Let's proceed to step 5:
The number 577 fits into 5272 9 times, leaving a remainder of 79.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 5193 from 5272 to get 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 577

Step 6:
The number 577 fits into 799 1 times, leaving a remainder of 222.
Write down 1 as next digit of the result. 
Result so far: 691.0
The remainder is 222 after subtracting 577 from 799.
Include the next digit (1) from the dividend after 222, then repeat: 2221 / 577

Let's proceed to step 7:
The number 577 fits into 2221 3 times, leaving a remainder of 490.
Write down 3 as next digit of the result. 
Result so far: 6913.0
If we take 1731 away from 2221, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 8:
577 goes into 4900 8 times with a remainder of 284.
Use 8 as the next digit of our solution. 
Result so far: 6913.8
Deduct 4616 from 4900 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 9:
The number 577 fits into 2840 4 times, leaving a remainder of 532.
Write down 4 as next digit of the result. 
Result so far: 6913.84
If we subtract 2308 from 2840, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 10:
5320 divided by 577 is 9 with a remainder of 127.
The number 9 becomes the next digit in our result. 
Result so far: 6913.849
Subtracting 5193 from 5320 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 11:
The number 577 fits into 1270 2 times, leaving a remainder of 116.
Record the quotient 2 as the next digit in the result. 
Result so far: 6913.8492
If we take 1154 away from 1270, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 12:
577 can be fit into 1160 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 6913.84922
Subtract 1154 from 1160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 6913.84922 with a balance of 6e-06.
