Let's divide 3967404 by 581
Let's see how many times 581 fits into 3967404.

Let's proceed to step 1:
If we divide 3 by 581, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 581

Let's proceed to step 2:
The number 581 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 581

On to step 3:
581 can be fit into 396 0 times, resulting in a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 396 after subtracting 0 from 396.
Take the next digit (7) from the dividend and append it to 396, then repeat: 3967 / 581

Step 4:
If we divide 3967 by 581, we get 6 and a remainder of 481.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 3486 from 3967 to get 481.
Take the next digit (4) from the dividend and append it to 481, then repeat: 4814 / 581

Going ahead to step 5:
581 goes into 4814 8 times with a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 4648 from 4814, we get 166.
Grab the next digit (0) from the dividend, add it to 166, then carry on: 1660 / 581

Advancing to step 6:
If we divide 1660 by 581, we get 2 and a remainder of 498.
Use 2 as the next digit of our solution. 
Result so far: 682.0
Deduct 1162 from 1660 and we're left with 498.
Grab the next digit (4) from the dividend, add it to 498, then carry on: 4984 / 581

Let's proceed to step 7:
The number 581 fits into 4984 8 times, leaving a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 6828.0
If we take 4648 away from 4984, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 8:
581 goes into 3360 5 times with a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 6828.5
If we subtract 2905 from 3360, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 9:
The number 581 fits into 4550 7 times, leaving a remainder of 483.
Put 7 as the next digit of the answer. 
Result so far: 6828.57
Subtract 4067 from 4550 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 10:
4830 divided by 581 is 8 with a remainder of 182.
Use 8 as the next digit of our solution. 
Result so far: 6828.578
If we take 4648 away from 4830, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 11:
581 goes into 1820 3 times with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 6828.5783
If we take 1743 away from 1820, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 12:
770 divided by 581 is 1 with a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 6828.57831
Subtracting 581 from 770 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 13:
1890 divided by 581 is 3 with a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 6828.578313
The remainder is 147 after subtracting 1743 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 14:
581 goes into 1470 2 times with a remainder of 308.
Put 2 as the next digit of the answer. 
Result so far: 6828.5783132
If we subtract 1162 from 1470, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 15:
The number 581 fits into 3080 5 times, leaving a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 6828.57831325
Subtract 2905 from 3080 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 6828.57831325, with a leftover of 1.75e-07.
