We divide 8078639 by 394
Our goal is to divide 8078639 by 394.

Going ahead to step 1:
The number 394 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 394

Moving on to step 2:
394 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 394

Step 3:
If we divide 807 by 394, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 788 from 807 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 394

On to step 4:
394 can be fit into 198 0 times, resulting in a remainder of 198.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 198 after subtracting 0 from 198.
Append the next digit (6) from the dividend to 198 and continue with: 1986 / 394

Moving on to step 5:
394 goes into 1986 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 205.0
If we take 1970 away from 1986, we end up with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 394

Let's proceed to step 6:
394 goes into 163 0 times with a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 2050.0
Subtract 0 from 163 to get 163.
Append the next digit (9) from the dividend to 163 and continue with: 1639 / 394

Advancing to step 7:
394 goes into 1639 4 times with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 20504.0
Subtracting 1576 from 1639 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
The number 394 fits into 630 1 times, leaving a remainder of 236.
The next digit of our result is 1. 
Result so far: 20504.1
Subtracting 394 from 630 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
If we divide 2360 by 394, we get 5 and a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 20504.15
The remainder is 390 after subtracting 1970 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
When dividing 3900 by 394, we get 9 with a remainder of 354.
The number 9 becomes the next digit in our result. 
Result so far: 20504.159
If we take 3546 away from 3900, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 11:
394 can be fit into 3540 8 times, resulting in a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 20504.1598
If we subtract 3152 from 3540, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 12:
3880 divided by 394 is 9 with a remainder of 334.
The number 9 becomes the next digit in our result. 
Result so far: 20504.15989
Subtracting 3546 from 3880 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 13:
3340 divided by 394 is 8 with a remainder of 188.
Put 8 as the next digit of the answer. 
Result so far: 20504.159898
Deduct 3152 from 3340 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 14:
If we divide 1880 by 394, we get 4 and a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 20504.1598984
If we take 1576 away from 1880, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
394 goes into 3040 7 times with a remainder of 282.
The next digit of our result is 7. 
Result so far: 20504.15989847
Deduct 2758 from 3040 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

The final outcome is 20504.15989847, with a leftover of 2.82e-07.
