We divide 80568394 by 646
Let's see how many times 646 fits into 80568394.

Let's proceed to step 1:
When dividing 8 by 646, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 646

Going ahead to step 2:
The number 646 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 646

On to step 3:
The number 646 fits into 805 1 times, leaving a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 646 away from 805, we end up with 159.
Fetch the next digit (6) from the dividend, attach it to 159 and continue: 1596 / 646

Advancing to step 4:
646 can be fit into 1596 2 times, resulting in a remainder of 304.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1292 from 1596, we get 304.
Grab the next digit (8) from the dividend, add it to 304, then carry on: 3048 / 646

Let's proceed to step 5:
If we divide 3048 by 646, we get 4 and a remainder of 464.
The next digit of our result is 4. 
Result so far: 124.0
If we take 2584 away from 3048, we end up with 464.
Take the next digit (3) from the dividend and append it to 464, then repeat: 4643 / 646

Moving on to step 6:
If we divide 4643 by 646, we get 7 and a remainder of 121.
The number 7 becomes the next digit in our result. 
Result so far: 1247.0
If we take 4522 away from 4643, we end up with 121.
Include the next digit (9) from the dividend after 121, then repeat: 1219 / 646

Moving on to step 7:
When dividing 1219 by 646, we get 1 with a remainder of 573.
The number 1 becomes the next digit in our result. 
Result so far: 12471.0
If we take 646 away from 1219, we end up with 573.
Grab the next digit (4) from the dividend, add it to 573, then carry on: 5734 / 646

Let's proceed to step 8:
If we divide 5734 by 646, we get 8 and a remainder of 566.
The number 8 becomes the next digit in our result. 
Result so far: 124718.0
Deduct 5168 from 5734 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 9:
When dividing 5660 by 646, we get 8 with a remainder of 492.
Use 8 as the next digit of our solution. 
Result so far: 124718.8
If we subtract 5168 from 5660, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 10:
When dividing 4920 by 646, we get 7 with a remainder of 398.
Use 7 as the next digit of our solution. 
Result so far: 124718.87
If we subtract 4522 from 4920, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

On to step 11:
3980 divided by 646 is 6 with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 124718.876
Subtract 3876 from 3980 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
1040 divided by 646 is 1 with a remainder of 394.
Write down 1 as next digit of the result. 
Result so far: 124718.8761
The remainder is 394 after subtracting 646 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 13:
When dividing 3940 by 646, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 124718.87616
Deduct 3876 from 3940 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
646 can be fit into 640 0 times, resulting in a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 124718.87616
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 15:
The number 646 fits into 6400 9 times, leaving a remainder of 586.
Record the quotient 9 as the next digit in the result. 
Result so far: 124718.8761609
Subtracting 5814 from 6400 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Let's proceed to step 16:
If we divide 5860 by 646, we get 9 and a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 124718.87616099
Deduct 5814 from 5860 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 124718.87616099 and a remainder of 4.6e-08.
