6444457 ÷ 857 
We want to divide 6444457 by 857.

Step 1:
857 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 857

Going ahead to step 2:
857 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 857

Step 3:
857 goes into 644 0 times with a remainder of 644.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 644 leaves us with 644.
Take the next digit (4) from the dividend and append it to 644, then repeat: 6444 / 857

On to step 4:
857 goes into 6444 7 times with a remainder of 445.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 5999 from 6444 and we're left with 445.
Bring next digit (4) of the dividend behind the 445 and repeat the process: 4454 / 857

Step 5:
857 goes into 4454 5 times with a remainder of 169.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 4285 away from 4454, we end up with 169.
Include the next digit (5) from the dividend after 169, then repeat: 1695 / 857

Advancing to step 6:
1695 divided by 857 is 1 with a remainder of 838.
The number 1 becomes the next digit in our result. 
Result so far: 751.0
If we take 857 away from 1695, we end up with 838.
Append the next digit (7) from the dividend to 838 and continue with: 8387 / 857

Going ahead to step 7:
The number 857 fits into 8387 9 times, leaving a remainder of 674.
The number 9 becomes the next digit in our result. 
Result so far: 7519.0
The remainder is 674 after subtracting 7713 from 8387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Advancing to step 8:
6740 divided by 857 is 7 with a remainder of 741.
Use 7 as the next digit of our solution. 
Result so far: 7519.7
Subtracting 5999 from 6740 leaves us with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Moving on to step 9:
The number 857 fits into 7410 8 times, leaving a remainder of 554.
Put 8 as the next digit of the answer. 
Result so far: 7519.78
Subtracting 6856 from 7410 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Let's proceed to step 10:
When dividing 5540 by 857, we get 6 with a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 7519.786
Subtracting 5142 from 5540 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 11:
857 goes into 3980 4 times with a remainder of 552.
Use 4 as the next digit of our solution. 
Result so far: 7519.7864
The remainder is 552 after subtracting 3428 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 12:
When dividing 5520 by 857, we get 6 with a remainder of 378.
Put 6 as the next digit of the answer. 
Result so far: 7519.78646
If we subtract 5142 from 5520, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 13:
857 goes into 3780 4 times with a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 7519.786464
If we subtract 3428 from 3780, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 14:
When dividing 3520 by 857, we get 4 with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 7519.7864644
Subtract 3428 from 3520 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 7519.7864644 with a remaining 9.2e-07.
