42857599 ÷ 671 
Our goal is to divide 42857599 by 671.

Moving on to step 1:
671 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 671

Step 4:
671 goes into 4285 6 times with a remainder of 259.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 4026 from 4285 to get 259.
Include the next digit (7) from the dividend after 259, then repeat: 2597 / 671

Going ahead to step 5:
671 goes into 2597 3 times with a remainder of 584.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 2013 from 2597 to get 584.
Grab the next digit (5) from the dividend, add it to 584, then carry on: 5845 / 671

Going ahead to step 6:
The number 671 fits into 5845 8 times, leaving a remainder of 477.
The number 8 becomes the next digit in our result. 
Result so far: 638.0
Deduct 5368 from 5845 and we're left with 477.
Grab the next digit (9) from the dividend, add it to 477, then carry on: 4779 / 671

Moving on to step 7:
When dividing 4779 by 671, we get 7 with a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 6387.0
If we take 4697 away from 4779, we end up with 82.
Append the next digit (9) from the dividend to 82 and continue with: 829 / 671

Step 8:
When dividing 829 by 671, we get 1 with a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 63871.0
Subtract 671 from 829 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
671 can be fit into 1580 2 times, resulting in a remainder of 238.
The next digit of our result is 2. 
Result so far: 63871.2
If we subtract 1342 from 1580, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 10:
671 can be fit into 2380 3 times, resulting in a remainder of 367.
The number 3 becomes the next digit in our result. 
Result so far: 63871.23
The remainder is 367 after subtracting 2013 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 11:
671 can be fit into 3670 5 times, resulting in a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 63871.235
The remainder is 315 after subtracting 3355 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 12:
If we divide 3150 by 671, we get 4 and a remainder of 466.
The number 4 becomes the next digit in our result. 
Result so far: 63871.2354
Deduct 2684 from 3150 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 13:
4660 divided by 671 is 6 with a remainder of 634.
Record the quotient 6 as the next digit in the result. 
Result so far: 63871.23546
If we subtract 4026 from 4660, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 14:
671 can be fit into 6340 9 times, resulting in a remainder of 301.
Record the quotient 9 as the next digit in the result. 
Result so far: 63871.235469
The remainder is 301 after subtracting 6039 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 15:
671 goes into 3010 4 times with a remainder of 326.
Write down 4 as next digit of the result. 
Result so far: 63871.2354694
Deduct 2684 from 3010 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 16:
671 can be fit into 3260 4 times, resulting in a remainder of 576.
The next digit of our result is 4. 
Result so far: 63871.23546944
Subtracting 2684 from 3260 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

After the division, we end up with 63871.23546944 and a remainder of 5.76e-07.
