The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 671

Going ahead to step 2:
If we divide 42 by 671, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 671

Advancing to step 3:
423 divided by 671 is 0 with a remainder of 423.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 423 and we're left with 423.
Append the next digit (4) from the dividend to 423 and continue with: 4234 / 671

Going ahead to step 4:
The number 671 fits into 4234 6 times, leaving a remainder of 208.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 4026 from 4234 to get 208.
Append the next digit (5) from the dividend to 208 and continue with: 2085 / 671

Advancing to step 5:
671 can be fit into 2085 3 times, resulting in a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtracting 2013 from 2085 leaves us with 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 671

Step 6:
The number 671 fits into 726 1 times, leaving a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 631.0
If we subtract 671 from 726, we get 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 671

Going ahead to step 7:
553 divided by 671 is 0 with a remainder of 553.
The number 0 becomes the next digit in our result. 
Result so far: 6310.0
If we take 0 away from 553, we end up with 553.
Fetch the next digit (4) from the dividend, attach it to 553 and continue: 5534 / 671

On to step 8:
The number 671 fits into 5534 8 times, leaving a remainder of 166.
The next digit of our result is 8. 
Result so far: 63108.0
Deduct 5368 from 5534 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
1660 divided by 671 is 2 with a remainder of 318.
Use 2 as the next digit of our solution. 
Result so far: 63108.2
If we take 1342 away from 1660, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 10:
When dividing 3180 by 671, we get 4 with a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 63108.24
Subtracting 2684 from 3180 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 11:
4960 divided by 671 is 7 with a remainder of 263.
Use 7 as the next digit of our solution. 
Result so far: 63108.247
Subtract 4697 from 4960 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 12:
The number 671 fits into 2630 3 times, leaving a remainder of 617.
The next digit of our result is 3. 
Result so far: 63108.2473
The remainder is 617 after subtracting 2013 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Step 13:
When dividing 6170 by 671, we get 9 with a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 63108.24739
If we take 6039 away from 6170, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 14:
671 goes into 1310 1 times with a remainder of 639.
The next digit of our result is 1. 
Result so far: 63108.247391
If we take 671 away from 1310, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Advancing to step 15:
671 can be fit into 6390 9 times, resulting in a remainder of 351.
The number 9 becomes the next digit in our result. 
Result so far: 63108.2473919
The remainder is 351 after subtracting 6039 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 16:
The number 671 fits into 3510 5 times, leaving a remainder of 155.
The next digit of our result is 5. 
Result so far: 63108.24739195
Subtract 3355 from 3510 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The quotient of the division is 63108.24739195, and the remainder is 1.55e-07.
