We're dividing 12723759 by 671 
We want to divide 12723759 by 671.

On to step 1:
671 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 671

Advancing to step 2:
When dividing 12 by 671, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 671

On to step 3:
671 goes into 127 0 times with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Grab the next digit (2) from the dividend, add it to 127, then carry on: 1272 / 671

Moving on to step 4:
The number 671 fits into 1272 1 times, leaving a remainder of 601.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 671 from 1272 to get 601.
Append the next digit (3) from the dividend to 601 and continue with: 6013 / 671

Going ahead to step 5:
671 can be fit into 6013 8 times, resulting in a remainder of 645.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 5368 from 6013, we get 645.
Include the next digit (7) from the dividend after 645, then repeat: 6457 / 671

Step 6:
If we divide 6457 by 671, we get 9 and a remainder of 418.
Record the quotient 9 as the next digit in the result. 
Result so far: 189.0
The remainder is 418 after subtracting 6039 from 6457.
Grab the next digit (5) from the dividend, add it to 418, then carry on: 4185 / 671

Advancing to step 7:
4185 divided by 671 is 6 with a remainder of 159.
Write down 6 as next digit of the result. 
Result so far: 1896.0
Deduct 4026 from 4185 and we're left with 159.
Grab the next digit (9) from the dividend, add it to 159, then carry on: 1599 / 671

Going ahead to step 8:
671 goes into 1599 2 times with a remainder of 257.
The number 2 becomes the next digit in our result. 
Result so far: 18962.0
The remainder is 257 after subtracting 1342 from 1599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 9:
The number 671 fits into 2570 3 times, leaving a remainder of 557.
Put 3 as the next digit of the answer. 
Result so far: 18962.3
If we take 2013 away from 2570, we end up with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Going ahead to step 10:
The number 671 fits into 5570 8 times, leaving a remainder of 202.
Record the quotient 8 as the next digit in the result. 
Result so far: 18962.38
The remainder is 202 after subtracting 5368 from 5570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 11:
2020 divided by 671 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 18962.383
The remainder is 7 after subtracting 2013 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
If we divide 70 by 671, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 18962.383
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
671 goes into 700 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 18962.38301
The remainder is 29 after subtracting 671 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
671 goes into 290 0 times with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 18962.38301
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 15:
671 goes into 2900 4 times with a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 18962.3830104
Deduct 2684 from 2900 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 16:
When dividing 2160 by 671, we get 3 with a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 18962.38301043
If we subtract 2013 from 2160, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

The final result is 18962.38301043 with a remainder of 1.47e-07.
