2488510 ÷ 671 
We want to figure out the number of times 2488510 can be divided by 671.

Going ahead to step 1:
If we divide 2 by 671, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 671

Advancing to step 2:
When dividing 24 by 671, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 671

Moving on to step 3:
When dividing 248 by 671, we get 0 with a remainder of 248.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 248 and we're left with 248.
Grab the next digit (8) from the dividend, add it to 248, then carry on: 2488 / 671

Advancing to step 4:
The number 671 fits into 2488 3 times, leaving a remainder of 475.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2013 from 2488 leaves us with 475.
Take the next digit (5) from the dividend and append it to 475, then repeat: 4755 / 671

Let's proceed to step 5:
671 goes into 4755 7 times with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 4697 away from 4755, we end up with 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 671

Advancing to step 6:
671 can be fit into 581 0 times, resulting in a remainder of 581.
The number 0 becomes the next digit in our result. 
Result so far: 370.0
The remainder is 581 after subtracting 0 from 581.
Bring next digit (0) of the dividend behind the 581 and repeat the process: 5810 / 671

Moving on to step 7:
671 can be fit into 5810 8 times, resulting in a remainder of 442.
The next digit of our result is 8. 
Result so far: 3708.0
The remainder is 442 after subtracting 5368 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 8:
The number 671 fits into 4420 6 times, leaving a remainder of 394.
Put 6 as the next digit of the answer. 
Result so far: 3708.6
The remainder is 394 after subtracting 4026 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 9:
671 goes into 3940 5 times with a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 3708.65
Subtract 3355 from 3940 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 10:
671 can be fit into 5850 8 times, resulting in a remainder of 482.
The number 8 becomes the next digit in our result. 
Result so far: 3708.658
Deduct 5368 from 5850 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 11:
671 can be fit into 4820 7 times, resulting in a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 3708.6587
Deduct 4697 from 4820 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 12:
671 goes into 1230 1 times with a remainder of 559.
The number 1 becomes the next digit in our result. 
Result so far: 3708.65871
If we subtract 671 from 1230, we get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Moving on to step 13:
5590 divided by 671 is 8 with a remainder of 222.
Write down 8 as next digit of the result. 
Result so far: 3708.658718
Deduct 5368 from 5590 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 14:
2220 divided by 671 is 3 with a remainder of 207.
The number 3 becomes the next digit in our result. 
Result so far: 3708.6587183
If we take 2013 away from 2220, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 15:
When dividing 2070 by 671, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 3708.65871833
If we take 2013 away from 2070, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 3708.65871833 with a remaining 5.7e-08.
