We're dividing 1721563 by 872 
We want to divide 1721563 by 872.

On to step 1:
When dividing 1 by 872, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 872

On to step 2:
The number 872 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 872

Advancing to step 3:
The number 872 fits into 172 0 times, leaving a remainder of 172.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 172 and we're left with 172.
Take the next digit (1) from the dividend and append it to 172, then repeat: 1721 / 872

Step 4:
1721 divided by 872 is 1 with a remainder of 849.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 872 from 1721 leaves us with 849.
Fetch the next digit (5) from the dividend, attach it to 849 and continue: 8495 / 872

Let's proceed to step 5:
The number 872 fits into 8495 9 times, leaving a remainder of 647.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 7848 from 8495, we get 647.
Fetch the next digit (6) from the dividend, attach it to 647 and continue: 6476 / 872

Moving on to step 6:
872 can be fit into 6476 7 times, resulting in a remainder of 372.
Write down 7 as next digit of the result. 
Result so far: 197.0
Deduct 6104 from 6476 and we're left with 372.
Grab the next digit (3) from the dividend, add it to 372, then carry on: 3723 / 872

Moving on to step 7:
The number 872 fits into 3723 4 times, leaving a remainder of 235.
Record the quotient 4 as the next digit in the result. 
Result so far: 1974.0
Subtracting 3488 from 3723 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 8:
872 goes into 2350 2 times with a remainder of 606.
Write down 2 as next digit of the result. 
Result so far: 1974.2
Deduct 1744 from 2350 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Let's proceed to step 9:
If we divide 6060 by 872, we get 6 and a remainder of 828.
Record the quotient 6 as the next digit in the result. 
Result so far: 1974.26
Deduct 5232 from 6060 and we're left with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

On to step 10:
872 goes into 8280 9 times with a remainder of 432.
Record the quotient 9 as the next digit in the result. 
Result so far: 1974.269
If we take 7848 away from 8280, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 11:
When dividing 4320 by 872, we get 4 with a remainder of 832.
Use 4 as the next digit of our solution. 
Result so far: 1974.2694
Deduct 3488 from 4320 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 12:
The number 872 fits into 8320 9 times, leaving a remainder of 472.
The next digit of our result is 9. 
Result so far: 1974.26949
If we take 7848 away from 8320, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 13:
872 goes into 4720 5 times with a remainder of 360.
The number 5 becomes the next digit in our result. 
Result so far: 1974.269495
Deduct 4360 from 4720 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
If we divide 3600 by 872, we get 4 and a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 1974.2694954
The remainder is 112 after subtracting 3488 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 15:
872 goes into 1120 1 times with a remainder of 248.
The number 1 becomes the next digit in our result. 
Result so far: 1974.26949541
If we take 872 away from 1120, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

After the division, we end up with 1974.26949541 and a remainder of 2.48e-07.
