We divide 13021890 by 723
Our goal is to divide 13021890 by 723.

Moving on to step 1:
If we divide 1 by 723, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 723

Advancing to step 2:
If we divide 13 by 723, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 723

On to step 3:
The number 723 fits into 130 0 times, leaving a remainder of 130.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 130, we get 130.
Fetch the next digit (2) from the dividend, attach it to 130 and continue: 1302 / 723

Advancing to step 4:
723 can be fit into 1302 1 times, resulting in a remainder of 579.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 723 from 1302 to get 579.
Take the next digit (1) from the dividend and append it to 579, then repeat: 5791 / 723

On to step 5:
5791 divided by 723 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 5784 from 5791 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 723

Moving on to step 6:
If we divide 78 by 723, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 723

On to step 7:
If we divide 789 by 723, we get 1 and a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 1801.0
Subtracting 723 from 789 leaves us with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 723

Advancing to step 8:
723 can be fit into 660 0 times, resulting in a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 18010.0
Subtract 0 from 660 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 9:
6600 divided by 723 is 9 with a remainder of 93.
Record the quotient 9 as the next digit in the result. 
Result so far: 18010.9
Subtracting 6507 from 6600 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 10:
723 can be fit into 930 1 times, resulting in a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 18010.91
If we subtract 723 from 930, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 11:
2070 divided by 723 is 2 with a remainder of 624.
The next digit of our result is 2. 
Result so far: 18010.912
The remainder is 624 after subtracting 1446 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 12:
723 can be fit into 6240 8 times, resulting in a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 18010.9128
If we subtract 5784 from 6240, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 13:
4560 divided by 723 is 6 with a remainder of 222.
Record the quotient 6 as the next digit in the result. 
Result so far: 18010.91286
Deduct 4338 from 4560 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.

On to step 14:
If we divide 2220 by 723, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 18010.912863
Subtracting 2169 from 2220 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 15:
When dividing 510 by 723, we get 0 with a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 18010.912863
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 16:
5100 divided by 723 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 18010.91286307
The remainder is 39 after subtracting 5061 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 18010.91286307, with a leftover of 3.9e-08.
