1521781 divided by 326 
Our goal is to divide 1521781 by 326.

On to step 1:
If we divide 1 by 326, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 326

On to step 2:
The number 326 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 326

On to step 3:
If we divide 152 by 326, we get 0 and a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 152 to get 152.
Grab the next digit (1) from the dividend, add it to 152, then carry on: 1521 / 326

Moving on to step 4:
If we divide 1521 by 326, we get 4 and a remainder of 217.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1304 from 1521, we get 217.
Include the next digit (7) from the dividend after 217, then repeat: 2177 / 326

On to step 5:
When dividing 2177 by 326, we get 6 with a remainder of 221.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtracting 1956 from 2177 leaves us with 221.
Bring next digit (8) of the dividend behind the 221 and repeat the process: 2218 / 326

Step 6:
When dividing 2218 by 326, we get 6 with a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 466.0
If we subtract 1956 from 2218, we get 262.
Grab the next digit (1) from the dividend, add it to 262, then carry on: 2621 / 326

Advancing to step 7:
326 goes into 2621 8 times with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 4668.0
Deduct 2608 from 2621 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
The number 326 fits into 130 0 times, leaving a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 4668.0
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 9:
The number 326 fits into 1300 3 times, leaving a remainder of 322.
Record the quotient 3 as the next digit in the result. 
Result so far: 4668.03
Deduct 978 from 1300 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 10:
326 can be fit into 3220 9 times, resulting in a remainder of 286.
The number 9 becomes the next digit in our result. 
Result so far: 4668.039
If we subtract 2934 from 3220, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 11:
2860 divided by 326 is 8 with a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 4668.0398
The remainder is 252 after subtracting 2608 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 12:
The number 326 fits into 2520 7 times, leaving a remainder of 238.
Write down 7 as next digit of the result. 
Result so far: 4668.03987
If we subtract 2282 from 2520, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 13:
If we divide 2380 by 326, we get 7 and a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 4668.039877
Subtracting 2282 from 2380 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

In conclusion, the division gives 4668.039877 with a balance of 9.8e-06.
