12328188 ÷ 721 
Our goal is to divide 12328188 by 721.

Let's proceed to step 1:
721 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 721

Let's proceed to step 2:
When dividing 12 by 721, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 721

Let's proceed to step 3:
721 can be fit into 123 0 times, resulting in a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Fetch the next digit (2) from the dividend, attach it to 123 and continue: 1232 / 721

Moving on to step 4:
1232 divided by 721 is 1 with a remainder of 511.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 721 from 1232 and we're left with 511.
Grab the next digit (8) from the dividend, add it to 511, then carry on: 5118 / 721

Step 5:
5118 divided by 721 is 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 5047 from 5118, we get 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 721

Step 6:
711 divided by 721 is 0 with a remainder of 711.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtract 0 from 711 to get 711.
Bring next digit (8) of the dividend behind the 711 and repeat the process: 7118 / 721

On to step 7:
The number 721 fits into 7118 9 times, leaving a remainder of 629.
The next digit of our result is 9. 
Result so far: 1709.0
Deduct 6489 from 7118 and we're left with 629.
Grab the next digit (8) from the dividend, add it to 629, then carry on: 6298 / 721

Advancing to step 8:
If we divide 6298 by 721, we get 8 and a remainder of 530.
The number 8 becomes the next digit in our result. 
Result so far: 17098.0
If we subtract 5768 from 6298, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 9:
If we divide 5300 by 721, we get 7 and a remainder of 253.
The next digit of our result is 7. 
Result so far: 17098.7
If we take 5047 away from 5300, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 10:
721 can be fit into 2530 3 times, resulting in a remainder of 367.
Record the quotient 3 as the next digit in the result. 
Result so far: 17098.73
Deduct 2163 from 2530 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 11:
If we divide 3670 by 721, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 17098.735
If we subtract 3605 from 3670, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
When dividing 650 by 721, we get 0 with a remainder of 650.
The number 0 becomes the next digit in our result. 
Result so far: 17098.735
If we take 0 away from 650, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 13:
When dividing 6500 by 721, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 17098.73509
Subtracting 6489 from 6500 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
110 divided by 721 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 17098.73509
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 15:
If we divide 1100 by 721, we get 1 and a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 17098.7350901
The remainder is 379 after subtracting 721 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 16:
721 goes into 3790 5 times with a remainder of 185.
The next digit of our result is 5. 
Result so far: 17098.73509015
If we take 3605 away from 3790, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

In conclusion, the division gives 17098.73509015 with a balance of 1.85e-07.
