32399988 ÷ 405 
Our goal is to divide 32399988 by 405.

Going ahead to step 1:
If we divide 3 by 405, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 405

Advancing to step 2:
When dividing 32 by 405, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 405

On to step 3:
405 can be fit into 323 0 times, resulting in a remainder of 323.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 323, we get 323.
Fetch the next digit (9) from the dividend, attach it to 323 and continue: 3239 / 405

Advancing to step 4:
The number 405 fits into 3239 7 times, leaving a remainder of 404.
The next digit of our result is 7. 
Result so far: 7.0
If we take 2835 away from 3239, we end up with 404.
Append the next digit (9) from the dividend to 404 and continue with: 4049 / 405

Moving on to step 5:
405 can be fit into 4049 9 times, resulting in a remainder of 404.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 3645 from 4049 leaves us with 404.
Fetch the next digit (9) from the dividend, attach it to 404 and continue: 4049 / 405

Let's proceed to step 6:
405 can be fit into 4049 9 times, resulting in a remainder of 404.
The number 9 becomes the next digit in our result. 
Result so far: 799.0
Subtracting 3645 from 4049 leaves us with 404.
Bring next digit (8) of the dividend behind the 404 and repeat the process: 4048 / 405

Advancing to step 7:
4048 divided by 405 is 9 with a remainder of 403.
The next digit of our result is 9. 
Result so far: 7999.0
If we subtract 3645 from 4048, we get 403.
Append the next digit (8) from the dividend to 403 and continue with: 4038 / 405

Going ahead to step 8:
4038 divided by 405 is 9 with a remainder of 393.
Use 9 as the next digit of our solution. 
Result so far: 79999.0
Subtracting 3645 from 4038 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 9:
405 goes into 3930 9 times with a remainder of 285.
Record the quotient 9 as the next digit in the result. 
Result so far: 79999.9
The remainder is 285 after subtracting 3645 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 10:
If we divide 2850 by 405, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 79999.97
Subtract 2835 from 2850 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
If we divide 150 by 405, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 79999.97
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
If we divide 1500 by 405, we get 3 and a remainder of 285.
Use 3 as the next digit of our solution. 
Result so far: 79999.9703
Deduct 1215 from 1500 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 13:
The number 405 fits into 2850 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 79999.97037
The remainder is 15 after subtracting 2835 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
The number 405 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 79999.97037
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 15:
405 can be fit into 1500 3 times, resulting in a remainder of 285.
The next digit of our result is 3. 
Result so far: 79999.9703703
The remainder is 285 after subtracting 1215 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 16:
The number 405 fits into 2850 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 79999.97037037
Deduct 2835 from 2850 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 79999.97037037 and a remainder of 1.5e-08.
