We divide 31593320 by 405
We're looking to find how many times 405 goes into 31593320.

Let's proceed to step 1:
When dividing 3 by 405, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 405

Moving on to step 2:
405 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 405

Let's proceed to step 3:
If we divide 315 by 405, we get 0 and a remainder of 315.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 315 after subtracting 0 from 315.
Bring next digit (9) of the dividend behind the 315 and repeat the process: 3159 / 405

On to step 4:
If we divide 3159 by 405, we get 7 and a remainder of 324.
The next digit of our result is 7. 
Result so far: 7.0
If we take 2835 away from 3159, we end up with 324.
Take the next digit (3) from the dividend and append it to 324, then repeat: 3243 / 405

Advancing to step 5:
When dividing 3243 by 405, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 3240 from 3243 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 405

Going ahead to step 6:
405 can be fit into 33 0 times, resulting in a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 780.0
Subtract 0 from 33 to get 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 405

On to step 7:
405 goes into 332 0 times with a remainder of 332.
Use 0 as the next digit of our solution. 
Result so far: 7800.0
Subtract 0 from 332 to get 332.
Include the next digit (0) from the dividend after 332, then repeat: 3320 / 405

Let's proceed to step 8:
405 can be fit into 3320 8 times, resulting in a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 78008.0
Deduct 3240 from 3320 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
When dividing 800 by 405, we get 1 with a remainder of 395.
Use 1 as the next digit of our solution. 
Result so far: 78008.1
Deduct 405 from 800 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 10:
When dividing 3950 by 405, we get 9 with a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 78008.19
The remainder is 305 after subtracting 3645 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 11:
3050 divided by 405 is 7 with a remainder of 215.
Write down 7 as next digit of the result. 
Result so far: 78008.197
Subtracting 2835 from 3050 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 12:
The number 405 fits into 2150 5 times, leaving a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 78008.1975
If we take 2025 away from 2150, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 13:
405 can be fit into 1250 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 78008.19753
If we take 1215 away from 1250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
If we divide 350 by 405, we get 0 and a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 78008.19753
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 15:
When dividing 3500 by 405, we get 8 with a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 78008.1975308
If we take 3240 away from 3500, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 16:
If we divide 2600 by 405, we get 6 and a remainder of 170.
Write down 6 as next digit of the result. 
Result so far: 78008.19753086
Subtracting 2430 from 2600 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 78008.19753086 with a balance of 1.7e-07.
