72410293 ÷ 405 
We want to divide 72410293 by 405.

Let's proceed to step 1:
The number 405 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 405

Moving on to step 2:
If we divide 72 by 405, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 405

Let's proceed to step 3:
405 can be fit into 724 1 times, resulting in a remainder of 319.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 319 after subtracting 405 from 724.
Fetch the next digit (1) from the dividend, attach it to 319 and continue: 3191 / 405

Moving on to step 4:
The number 405 fits into 3191 7 times, leaving a remainder of 356.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 2835 from 3191 and we're left with 356.
Append the next digit (0) from the dividend to 356 and continue with: 3560 / 405

Going ahead to step 5:
405 can be fit into 3560 8 times, resulting in a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
Deduct 3240 from 3560 and we're left with 320.
Bring next digit (2) of the dividend behind the 320 and repeat the process: 3202 / 405

On to step 6:
3202 divided by 405 is 7 with a remainder of 367.
Record the quotient 7 as the next digit in the result. 
Result so far: 1787.0
Subtracting 2835 from 3202 leaves us with 367.
Include the next digit (9) from the dividend after 367, then repeat: 3679 / 405

Moving on to step 7:
The number 405 fits into 3679 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 17879.0
If we take 3645 away from 3679, we end up with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 405

On to step 8:
If we divide 343 by 405, we get 0 and a remainder of 343.
The number 0 becomes the next digit in our result. 
Result so far: 178790.0
If we subtract 0 from 343, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 9:
405 goes into 3430 8 times with a remainder of 190.
The number 8 becomes the next digit in our result. 
Result so far: 178790.8
Subtracting 3240 from 3430 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
405 can be fit into 1900 4 times, resulting in a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 178790.84
If we take 1620 away from 1900, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
If we divide 2800 by 405, we get 6 and a remainder of 370.
Put 6 as the next digit of the answer. 
Result so far: 178790.846
Subtract 2430 from 2800 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 12:
The number 405 fits into 3700 9 times, leaving a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 178790.8469
Subtracting 3645 from 3700 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
If we divide 550 by 405, we get 1 and a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 178790.84691
If we subtract 405 from 550, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 14:
The number 405 fits into 1450 3 times, leaving a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 178790.846913
The remainder is 235 after subtracting 1215 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 15:
405 can be fit into 2350 5 times, resulting in a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 178790.8469135
If we subtract 2025 from 2350, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 16:
The number 405 fits into 3250 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 178790.84691358
The remainder is 10 after subtracting 3240 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 178790.84691358, with a leftover of 1e-08.
