78436429 divided by 405 
We're looking to find how many times 405 goes into 78436429.

Moving on to step 1:
405 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 405

Moving on to step 2:
The number 405 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 405

Step 3:
When dividing 784 by 405, we get 1 with a remainder of 379.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 379 after subtracting 405 from 784.
Fetch the next digit (3) from the dividend, attach it to 379 and continue: 3793 / 405

Step 4:
3793 divided by 405 is 9 with a remainder of 148.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3645 from 3793 to get 148.
Append the next digit (6) from the dividend to 148 and continue with: 1486 / 405

Step 5:
When dividing 1486 by 405, we get 3 with a remainder of 271.
Put 3 as the next digit of the answer. 
Result so far: 193.0
Deduct 1215 from 1486 and we're left with 271.
Take the next digit (4) from the dividend and append it to 271, then repeat: 2714 / 405

Moving on to step 6:
2714 divided by 405 is 6 with a remainder of 284.
The next digit of our result is 6. 
Result so far: 1936.0
If we take 2430 away from 2714, we end up with 284.
Include the next digit (2) from the dividend after 284, then repeat: 2842 / 405

Going ahead to step 7:
405 goes into 2842 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 19367.0
The remainder is 7 after subtracting 2835 from 2842.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 405

Moving on to step 8:
The number 405 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 193670.0
If we subtract 0 from 79, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
The number 405 fits into 790 1 times, leaving a remainder of 385.
Use 1 as the next digit of our solution. 
Result so far: 193670.1
Subtract 405 from 790 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 10:
405 goes into 3850 9 times with a remainder of 205.
Write down 9 as next digit of the result. 
Result so far: 193670.19
If we take 3645 away from 3850, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
405 goes into 2050 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 193670.195
If we subtract 2025 from 2050, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
The number 405 fits into 250 0 times, leaving a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 193670.195
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 13:
When dividing 2500 by 405, we get 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 193670.19506
The remainder is 70 after subtracting 2430 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
If we divide 700 by 405, we get 1 and a remainder of 295.
Record the quotient 1 as the next digit in the result. 
Result so far: 193670.195061
If we subtract 405 from 700, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 15:
405 goes into 2950 7 times with a remainder of 115.
Write down 7 as next digit of the result. 
Result so far: 193670.1950617
Subtracting 2835 from 2950 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 16:
If we divide 1150 by 405, we get 2 and a remainder of 340.
The next digit of our result is 2. 
Result so far: 193670.19506172
Subtract 810 from 1150 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 193670.19506172, with a leftover of 3.4e-07.
