78777694 divided by 405 
We want to divide 78777694 by 405.

Moving on to step 1:
When dividing 7 by 405, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 405

Moving on to step 2:
If we divide 78 by 405, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 405

Let's proceed to step 3:
405 goes into 787 1 times with a remainder of 382.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 382 after subtracting 405 from 787.
Include the next digit (7) from the dividend after 382, then repeat: 3827 / 405

Advancing to step 4:
405 goes into 3827 9 times with a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 3645 from 3827 leaves us with 182.
Take the next digit (7) from the dividend and append it to 182, then repeat: 1827 / 405

Let's proceed to step 5:
1827 divided by 405 is 4 with a remainder of 207.
Write down 4 as next digit of the result. 
Result so far: 194.0
Subtract 1620 from 1827 to get 207.
Append the next digit (6) from the dividend to 207 and continue with: 2076 / 405

On to step 6:
2076 divided by 405 is 5 with a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 1945.0
Subtracting 2025 from 2076 leaves us with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 405

Let's proceed to step 7:
405 can be fit into 519 1 times, resulting in a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 19451.0
If we subtract 405 from 519, we get 114.
Fetch the next digit (4) from the dividend, attach it to 114 and continue: 1144 / 405

Let's proceed to step 8:
1144 divided by 405 is 2 with a remainder of 334.
The next digit of our result is 2. 
Result so far: 194512.0
If we take 810 away from 1144, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 9:
If we divide 3340 by 405, we get 8 and a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 194512.8
Deduct 3240 from 3340 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
405 goes into 1000 2 times with a remainder of 190.
Use 2 as the next digit of our solution. 
Result so far: 194512.82
Subtract 810 from 1000 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
405 goes into 1900 4 times with a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 194512.824
If we subtract 1620 from 1900, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
2800 divided by 405 is 6 with a remainder of 370.
Write down 6 as next digit of the result. 
Result so far: 194512.8246
The remainder is 370 after subtracting 2430 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 13:
3700 divided by 405 is 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 194512.82469
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 14:
405 goes into 550 1 times with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 194512.824691
The remainder is 145 after subtracting 405 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 15:
405 can be fit into 1450 3 times, resulting in a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 194512.8246913
If we take 1215 away from 1450, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 16:
2350 divided by 405 is 5 with a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 194512.82469135
If we take 2025 away from 2350, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The quotient of the division is 194512.82469135, and the remainder is 3.25e-07.
