7797700 ÷ 405 
We want to figure out the number of times 7797700 can be divided by 405.

On to step 1:
405 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 405

Advancing to step 2:
405 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 405

On to step 3:
The number 405 fits into 779 1 times, leaving a remainder of 374.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 405 away from 779, we end up with 374.
Grab the next digit (7) from the dividend, add it to 374, then carry on: 3747 / 405

Moving on to step 4:
3747 divided by 405 is 9 with a remainder of 102.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 3645 from 3747 to get 102.
Bring next digit (7) of the dividend behind the 102 and repeat the process: 1027 / 405

Moving on to step 5:
405 can be fit into 1027 2 times, resulting in a remainder of 217.
Write down 2 as next digit of the result. 
Result so far: 192.0
Deduct 810 from 1027 and we're left with 217.
Append the next digit (0) from the dividend to 217 and continue with: 2170 / 405

Advancing to step 6:
2170 divided by 405 is 5 with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 1925.0
If we take 2025 away from 2170, we end up with 145.
Append the next digit (0) from the dividend to 145 and continue with: 1450 / 405

Let's proceed to step 7:
405 can be fit into 1450 3 times, resulting in a remainder of 235.
The next digit of our result is 3. 
Result so far: 19253.0
Subtract 1215 from 1450 to get 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 8:
405 can be fit into 2350 5 times, resulting in a remainder of 325.
The next digit of our result is 5. 
Result so far: 19253.5
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.

Going ahead to step 9:
405 goes into 3250 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 19253.58
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.

Step 10:
100 divided by 405 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 19253.58
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
1000 divided by 405 is 2 with a remainder of 190.
The next digit of our result is 2. 
Result so far: 19253.5802
Subtracting 810 from 1000 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.

Advancing to step 12:
When dividing 1900 by 405, we get 4 with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 19253.58024
Subtract 1620 from 1900 to 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.

On to step 13:
405 goes into 2800 6 times with a remainder of 370.
Use 6 as the next digit of our solution. 
Result so far: 19253.580246
If we take 2430 away from 2800, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 14:
405 goes into 3700 9 times with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 19253.5802469
Deduct 3645 from 3700 and we're left 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.

On to step 15:
405 can be fit into 550 1 times, resulting in a remainder of 145.
The next digit of our result is 1. 
Result so far: 19253.58024691
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.

The final result is 19253.58024691 with a remainder of 1.45e-07.
