Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 408 from 778 leaves us with 370.
Grab the next digit (7) from the dividend, add it to 370, then carry on: 3707 / 408

Moving on to step 4:
The number 408 fits into 3707 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 3672 from 3707 to get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 408

On to step 5:
The number 408 fits into 358 0 times, leaving a remainder of 358.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Subtract 0 from 358 to get 358.
Bring next digit (0) of the dividend behind the 358 and repeat the process: 3580 / 408

Advancing to step 6:
408 goes into 3580 8 times with a remainder of 316.
Put 8 as the next digit of the answer. 
Result so far: 1908.0
If we subtract 3264 from 3580, we get 316.
Append the next digit (5) from the dividend to 316 and continue with: 3165 / 408

Going ahead to step 7:
The number 408 fits into 3165 7 times, leaving a remainder of 309.
Use 7 as the next digit of our solution. 
Result so far: 19087.0
Subtracting 2856 from 3165 leaves us with 309.
Append the next digit (0) from the dividend to 309 and continue with: 3090 / 408

Let's proceed to step 8:
408 goes into 3090 7 times with a remainder of 234.
Use 7 as the next digit of our solution. 
Result so far: 190877.0
Subtract 2856 from 3090 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 9:
408 goes into 2340 5 times with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 190877.5
Subtracting 2040 from 2340 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
When dividing 3000 by 408, we get 7 with a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 190877.57
Subtracting 2856 from 3000 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
The number 408 fits into 1440 3 times, leaving a remainder of 216.
Put 3 as the next digit of the answer. 
Result so far: 190877.573
If we take 1224 away from 1440, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 12:
408 goes into 2160 5 times with a remainder of 120.
The next digit of our result is 5. 
Result so far: 190877.5735
The remainder is 120 after subtracting 2040 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
1200 divided by 408 is 2 with a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 190877.57352
If we subtract 816 from 1200, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 14:
The number 408 fits into 3840 9 times, leaving a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 190877.573529
The remainder is 168 after subtracting 3672 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 15:
If we divide 1680 by 408, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 190877.5735294
If we subtract 1632 from 1680, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
The number 408 fits into 480 1 times, leaving a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 190877.57352941
Subtract 408 from 480 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 190877.57352941, with a leftover of 7.2e-08.
