77888107 ÷ 408 
We're looking to find how many times 408 goes into 77888107.

On to step 1:
7 divided by 408 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 408

Step 2:
408 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 408

On to step 3:
408 can be fit into 778 1 times, resulting in a remainder of 370.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 370 after subtracting 408 from 778.
Fetch the next digit (8) from the dividend, attach it to 370 and continue: 3708 / 408

Going ahead to step 4:
The number 408 fits into 3708 9 times, leaving a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 3672 from 3708 to get 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 408

Let's proceed to step 5:
When dividing 368 by 408, we get 0 with a remainder of 368.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
The remainder is 368 after subtracting 0 from 368.
Append the next digit (1) from the dividend to 368 and continue with: 3681 / 408

Let's proceed to step 6:
When dividing 3681 by 408, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 1909.0
If we subtract 3672 from 3681, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 408

Let's proceed to step 7:
The number 408 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 19090.0
If we subtract 0 from 90, we get 90.
Grab the next digit (7) from the dividend, add it to 90, then carry on: 907 / 408

Let's proceed to step 8:
408 can be fit into 907 2 times, resulting in a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 190902.0
Subtracting 816 from 907 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 9:
408 goes into 910 2 times with a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 190902.2
If we subtract 816 from 910, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
If we divide 940 by 408, we get 2 and a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 190902.22
Subtracting 816 from 940 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The quotient of the division is 190902.22, and the remainder is 0.124.
