We look at the division of 77108910 by 385 
Let's see how many times 385 fits into 77108910.

Going ahead to step 1:
7 divided by 385 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 385

Going ahead to step 2:
When dividing 77 by 385, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (1) from the dividend, attach it to 77 and continue: 771 / 385

On to step 3:
385 goes into 771 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 770 from 771, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 385

Advancing to step 4:
When dividing 10 by 385, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 385

Going ahead to step 5:
When dividing 108 by 385, we get 0 with a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we subtract 0 from 108, we get 108.
Take the next digit (9) from the dividend and append it to 108, then repeat: 1089 / 385

Step 6:
If we divide 1089 by 385, we get 2 and a remainder of 319.
Put 2 as the next digit of the answer. 
Result so far: 2002.0
Subtract 770 from 1089 to get 319.
Include the next digit (1) from the dividend after 319, then repeat: 3191 / 385

Going ahead to step 7:
If we divide 3191 by 385, we get 8 and a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 20028.0
Deduct 3080 from 3191 and we're left with 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 385

Moving on to step 8:
When dividing 1110 by 385, we get 2 with a remainder of 340.
Record the quotient 2 as the next digit in the result. 
Result so far: 200282.0
If we take 770 away from 1110, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 9:
3400 divided by 385 is 8 with a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 200282.8
Subtract 3080 from 3400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
3200 divided by 385 is 8 with a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 200282.88
If we subtract 3080 from 3200, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 200282.88, with a leftover of 0.12.
