We look at the division of 909583 by 77 
Let's see how many times 77 fits into 909583.

Going ahead to step 1:
9 divided by 77 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 77

Let's proceed to step 2:
When dividing 90 by 77, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 77 from 90.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 77

Going ahead to step 3:
The number 77 fits into 139 1 times, leaving a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 77 from 139 to get 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 77

Going ahead to step 4:
If we divide 625 by 77, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtract 616 from 625 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 77

Advancing to step 5:
77 goes into 98 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1181.0
Deduct 77 from 98 and we're left with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 77

Let's proceed to step 6:
When dividing 213 by 77, we get 2 with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 11812.0
Deduct 154 from 213 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
77 can be fit into 590 7 times, resulting in a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 11812.7
If we take 539 away from 590, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
If we divide 510 by 77, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 11812.76
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
77 can be fit into 480 6 times, resulting in a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 11812.766
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 11812.766 with a remaining 0.0018.
