We look at the division of 590330 by 77 
We're looking to find how many times 77 goes into 590330.

Step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 77

Advancing to step 2:
59 divided by 77 is 0 with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Include the next digit (0) from the dividend after 59, then repeat: 590 / 77

Let's proceed to step 3:
The number 77 fits into 590 7 times, leaving a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 539 away from 590, we end up with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 77

Moving on to step 4:
77 goes into 513 6 times with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtracting 462 from 513 leaves us with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 77

Advancing to step 5:
The number 77 fits into 513 6 times, leaving a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 766.0
If we subtract 462 from 513, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 77

Let's proceed to step 6:
If we divide 510 by 77, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 7666.0
The remainder is 48 after subtracting 462 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
77 can be fit into 480 6 times, resulting in a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 7666.6
Deduct 462 from 480 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
The number 77 fits into 180 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 7666.62
Subtract 154 from 180 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
260 divided by 77 is 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 7666.623
The remainder is 29 after subtracting 231 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
If we divide 290 by 77, we get 3 and a remainder of 59.
The next digit of our result is 3. 
Result so far: 7666.6233
Deduct 231 from 290 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.

The final outcome is 7666.6233, with a leftover of 0.00059.
