We look at the division of 49989 by 77 
We want to divide 49989 by 77.

Advancing to step 1:
77 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 77

Advancing to step 2:
The number 77 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 77

Step 3:
If we divide 499 by 77, we get 6 and a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 462 from 499 to get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 77

Going ahead to step 4:
When dividing 378 by 77, we get 4 with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 70 after subtracting 308 from 378.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 77

Moving on to step 5:
77 goes into 709 9 times with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 649.0
Deduct 693 from 709 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 6:
When dividing 160 by 77, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 649.2
If we subtract 154 from 160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 77 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 649.2
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
77 can be fit into 600 7 times, resulting in a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 649.207
The remainder is 61 after subtracting 539 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
610 divided by 77 is 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 649.2077
The remainder is 71 after subtracting 539 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 649.2077 with a balance of 0.00071.
