Let's divide 998440 by 77
Our goal is to divide 998440 by 77.

Going ahead to step 1:
9 divided by 77 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 77

Let's proceed to step 2:
77 goes into 99 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 77 from 99 to get 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 77

Let's proceed to step 3:
77 can be fit into 228 2 times, resulting in a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 154 away from 228, we end up with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 77

Let's proceed to step 4:
If we divide 744 by 77, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 693 away from 744, we end up with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 77

Going ahead to step 5:
When dividing 514 by 77, we get 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 1296.0
Subtract 462 from 514 to get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 77

Step 6:
520 divided by 77 is 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 12966.0
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
The number 77 fits into 580 7 times, leaving a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 12966.7
Subtracting 539 from 580 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
When dividing 410 by 77, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12966.75
Subtracting 385 from 410 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
77 goes into 250 3 times with a remainder of 19.
The next digit of our result is 3. 
Result so far: 12966.753
Deduct 231 from 250 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
The number 77 fits into 190 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 12966.7532
Subtract 154 from 190 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 77, we get 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 12966.75324
If we subtract 308 from 360, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
If we divide 520 by 77, we get 6 and a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 12966.753246
If we take 462 away from 520, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
If we divide 580 by 77, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 12966.7532467
Subtracting 539 from 580 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 14:
77 can be fit into 410 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12966.75324675
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 12966.75324675 with a balance of 2.5e-08.
