997872 ÷ 77 
We want to divide 997872 by 77.

On 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
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 77

Step 2:
77 goes into 99 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 99, we end up with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 77

Let's proceed to step 3:
If we divide 227 by 77, we get 2 and a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 154 from 227 leaves us with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 77

Step 4:
738 divided by 77 is 9 with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we subtract 693 from 738, we get 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 77

Moving on to step 5:
457 divided by 77 is 5 with a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 1295.0
Subtract 385 from 457 to get 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 77

Step 6:
When dividing 722 by 77, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 12959.0
Deduct 693 from 722 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 77, we get 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 12959.3
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.

On to step 8:
77 goes into 590 7 times with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 12959.37
The remainder is 51 after subtracting 539 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
77 goes into 510 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 12959.376
If we subtract 462 from 510, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
When dividing 480 by 77, we get 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 12959.3766
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.

Our division results in 12959.3766 with a remaining 0.00018.
