Let's divide 845904 by 77
Our goal is to divide 845904 by 77.

Step 1:
8 divided by 77 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 77

Advancing to step 2:
The number 77 fits into 84 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 77 from 84 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 77

On to step 3:
If we divide 75 by 77, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 75 to get 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 77

Advancing to step 4:
759 divided by 77 is 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtracting 693 from 759 leaves us with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 77

Moving on to step 5:
77 goes into 660 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 1098.0
If we subtract 616 from 660, we get 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 77

Moving on to step 6:
When dividing 444 by 77, we get 5 with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 10985.0
Subtract 385 from 444 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
If we divide 590 by 77, we get 7 and a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 10985.7
Subtract 539 from 590 to get 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:
When dividing 510 by 77, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 10985.76
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.

Advancing to step 9:
When dividing 480 by 77, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 10985.766
If we take 462 away from 480, we end up 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.

The final outcome is 10985.766, with a leftover of 0.0018.
