We're dividing 7766278 by 846 
We're looking to find how many times 846 goes into 7766278.

Step 1:
If we divide 7 by 846, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 846

Let's proceed to step 2:
846 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 846

On to step 3:
The number 846 fits into 776 0 times, leaving a remainder of 776.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 776, we get 776.
Grab the next digit (6) from the dividend, add it to 776, then carry on: 7766 / 846

On to step 4:
7766 divided by 846 is 9 with a remainder of 152.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7614 from 7766 to get 152.
Include the next digit (2) from the dividend after 152, then repeat: 1522 / 846

Going ahead to step 5:
The number 846 fits into 1522 1 times, leaving a remainder of 676.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 846 from 1522 leaves us with 676.
Fetch the next digit (7) from the dividend, attach it to 676 and continue: 6767 / 846

Moving on to step 6:
If we divide 6767 by 846, we get 7 and a remainder of 845.
Use 7 as the next digit of our solution. 
Result so far: 917.0
Deduct 5922 from 6767 and we're left with 845.
Append the next digit (8) from the dividend to 845 and continue with: 8458 / 846

Advancing to step 7:
The number 846 fits into 8458 9 times, leaving a remainder of 844.
The next digit of our result is 9. 
Result so far: 9179.0
The remainder is 844 after subtracting 7614 from 8458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

On to step 8:
846 can be fit into 8440 9 times, resulting in a remainder of 826.
Write down 9 as next digit of the result. 
Result so far: 9179.9
If we take 7614 away from 8440, we end up with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Let's proceed to step 9:
When dividing 8260 by 846, we get 9 with a remainder of 646.
Record the quotient 9 as the next digit in the result. 
Result so far: 9179.99
Subtracting 7614 from 8260 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

After the division, we end up with 9179.99 and a remainder of 0.646.
