We're dividing 779961 by 54 
Let's see how many times 54 fits into 779961.

Step 1:
54 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 54

Going ahead to step 2:
If we divide 77 by 54, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 54 from 77 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 54

Moving on to step 3:
If we divide 239 by 54, we get 4 and a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 216 from 239 to get 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 54

Advancing to step 4:
If we divide 239 by 54, we get 4 and a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we take 216 away from 239, we end up with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 54

Advancing to step 5:
54 goes into 236 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1444.0
Subtract 216 from 236 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 54

Moving on to step 6:
54 can be fit into 201 3 times, resulting in a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 14443.0
If we take 162 away from 201, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
If we divide 390 by 54, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 14443.7
If we take 378 away from 390, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
If we divide 120 by 54, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 14443.72
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
54 can be fit into 120 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 14443.722
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 14443.722 with a remaining 0.0012.
