We're dividing 77346354 by 339 
We're looking to find how many times 339 goes into 77346354.

Step 1:
When dividing 7 by 339, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 339

On to step 2:
339 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 339

Let's proceed to step 3:
339 goes into 773 2 times with a remainder of 95.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 678 from 773, we get 95.
Grab the next digit (4) from the dividend, add it to 95, then carry on: 954 / 339

Going ahead to step 4:
When dividing 954 by 339, we get 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 678 from 954 and we're left with 276.
Take the next digit (6) from the dividend and append it to 276, then repeat: 2766 / 339

Advancing to step 5:
The number 339 fits into 2766 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 228.0
If we subtract 2712 from 2766, we get 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 339

Moving on to step 6:
If we divide 543 by 339, we get 1 and a remainder of 204.
The next digit of our result is 1. 
Result so far: 2281.0
If we take 339 away from 543, we end up with 204.
Fetch the next digit (5) from the dividend, attach it to 204 and continue: 2045 / 339

On to step 7:
2045 divided by 339 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 22816.0
If we take 2034 away from 2045, we end up with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 339

Step 8:
When dividing 114 by 339, we get 0 with a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 228160.0
The remainder is 114 after subtracting 0 from 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 9:
If we divide 1140 by 339, we get 3 and a remainder of 123.
Use 3 as the next digit of our solution. 
Result so far: 228160.3
If we take 1017 away from 1140, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 10:
When dividing 1230 by 339, we get 3 with a remainder of 213.
Put 3 as the next digit of the answer. 
Result so far: 228160.33
Subtracting 1017 from 1230 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

The quotient of the division is 228160.33, and the remainder is 0.213.
