68112990 ÷ 339 
Our goal is to divide 68112990 by 339.

Going ahead to step 1:
6 divided by 339 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 339

Step 2:
68 divided by 339 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 339

Advancing to step 3:
339 can be fit into 681 2 times, resulting in a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 678 from 681 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 339

On to step 4:
339 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 31, we end up with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 339

Moving on to step 5:
312 divided by 339 is 0 with a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 200.0
If we subtract 0 from 312, we get 312.
Bring next digit (9) of the dividend behind the 312 and repeat the process: 3129 / 339

Moving on to step 6:
339 can be fit into 3129 9 times, resulting in a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 2009.0
If we subtract 3051 from 3129, we get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 339

Moving on to step 7:
When dividing 789 by 339, we get 2 with a remainder of 111.
The number 2 becomes the next digit in our result. 
Result so far: 20092.0
The remainder is 111 after subtracting 678 from 789.
Include the next digit (0) from the dividend after 111, then repeat: 1110 / 339

Moving on to step 8:
339 can be fit into 1110 3 times, resulting in a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 200923.0
The remainder is 93 after subtracting 1017 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
When dividing 930 by 339, we get 2 with a remainder of 252.
Write down 2 as next digit of the result. 
Result so far: 200923.2
Subtract 678 from 930 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 10:
339 goes into 2520 7 times with a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 200923.27
If we subtract 2373 from 2520, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 11:
339 can be fit into 1470 4 times, resulting in a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 200923.274
If we take 1356 away from 1470, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 12:
339 goes into 1140 3 times with a remainder of 123.
The next digit of our result is 3. 
Result so far: 200923.2743
Subtract 1017 from 1140 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 13:
1230 divided by 339 is 3 with a remainder of 213.
Use 3 as the next digit of our solution. 
Result so far: 200923.27433
If we take 1017 away from 1230, we end up 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.

In conclusion, the division gives 200923.27433 with a balance of 0.000213.
