39343054 ÷ 305 
We want to figure out the number of times 39343054 can be divided by 305.

Going ahead to step 1:
When dividing 3 by 305, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 305

Step 2:
When dividing 39 by 305, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 305

Moving on to step 3:
If we divide 393 by 305, we get 1 and a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 305 from 393, we get 88.
Bring next digit (4) of the dividend behind the 88 and repeat the process: 884 / 305

Let's proceed to step 4:
The number 305 fits into 884 2 times, leaving a remainder of 274.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 610 from 884 leaves us with 274.
Append the next digit (3) from the dividend to 274 and continue with: 2743 / 305

Step 5:
If we divide 2743 by 305, we get 8 and a remainder of 303.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 2440 from 2743 leaves us with 303.
Take the next digit (0) from the dividend and append it to 303, then repeat: 3030 / 305

On to step 6:
When dividing 3030 by 305, we get 9 with a remainder of 285.
Put 9 as the next digit of the answer. 
Result so far: 1289.0
Subtracting 2745 from 3030 leaves us with 285.
Grab the next digit (5) from the dividend, add it to 285, then carry on: 2855 / 305

Advancing to step 7:
The number 305 fits into 2855 9 times, leaving a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 12899.0
The remainder is 110 after subtracting 2745 from 2855.
Bring next digit (4) of the dividend behind the 110 and repeat the process: 1104 / 305

Let's proceed to step 8:
1104 divided by 305 is 3 with a remainder of 189.
Write down 3 as next digit of the result. 
Result so far: 128993.0
Subtract 915 from 1104 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 9:
When dividing 1890 by 305, we get 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 128993.6
If we take 1830 away from 1890, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 305, we get 1 with a remainder of 295.
Use 1 as the next digit of our solution. 
Result so far: 128993.61
Subtract 305 from 600 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 11:
305 goes into 2950 9 times with a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 128993.619
If we subtract 2745 from 2950, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 12:
The number 305 fits into 2050 6 times, leaving a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 128993.6196
Subtracting 1830 from 2050 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
305 goes into 2200 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 128993.61967
Subtracting 2135 from 2200 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 14:
305 can be fit into 650 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 128993.619672
If we take 610 away from 650, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
305 can be fit into 400 1 times, resulting in a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 128993.6196721
Subtracting 305 from 400 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 16:
305 can be fit into 950 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 128993.61967213
The remainder is 35 after subtracting 915 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 128993.61967213, with a leftover of 3.5e-08.
