9578207 ÷ 339 
Our goal is to divide 9578207 by 339.

On to step 1:
339 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 339

Advancing to step 2:
When dividing 95 by 339, we get 0 with a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 95 after subtracting 0 from 95.
Fetch the next digit (7) from the dividend, attach it to 95 and continue: 957 / 339

Advancing to step 3:
The number 339 fits into 957 2 times, leaving a remainder of 279.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 678 from 957 and we're left with 279.
Include the next digit (8) from the dividend after 279, then repeat: 2798 / 339

Going ahead to step 4:
2798 divided by 339 is 8 with a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 2712 from 2798 and we're left with 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 339

Going ahead to step 5:
When dividing 862 by 339, we get 2 with a remainder of 184.
The next digit of our result is 2. 
Result so far: 282.0
Subtract 678 from 862 to get 184.
Bring next digit (0) of the dividend behind the 184 and repeat the process: 1840 / 339

Advancing to step 6:
1840 divided by 339 is 5 with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 2825.0
If we subtract 1695 from 1840, we get 145.
Append the next digit (7) from the dividend to 145 and continue with: 1457 / 339

Step 7:
339 goes into 1457 4 times with a remainder of 101.
The number 4 becomes the next digit in our result. 
Result so far: 28254.0
If we subtract 1356 from 1457, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 8:
339 can be fit into 1010 2 times, resulting in a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 28254.2
Subtracting 678 from 1010 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 9:
3320 divided by 339 is 9 with a remainder of 269.
Record the quotient 9 as the next digit in the result. 
Result so far: 28254.29
The remainder is 269 after subtracting 3051 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 10:
The number 339 fits into 2690 7 times, leaving a remainder of 317.
Write down 7 as next digit of the result. 
Result so far: 28254.297
Deduct 2373 from 2690 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 11:
339 can be fit into 3170 9 times, resulting in a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 28254.2979
Subtract 3051 from 3170 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 12:
339 goes into 1190 3 times with a remainder of 173.
Put 3 as the next digit of the answer. 
Result so far: 28254.29793
Deduct 1017 from 1190 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 13:
339 can be fit into 1730 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 28254.297935
Deduct 1695 from 1730 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
339 goes into 350 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 28254.2979351
Subtract 339 from 350 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 15:
339 goes into 110 0 times with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 28254.2979351
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 28254.2979351 with a balance of 1.1e-07.
