398309 ÷ 68 
Let's see how many times 68 fits into 398309.

Let's proceed to step 1:
3 divided by 68 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 68

On to step 2:
When dividing 39 by 68, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 68

Step 3:
398 divided by 68 is 5 with a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 340 from 398 to get 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 68

Step 4:
When dividing 583 by 68, we get 8 with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 544 from 583 leaves us with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 68

Step 5:
If we divide 390 by 68, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 585.0
Deduct 340 from 390 and we're left with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 68

Step 6:
The number 68 fits into 509 7 times, leaving a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 5857.0
Subtracting 476 from 509 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
68 can be fit into 330 4 times, resulting in a remainder of 58.
The next digit of our result is 4. 
Result so far: 5857.4
Deduct 272 from 330 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
68 can be fit into 580 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 5857.48
The remainder is 36 after subtracting 544 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
The number 68 fits into 360 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 5857.485
If we subtract 340 from 360, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 68 fits into 200 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 5857.4852
If we subtract 136 from 200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
If we divide 640 by 68, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 5857.48529
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
The number 68 fits into 280 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 5857.485294
Subtracting 272 from 280 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 68 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 5857.4852941
If we take 68 away from 80, 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 14:
The number 68 fits into 120 1 times, leaving a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 5857.48529411
Subtracting 68 from 120 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 5857.48529411, with a leftover of 5.2e-08.
