We look at the division of 843145 by 68 
Let's see how many times 68 fits into 843145.

Advancing to step 1:
68 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 68

Step 2:
If we divide 84 by 68, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 68 from 84 leaves us with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 68

Step 3:
When dividing 163 by 68, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 136 from 163, we get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 68

Step 4:
The number 68 fits into 271 3 times, leaving a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
The remainder is 67 after subtracting 204 from 271.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 68

Let's proceed to step 5:
674 divided by 68 is 9 with a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 1239.0
Subtracting 612 from 674 leaves us with 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 68

Step 6:
The number 68 fits into 625 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 12399.0
If we subtract 612 from 625, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 68, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 12399.1
Subtract 68 from 130 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
When dividing 620 by 68, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 12399.19
Subtracting 612 from 620 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 9:
68 goes into 80 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 12399.191
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
68 goes into 120 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 12399.1911
If we subtract 68 from 120, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 12399.1911 with a remaining 0.00052.
