We look at the division of 340830 by 71 
We're looking to find how many times 71 goes into 340830.

Step 1:
The number 71 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 71

Step 2:
If we divide 34 by 71, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 71

Moving on to step 3:
71 goes into 340 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 4.0
If we take 284 away from 340, we end up with 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 71

Moving on to step 4:
The number 71 fits into 568 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 48.0
If we take 568 away from 568, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 71

Let's proceed to step 5:
71 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 480.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 71

Step 6:
71 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4800.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
If we divide 300 by 71, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 4800.4
Subtract 284 from 300 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 71 fits into 160 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 4800.42
Deduct 142 from 160 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
When dividing 180 by 71, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 4800.422
Deduct 142 from 180 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 4800.422 with a remaining 0.0038.
