340 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 340

Advancing to step 2:
42 divided by 340 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 340

Step 3:
340 goes into 425 1 times with a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 340 from 425 and we're left with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 340

Moving on to step 4:
340 can be fit into 851 2 times, resulting in a remainder of 171.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 680 away from 851, we end up with 171.
Fetch the next digit (3) from the dividend, attach it to 171 and continue: 1713 / 340

Advancing to step 5:
1713 divided by 340 is 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 1700 from 1713 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 340

Advancing to step 6:
340 goes into 139 0 times with a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 1250.0
Subtract 0 from 139 to get 139.
Bring next digit (7) of the dividend behind the 139 and repeat the process: 1397 / 340

Step 7:
340 can be fit into 1397 4 times, resulting in a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 12504.0
The remainder is 37 after subtracting 1360 from 1397.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 340

Moving on to step 8:
340 can be fit into 378 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 125041.0
If we subtract 340 from 378, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
The number 340 fits into 380 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 125041.1
If we subtract 340 from 380, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 340 is 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 125041.11
If we take 340 away from 400, 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.

Our division results in 125041.11 with a remaining 0.06.
