We look at the division of 80718394 by 340 
We want to divide 80718394 by 340.

On to step 1:
The number 340 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 340

Advancing to step 2:
80 divided by 340 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (7) from the dividend after 80, then repeat: 807 / 340

Let's proceed to step 3:
340 can be fit into 807 2 times, resulting in a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 680 away from 807, we end up with 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 340

Step 4:
340 goes into 1271 3 times with a remainder of 251.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 1020 away from 1271, we end up with 251.
Take the next digit (8) from the dividend and append it to 251, then repeat: 2518 / 340

Step 5:
340 can be fit into 2518 7 times, resulting in a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
Deduct 2380 from 2518 and we're left with 138.
Append the next digit (3) from the dividend to 138 and continue with: 1383 / 340

Moving on to step 6:
340 can be fit into 1383 4 times, resulting in a remainder of 23.
The next digit of our result is 4. 
Result so far: 2374.0
If we take 1360 away from 1383, we end up with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 340

Moving on to step 7:
If we divide 239 by 340, we get 0 and a remainder of 239.
Record the quotient 0 as the next digit in the result. 
Result so far: 23740.0
Subtract 0 from 239 to get 239.
Include the next digit (4) from the dividend after 239, then repeat: 2394 / 340

Advancing to step 8:
340 goes into 2394 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 237407.0
If we subtract 2380 from 2394, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 340 is 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 237407.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
340 goes into 1400 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 237407.04
The remainder is 40 after subtracting 1360 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 340 fits into 400 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 237407.041
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
If we divide 600 by 340, we get 1 and a remainder of 260.
Use 1 as the next digit of our solution. 
Result so far: 237407.0411
The remainder is 260 after subtracting 340 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 237407.0411 and a remainder of 0.0026.
