43151402 ÷ 340 
We want to figure out the number of times 43151402 can be divided by 340.

On to step 1:
4 divided by 340 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 340

Going ahead to step 2:
The number 340 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 340

Moving on to step 3:
340 goes into 431 1 times with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 340 from 431 and we're left with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 340

Step 4:
The number 340 fits into 915 2 times, leaving a remainder of 235.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 680 from 915, we get 235.
Append the next digit (1) from the dividend to 235 and continue with: 2351 / 340

On to step 5:
340 can be fit into 2351 6 times, resulting in a remainder of 311.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 2040 from 2351 to get 311.
Append the next digit (4) from the dividend to 311 and continue with: 3114 / 340

Going ahead to step 6:
340 can be fit into 3114 9 times, resulting in a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 1269.0
Deduct 3060 from 3114 and we're left with 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 340

On to step 7:
340 can be fit into 540 1 times, resulting in a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 12691.0
If we take 340 away from 540, we end up with 200.
Bring next digit (2) of the dividend behind the 200 and repeat the process: 2002 / 340

Step 8:
340 can be fit into 2002 5 times, resulting in a remainder of 302.
Put 5 as the next digit of the answer. 
Result so far: 126915.0
Deduct 1700 from 2002 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 9:
3020 divided by 340 is 8 with a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 126915.8
Subtract 2720 from 3020 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
340 can be fit into 3000 8 times, resulting in a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 126915.88
The remainder is 280 after subtracting 2720 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 126915.88 and a remainder of 0.28.
