43836478 divided by 345 
Let's see how many times 345 fits into 43836478.

Going ahead to step 1:
345 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 345

On to step 2:
The number 345 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 345

On to step 3:
345 can be fit into 438 1 times, resulting in a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 93 after subtracting 345 from 438.
Bring next digit (3) of the dividend behind the 93 and repeat the process: 933 / 345

Step 4:
If we divide 933 by 345, we get 2 and a remainder of 243.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 690 from 933 to get 243.
Grab the next digit (6) from the dividend, add it to 243, then carry on: 2436 / 345

Let's proceed to step 5:
If we divide 2436 by 345, we get 7 and a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtract 2415 from 2436 to get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 345

Moving on to step 6:
The number 345 fits into 214 0 times, leaving a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 1270.0
Deduct 0 from 214 and we're left with 214.
Include the next digit (7) from the dividend after 214, then repeat: 2147 / 345

Let's proceed to step 7:
The number 345 fits into 2147 6 times, leaving a remainder of 77.
The number 6 becomes the next digit in our result. 
Result so far: 12706.0
If we take 2070 away from 2147, we end up with 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 345

Going ahead to step 8:
When dividing 778 by 345, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 127062.0
If we take 690 away from 778, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 9:
345 goes into 880 2 times with a remainder of 190.
The next digit of our result is 2. 
Result so far: 127062.2
Subtracting 690 from 880 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
1900 divided by 345 is 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 127062.25
If we subtract 1725 from 1900, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 11:
1750 divided by 345 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 127062.255
Deduct 1725 from 1750 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 127062.255, with a leftover of 0.0025.
