Let's divide 49458303 by 345
Let's see how many times 345 fits into 49458303.

Step 1:
If we divide 4 by 345, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 345

Moving on to step 2:
345 goes into 49 0 times with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 345

On to step 3:
If we divide 494 by 345, we get 1 and a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 345 from 494 leaves us with 149.
Bring next digit (5) of the dividend behind the 149 and repeat the process: 1495 / 345

On to step 4:
When dividing 1495 by 345, we get 4 with a remainder of 115.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 1380 from 1495 leaves us with 115.
Take the next digit (8) from the dividend and append it to 115, then repeat: 1158 / 345

Advancing to step 5:
If we divide 1158 by 345, we get 3 and a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
Subtract 1035 from 1158 to get 123.
Include the next digit (3) from the dividend after 123, then repeat: 1233 / 345

Moving on to step 6:
345 can be fit into 1233 3 times, resulting in a remainder of 198.
Use 3 as the next digit of our solution. 
Result so far: 1433.0
Subtract 1035 from 1233 to get 198.
Include the next digit (0) from the dividend after 198, then repeat: 1980 / 345

Moving on to step 7:
If we divide 1980 by 345, we get 5 and a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 14335.0
If we take 1725 away from 1980, we end up with 255.
Grab the next digit (3) from the dividend, add it to 255, then carry on: 2553 / 345

Step 8:
2553 divided by 345 is 7 with a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 143357.0
If we take 2415 away from 2553, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
345 can be fit into 1380 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 143357.4
If we take 1380 away from 1380, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
345 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 143357.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
345 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 143357.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 143357.4 with a remaining 0.0.
