49213750 ÷ 345 
We want to divide 49213750 by 345.

Moving on to step 1:
The number 345 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 345

Advancing to step 2:
The number 345 fits into 49 0 times, leaving a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 345

Going ahead to step 3:
If we divide 492 by 345, we get 1 and a remainder of 147.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 345 from 492, we get 147.
Take the next digit (1) from the dividend and append it to 147, then repeat: 1471 / 345

Let's proceed to step 4:
When dividing 1471 by 345, we get 4 with a remainder of 91.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 1380 from 1471, we get 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 345

Moving on to step 5:
345 goes into 913 2 times with a remainder of 223.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
Subtract 690 from 913 to get 223.
Include the next digit (7) from the dividend after 223, then repeat: 2237 / 345

Moving on to step 6:
345 goes into 2237 6 times with a remainder of 167.
The next digit of our result is 6. 
Result so far: 1426.0
Subtract 2070 from 2237 to get 167.
Append the next digit (5) from the dividend to 167 and continue with: 1675 / 345

Let's proceed to step 7:
1675 divided by 345 is 4 with a remainder of 295.
The next digit of our result is 4. 
Result so far: 14264.0
Deduct 1380 from 1675 and we're left with 295.
Bring next digit (0) of the dividend behind the 295 and repeat the process: 2950 / 345

Moving on to step 8:
The number 345 fits into 2950 8 times, leaving a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 142648.0
Deduct 2760 from 2950 and we're left 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.

Step 9:
1900 divided by 345 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 142648.5
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.

Going ahead to step 10:
When dividing 1750 by 345, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 142648.55
If we take 1725 away from 1750, we end up 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 142648.55, with a leftover of 0.025.
