51880366 divided by 345 
We're looking to find how many times 345 goes into 51880366.

Moving on to step 1:
5 divided by 345 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 345

Moving on to step 2:
345 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 345

Moving on to step 3:
345 can be fit into 518 1 times, resulting in a remainder of 173.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 345 from 518 and we're left with 173.
Append the next digit (8) from the dividend to 173 and continue with: 1738 / 345

Moving on to step 4:
The number 345 fits into 1738 5 times, leaving a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 1725 from 1738 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 345

Step 5:
345 goes into 130 0 times with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 130, we end up with 130.
Append the next digit (3) from the dividend to 130 and continue with: 1303 / 345

Moving on to step 6:
345 goes into 1303 3 times with a remainder of 268.
The number 3 becomes the next digit in our result. 
Result so far: 1503.0
If we subtract 1035 from 1303, we get 268.
Grab the next digit (6) from the dividend, add it to 268, then carry on: 2686 / 345

On to step 7:
345 can be fit into 2686 7 times, resulting in a remainder of 271.
Record the quotient 7 as the next digit in the result. 
Result so far: 15037.0
Subtract 2415 from 2686 to get 271.
Append the next digit (6) from the dividend to 271 and continue with: 2716 / 345

Moving on to step 8:
345 can be fit into 2716 7 times, resulting in a remainder of 301.
Put 7 as the next digit of the answer. 
Result so far: 150377.0
Subtracting 2415 from 2716 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 9:
345 goes into 3010 8 times with a remainder of 250.
The next digit of our result is 8. 
Result so far: 150377.8
If we subtract 2760 from 3010, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
When dividing 2500 by 345, we get 7 with a remainder of 85.
Write down 7 as next digit of the result. 
Result so far: 150377.87
If we subtract 2415 from 2500, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
345 can be fit into 850 2 times, resulting in a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 150377.872
Subtracting 690 from 850 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
If we divide 1600 by 345, we get 4 and a remainder of 220.
The number 4 becomes the next digit in our result. 
Result so far: 150377.8724
If we subtract 1380 from 1600, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 13:
345 goes into 2200 6 times with a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 150377.87246
Subtract 2070 from 2200 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
345 can be fit into 1300 3 times, resulting in a remainder of 265.
The number 3 becomes the next digit in our result. 
Result so far: 150377.872463
Subtracting 1035 from 1300 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 15:
2650 divided by 345 is 7 with a remainder of 235.
The number 7 becomes the next digit in our result. 
Result so far: 150377.8724637
Subtracting 2415 from 2650 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 16:
The number 345 fits into 2350 6 times, leaving a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 150377.87246376
If we subtract 2070 from 2350, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Our division results in 150377.87246376 with a remaining 2.8e-07.
