17992059 ÷ 345 
Let's see how many times 345 fits into 17992059.

Moving on to step 1:
When dividing 1 by 345, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 345

Let's proceed to step 2:
345 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 345

Step 3:
The number 345 fits into 179 0 times, leaving a remainder of 179.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 179, we end up with 179.
Bring next digit (9) of the dividend behind the 179 and repeat the process: 1799 / 345

Moving on to step 4:
If we divide 1799 by 345, we get 5 and a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 1725 from 1799 leaves us with 74.
Include the next digit (2) from the dividend after 74, then repeat: 742 / 345

Moving on to step 5:
742 divided by 345 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 52.0
Deduct 690 from 742 and we're left with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 345

Going ahead to step 6:
345 goes into 520 1 times with a remainder of 175.
Use 1 as the next digit of our solution. 
Result so far: 521.0
Subtract 345 from 520 to get 175.
Include the next digit (5) from the dividend after 175, then repeat: 1755 / 345

On to step 7:
The number 345 fits into 1755 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 5215.0
The remainder is 30 after subtracting 1725 from 1755.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 345

Going ahead to step 8:
If we divide 309 by 345, we get 0 and a remainder of 309.
Write down 0 as next digit of the result. 
Result so far: 52150.0
Subtracting 0 from 309 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 9:
The number 345 fits into 3090 8 times, leaving a remainder of 330.
The number 8 becomes the next digit in our result. 
Result so far: 52150.8
The remainder is 330 after subtracting 2760 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
345 goes into 3300 9 times with a remainder of 195.
Put 9 as the next digit of the answer. 
Result so far: 52150.89
If we subtract 3105 from 3300, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 11:
345 goes into 1950 5 times with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 52150.895
If we subtract 1725 from 1950, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 12:
345 can be fit into 2250 6 times, resulting in a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 52150.8956
Deduct 2070 from 2250 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
The number 345 fits into 1800 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 52150.89565
Subtracting 1725 from 1800 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 14:
750 divided by 345 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 52150.895652
If we subtract 690 from 750, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
If we divide 600 by 345, we get 1 and a remainder of 255.
Record the quotient 1 as the next digit in the result. 
Result so far: 52150.8956521
Subtract 345 from 600 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 16:
2550 divided by 345 is 7 with a remainder of 135.
The next digit of our result is 7. 
Result so far: 52150.89565217
Subtract 2415 from 2550 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 52150.89565217 with a remainder of 1.35e-07.
