17954345 ÷ 345 
Our goal is to divide 17954345 by 345.

Going ahead to step 1:
1 divided by 345 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 345

Moving on to step 2:
If we divide 17 by 345, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 345

On to step 3:
179 divided by 345 is 0 with a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 179, we end up with 179.
Bring next digit (5) of the dividend behind the 179 and repeat the process: 1795 / 345

Going ahead to step 4:
When dividing 1795 by 345, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 70 after subtracting 1725 from 1795.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 345

Step 5:
345 can be fit into 704 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 14 after subtracting 690 from 704.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 345

Going ahead to step 6:
143 divided by 345 is 0 with a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 520.0
If we take 0 away from 143, we end up with 143.
Append the next digit (4) from the dividend to 143 and continue with: 1434 / 345

Going ahead to step 7:
If we divide 1434 by 345, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 5204.0
Deduct 1380 from 1434 and we're left with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 345

On to step 8:
345 goes into 545 1 times with a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 52041.0
If we take 345 away from 545, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 9:
If we divide 2000 by 345, we get 5 and a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 52041.5
If we take 1725 away from 2000, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 10:
If we divide 2750 by 345, we get 7 and a remainder of 335.
The number 7 becomes the next digit in our result. 
Result so far: 52041.57
Deduct 2415 from 2750 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 11:
If we divide 3350 by 345, we get 9 and a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 52041.579
If we take 3105 away from 3350, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 12:
The number 345 fits into 2450 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 52041.5797
Subtracting 2415 from 2450 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
The number 345 fits into 350 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 52041.57971
Subtract 345 from 350 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
If we divide 50 by 345, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 52041.57971
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
When dividing 500 by 345, we get 1 with a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 52041.5797101
Subtracting 345 from 500 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 16:
If we divide 1550 by 345, we get 4 and a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 52041.57971014
If we subtract 1380 from 1550, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 52041.57971014 with a remainder of 1.7e-07.
