We're dividing 57091429 by 345 
We want to divide 57091429 by 345.

Going ahead to step 1:
If we divide 5 by 345, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 345

Going ahead to step 2:
57 divided by 345 is 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 345

Advancing to step 3:
When dividing 570 by 345, we get 1 with a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 345 from 570 to get 225.
Append the next digit (9) from the dividend to 225 and continue with: 2259 / 345

Step 4:
345 goes into 2259 6 times with a remainder of 189.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 2070 from 2259 to get 189.
Append the next digit (1) from the dividend to 189 and continue with: 1891 / 345

Advancing to step 5:
When dividing 1891 by 345, we get 5 with a remainder of 166.
Put 5 as the next digit of the answer. 
Result so far: 165.0
The remainder is 166 after subtracting 1725 from 1891.
Append the next digit (4) from the dividend to 166 and continue with: 1664 / 345

Step 6:
345 goes into 1664 4 times with a remainder of 284.
The next digit of our result is 4. 
Result so far: 1654.0
Subtract 1380 from 1664 to get 284.
Include the next digit (2) from the dividend after 284, then repeat: 2842 / 345

Step 7:
The number 345 fits into 2842 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 16548.0
If we subtract 2760 from 2842, we get 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 345

Going ahead to step 8:
If we divide 829 by 345, we get 2 and a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 165482.0
Deduct 690 from 829 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 9:
345 goes into 1390 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 165482.4
The remainder is 10 after subtracting 1380 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 345, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 165482.4
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
345 goes into 1000 2 times with a remainder of 310.
Put 2 as the next digit of the answer. 
Result so far: 165482.402
Deduct 690 from 1000 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
The number 345 fits into 3100 8 times, leaving a remainder of 340.
The number 8 becomes the next digit in our result. 
Result so far: 165482.4028
If we subtract 2760 from 3100, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 13:
When dividing 3400 by 345, we get 9 with a remainder of 295.
Use 9 as the next digit of our solution. 
Result so far: 165482.40289
Subtract 3105 from 3400 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 14:
345 goes into 2950 8 times with a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 165482.402898
Subtract 2760 from 2950 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 15:
345 goes into 1900 5 times with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 165482.4028985
If we take 1725 away from 1900, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 16:
345 can be fit into 1750 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 165482.40289855
The remainder is 25 after subtracting 1725 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 165482.40289855 with a balance of 2.5e-08.
