342309 ÷ 57 
We want to figure out the number of times 342309 can be divided by 57.

Let's proceed to step 1:
57 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 57

Going ahead to step 2:
When dividing 34 by 57, we get 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 57

Moving on to step 3:
If we divide 342 by 57, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 342 away from 342, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 57

Moving on to step 4:
57 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 57

Advancing to step 5:
The number 57 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 600.0
If we subtract 0 from 30, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 57

Step 6:
57 goes into 309 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 6005.0
If we take 285 away from 309, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
240 divided by 57 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 6005.4
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
57 can be fit into 120 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 6005.42
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 57, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 6005.421
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
When dividing 30 by 57, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6005.421
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
57 can be fit into 300 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6005.42105
Subtract 285 from 300 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
When dividing 150 by 57, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 6005.421052
Deduct 114 from 150 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 57, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 6005.4210526
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
180 divided by 57 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 6005.42105263
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 6005.42105263 with a balance of 9e-09.
