We divide 42957 by 27
We're looking to find how many times 27 goes into 42957.

Moving on to step 1:
27 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 27

Going ahead to step 2:
When dividing 42 by 27, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 27 from 42 and we're left with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 27

On to step 3:
27 goes into 159 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 135 from 159 to get 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 27

Moving on to step 4:
The number 27 fits into 245 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtract 243 from 245 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 27

On to step 5:
When dividing 27 by 27, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1591.0
Deduct 27 from 27 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 6:
27 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1591.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
27 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1591.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1591.0, with a leftover of 0.0.
