257729 divided by 42 
We're looking to find how many times 42 goes into 257729.

Going ahead to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 42

Step 2:
25 divided by 42 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 42

Going ahead to step 3:
257 divided by 42 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 252 from 257 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 42

Going ahead to step 4:
42 goes into 57 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we subtract 42 from 57, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 42

On to step 5:
If we divide 152 by 42, we get 3 and a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 613.0
The remainder is 26 after subtracting 126 from 152.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 42

Step 6:
42 can be fit into 269 6 times, resulting in a remainder of 17.
The next digit of our result is 6. 
Result so far: 6136.0
If we subtract 252 from 269, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
When dividing 170 by 42, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 6136.4
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6136.4
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
42 goes into 200 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 6136.404
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 6136.4047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
When dividing 260 by 42, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6136.40476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 6136.404761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
The number 42 fits into 380 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 6136.4047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6136.4047619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 6136.4047619, with a leftover of 2e-08.
