We're dividing 42734891 by 857 
We're looking to find how many times 857 goes into 42734891.

On to step 1:
857 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 857

Going ahead to step 2:
When dividing 42 by 857, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 857

Advancing to step 3:
857 goes into 427 0 times with a remainder of 427.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 427 to get 427.
Include the next digit (3) from the dividend after 427, then repeat: 4273 / 857

Going ahead to step 4:
The number 857 fits into 4273 4 times, leaving a remainder of 845.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3428 from 4273 and we're left with 845.
Grab the next digit (4) from the dividend, add it to 845, then carry on: 8454 / 857

Moving on to step 5:
857 goes into 8454 9 times with a remainder of 741.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 7713 away from 8454, we end up with 741.
Bring next digit (8) of the dividend behind the 741 and repeat the process: 7418 / 857

On to step 6:
If we divide 7418 by 857, we get 8 and a remainder of 562.
Put 8 as the next digit of the answer. 
Result so far: 498.0
Subtracting 6856 from 7418 leaves us with 562.
Fetch the next digit (9) from the dividend, attach it to 562 and continue: 5629 / 857

On to step 7:
The number 857 fits into 5629 6 times, leaving a remainder of 487.
Record the quotient 6 as the next digit in the result. 
Result so far: 4986.0
The remainder is 487 after subtracting 5142 from 5629.
Append the next digit (1) from the dividend to 487 and continue with: 4871 / 857

On to step 8:
4871 divided by 857 is 5 with a remainder of 586.
Write down 5 as next digit of the result. 
Result so far: 49865.0
Subtract 4285 from 4871 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 9:
857 can be fit into 5860 6 times, resulting in a remainder of 718.
Put 6 as the next digit of the answer. 
Result so far: 49865.6
Deduct 5142 from 5860 and we're left with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 10:
If we divide 7180 by 857, we get 8 and a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 49865.68
Deduct 6856 from 7180 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 11:
3240 divided by 857 is 3 with a remainder of 669.
Use 3 as the next digit of our solution. 
Result so far: 49865.683
If we subtract 2571 from 3240, we get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Step 12:
857 goes into 6690 7 times with a remainder of 691.
The number 7 becomes the next digit in our result. 
Result so far: 49865.6837
Deduct 5999 from 6690 and we're left with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Step 13:
When dividing 6910 by 857, we get 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 49865.68378
If we subtract 6856 from 6910, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
If we divide 540 by 857, we get 0 and a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 49865.68378
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 15:
The number 857 fits into 5400 6 times, leaving a remainder of 258.
Write down 6 as next digit of the result. 
Result so far: 49865.6837806
The remainder is 258 after subtracting 5142 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 16:
857 goes into 2580 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 49865.68378063
If we subtract 2571 from 2580, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 49865.68378063, with a leftover of 9e-09.
