42690578 divided by 857 
We want to divide 42690578 by 857.

Advancing to step 1:
When dividing 4 by 857, we get 0 with 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.
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.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 857

Moving on to step 3:
857 goes into 426 0 times with a remainder of 426.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 426 after subtracting 0 from 426.
Include the next digit (9) from the dividend after 426, then repeat: 4269 / 857

Moving on to step 4:
857 goes into 4269 4 times with a remainder of 841.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3428 from 4269 and we're left with 841.
Take the next digit (0) from the dividend and append it to 841, then repeat: 8410 / 857

Advancing to step 5:
857 goes into 8410 9 times with a remainder of 697.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 7713 from 8410 and we're left with 697.
Bring next digit (5) of the dividend behind the 697 and repeat the process: 6975 / 857

Let's proceed to step 6:
857 can be fit into 6975 8 times, resulting in a remainder of 119.
Use 8 as the next digit of our solution. 
Result so far: 498.0
If we subtract 6856 from 6975, we get 119.
Take the next digit (7) from the dividend and append it to 119, then repeat: 1197 / 857

Advancing to step 7:
857 goes into 1197 1 times with a remainder of 340.
Put 1 as the next digit of the answer. 
Result so far: 4981.0
If we take 857 away from 1197, we end up with 340.
Take the next digit (8) from the dividend and append it to 340, then repeat: 3408 / 857

On to step 8:
The number 857 fits into 3408 3 times, leaving a remainder of 837.
Record the quotient 3 as the next digit in the result. 
Result so far: 49813.0
Subtract 2571 from 3408 to get 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Let's proceed to step 9:
If we divide 8370 by 857, we get 9 and a remainder of 657.
Record the quotient 9 as the next digit in the result. 
Result so far: 49813.9
Subtracting 7713 from 8370 leaves us with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

On to step 10:
857 can be fit into 6570 7 times, resulting in a remainder of 571.
Use 7 as the next digit of our solution. 
Result so far: 49813.97
If we take 5999 away from 6570, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Step 11:
When dividing 5710 by 857, we get 6 with a remainder of 568.
The next digit of our result is 6. 
Result so far: 49813.976
Subtract 5142 from 5710 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 12:
If we divide 5680 by 857, we get 6 and a remainder of 538.
Record the quotient 6 as the next digit in the result. 
Result so far: 49813.9766
The remainder is 538 after subtracting 5142 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Our division results in 49813.9766 with a remaining 0.00538.
