We look at the division of 57234304 by 857 
We're looking to find how many times 857 goes into 57234304.

Advancing to step 1:
857 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 857

Moving on to step 2:
857 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 857

Going ahead to step 3:
857 goes into 572 0 times with a remainder of 572.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 572, we end up with 572.
Include the next digit (3) from the dividend after 572, then repeat: 5723 / 857

Let's proceed to step 4:
If we divide 5723 by 857, we get 6 and a remainder of 581.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5142 from 5723 leaves us with 581.
Include the next digit (4) from the dividend after 581, then repeat: 5814 / 857

Moving on to step 5:
857 goes into 5814 6 times with a remainder of 672.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 672 after subtracting 5142 from 5814.
Fetch the next digit (3) from the dividend, attach it to 672 and continue: 6723 / 857

Advancing to step 6:
If we divide 6723 by 857, we get 7 and a remainder of 724.
The next digit of our result is 7. 
Result so far: 667.0
The remainder is 724 after subtracting 5999 from 6723.
Take the next digit (0) from the dividend and append it to 724, then repeat: 7240 / 857

Moving on to step 7:
If we divide 7240 by 857, we get 8 and a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 6678.0
Subtract 6856 from 7240 to get 384.
Fetch the next digit (4) from the dividend, attach it to 384 and continue: 3844 / 857

Let's proceed to step 8:
When dividing 3844 by 857, we get 4 with a remainder of 416.
Write down 4 as next digit of the result. 
Result so far: 66784.0
Deduct 3428 from 3844 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 9:
When dividing 4160 by 857, we get 4 with a remainder of 732.
The next digit of our result is 4. 
Result so far: 66784.4
If we take 3428 away from 4160, we end up with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Going ahead to step 10:
The number 857 fits into 7320 8 times, leaving a remainder of 464.
The next digit of our result is 8. 
Result so far: 66784.48
The remainder is 464 after subtracting 6856 from 7320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 11:
857 goes into 4640 5 times with a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 66784.485
Deduct 4285 from 4640 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 12:
When dividing 3550 by 857, we get 4 with a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 66784.4854
If we take 3428 away from 3550, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 13:
The number 857 fits into 1220 1 times, leaving a remainder of 363.
Record the quotient 1 as the next digit in the result. 
Result so far: 66784.48541
Deduct 857 from 1220 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 14:
When dividing 3630 by 857, we get 4 with a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 66784.485414
Subtracting 3428 from 3630 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 15:
The number 857 fits into 2020 2 times, leaving a remainder of 306.
The next digit of our result is 2. 
Result so far: 66784.4854142
The remainder is 306 after subtracting 1714 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 16:
857 can be fit into 3060 3 times, resulting in a remainder of 489.
Use 3 as the next digit of our solution. 
Result so far: 66784.48541423
Subtract 2571 from 3060 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

The final outcome is 66784.48541423, with a leftover of 4.89e-07.
