We're dividing 9570046 by 257 
We want to divide 9570046 by 257.

On to step 1:
257 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 257

Advancing to step 2:
The number 257 fits into 95 0 times, leaving a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 95 and we're left with 95.
Bring next digit (7) of the dividend behind the 95 and repeat the process: 957 / 257

Moving on to step 3:
When dividing 957 by 257, we get 3 with a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 771 away from 957, we end up with 186.
Take the next digit (0) from the dividend and append it to 186, then repeat: 1860 / 257

Moving on to step 4:
The number 257 fits into 1860 7 times, leaving a remainder of 61.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 1799 from 1860 leaves us with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 257

Step 5:
257 can be fit into 610 2 times, resulting in a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 372.0
Subtract 514 from 610 to get 96.
Take the next digit (4) from the dividend and append it to 96, then repeat: 964 / 257

Let's proceed to step 6:
If we divide 964 by 257, we get 3 and a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 3723.0
Subtracting 771 from 964 leaves us with 193.
Include the next digit (6) from the dividend after 193, then repeat: 1936 / 257

Going ahead to step 7:
The number 257 fits into 1936 7 times, leaving a remainder of 137.
Record the quotient 7 as the next digit in the result. 
Result so far: 37237.0
If we subtract 1799 from 1936, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 8:
257 can be fit into 1370 5 times, resulting in a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 37237.5
Subtracting 1285 from 1370 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
850 divided by 257 is 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 37237.53
If we take 771 away from 850, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 10:
The number 257 fits into 790 3 times, leaving a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 37237.533
Subtract 771 from 790 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 37237.533 and a remainder of 0.0019.
