We're dividing 90876030 by 257 
We're looking to find how many times 257 goes into 90876030.

Step 1:
If we divide 9 by 257, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 257

Step 2:
When dividing 90 by 257, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 257

On to step 3:
257 can be fit into 908 3 times, resulting in a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 771 away from 908, we end up with 137.
Append the next digit (7) from the dividend to 137 and continue with: 1377 / 257

Going ahead to step 4:
If we divide 1377 by 257, we get 5 and a remainder of 92.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 1285 from 1377 to get 92.
Append the next digit (6) from the dividend to 92 and continue with: 926 / 257

Advancing to step 5:
The number 257 fits into 926 3 times, leaving a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 353.0
The remainder is 155 after subtracting 771 from 926.
Grab the next digit (0) from the dividend, add it to 155, then carry on: 1550 / 257

On to step 6:
257 goes into 1550 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3536.0
The remainder is 8 after subtracting 1542 from 1550.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 257

Advancing to step 7:
If we divide 83 by 257, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 35360.0
Deduct 0 from 83 and we're left with 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 257

On to step 8:
The number 257 fits into 830 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 353603.0
Deduct 771 from 830 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
257 goes into 590 2 times with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 353603.2
Subtract 514 from 590 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
If we divide 760 by 257, we get 2 and a remainder of 246.
Put 2 as the next digit of the answer. 
Result so far: 353603.22
Subtract 514 from 760 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Our division results in 353603.22 with a remaining 0.246.
