We divide 73090638 by 256
We want to divide 73090638 by 256.

Going ahead to step 1:
256 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 256

Advancing to step 2:
The number 256 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (0) of the dividend behind the 73 and repeat the process: 730 / 256

On to step 3:
256 goes into 730 2 times with a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 512 away from 730, we end up with 218.
Bring next digit (9) of the dividend behind the 218 and repeat the process: 2189 / 256

Let's proceed to step 4:
2189 divided by 256 is 8 with a remainder of 141.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 2048 from 2189 leaves us with 141.
Grab the next digit (0) from the dividend, add it to 141, then carry on: 1410 / 256

Moving on to step 5:
256 goes into 1410 5 times with a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 285.0
The remainder is 130 after subtracting 1280 from 1410.
Include the next digit (6) from the dividend after 130, then repeat: 1306 / 256

Step 6:
If we divide 1306 by 256, we get 5 and a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 2855.0
If we take 1280 away from 1306, we end up with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 256

Let's proceed to step 7:
When dividing 263 by 256, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 28551.0
If we take 256 away from 263, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 256

On to step 8:
78 divided by 256 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 285510.0
The remainder is 78 after subtracting 0 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
If we divide 780 by 256, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 285510.3
Subtracting 768 from 780 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
256 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 285510.3
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
When dividing 1200 by 256, we get 4 with a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 285510.304
Subtracting 1024 from 1200 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 12:
1760 divided by 256 is 6 with a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 285510.3046
Subtracting 1536 from 1760 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 13:
The number 256 fits into 2240 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 285510.30468
If we subtract 2048 from 2240, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
256 can be fit into 1920 7 times, resulting in a remainder of 128.
Use 7 as the next digit of our solution. 
Result so far: 285510.304687
If we take 1792 away from 1920, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
256 can be fit into 1280 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 285510.3046875
If we take 1280 away from 1280, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
256 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 285510.3046875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 285510.3046875 and a remainder of 0.0.
