25735018 ÷ 813 
Our goal is to divide 25735018 by 813.

Moving on to step 1:
813 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 813

On to step 2:
The number 813 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 813

On to step 3:
The number 813 fits into 257 0 times, leaving a remainder of 257.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 257 to get 257.
Bring next digit (3) of the dividend behind the 257 and repeat the process: 2573 / 813

Step 4:
2573 divided by 813 is 3 with a remainder of 134.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 134 after subtracting 2439 from 2573.
Bring next digit (5) of the dividend behind the 134 and repeat the process: 1345 / 813

Moving on to step 5:
1345 divided by 813 is 1 with a remainder of 532.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 813 away from 1345, we end up with 532.
Append the next digit (0) from the dividend to 532 and continue with: 5320 / 813

On to step 6:
813 goes into 5320 6 times with a remainder of 442.
Write down 6 as next digit of the result. 
Result so far: 316.0
Subtract 4878 from 5320 to get 442.
Fetch the next digit (1) from the dividend, attach it to 442 and continue: 4421 / 813

On to step 7:
When dividing 4421 by 813, we get 5 with a remainder of 356.
Use 5 as the next digit of our solution. 
Result so far: 3165.0
Subtracting 4065 from 4421 leaves us with 356.
Grab the next digit (8) from the dividend, add it to 356, then carry on: 3568 / 813

On to step 8:
813 goes into 3568 4 times with a remainder of 316.
Write down 4 as next digit of the result. 
Result so far: 31654.0
The remainder is 316 after subtracting 3252 from 3568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 9:
813 goes into 3160 3 times with a remainder of 721.
The next digit of our result is 3. 
Result so far: 31654.3
Subtracting 2439 from 3160 leaves us with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Step 10:
813 can be fit into 7210 8 times, resulting in a remainder of 706.
Use 8 as the next digit of our solution. 
Result so far: 31654.38
If we subtract 6504 from 7210, we get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

On to step 11:
7060 divided by 813 is 8 with a remainder of 556.
Record the quotient 8 as the next digit in the result. 
Result so far: 31654.388
If we take 6504 away from 7060, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

The quotient of the division is 31654.388, and the remainder is 0.0556.
