Let's divide 25149620 by 801
We're looking to find how many times 801 goes into 25149620.

On to step 1:
The number 801 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 801

Step 2:
When dividing 25 by 801, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 801

Going ahead to step 3:
801 goes into 251 0 times with a remainder of 251.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 251 after subtracting 0 from 251.
Bring next digit (4) of the dividend behind the 251 and repeat the process: 2514 / 801

Going ahead to step 4:
801 can be fit into 2514 3 times, resulting in a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2403 from 2514 and we're left with 111.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 801

On to step 5:
If we divide 1119 by 801, we get 1 and a remainder of 318.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 801 from 1119, we get 318.
Include the next digit (6) from the dividend after 318, then repeat: 3186 / 801

Let's proceed to step 6:
If we divide 3186 by 801, we get 3 and a remainder of 783.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
Deduct 2403 from 3186 and we're left with 783.
Grab the next digit (2) from the dividend, add it to 783, then carry on: 7832 / 801

Step 7:
801 can be fit into 7832 9 times, resulting in a remainder of 623.
The number 9 becomes the next digit in our result. 
Result so far: 3139.0
The remainder is 623 after subtracting 7209 from 7832.
Bring next digit (0) of the dividend behind the 623 and repeat the process: 6230 / 801

Going ahead to step 8:
6230 divided by 801 is 7 with a remainder of 623.
Write down 7 as next digit of the result. 
Result so far: 31397.0
The remainder is 623 after subtracting 5607 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Moving on to step 9:
When dividing 6230 by 801, we get 7 with a remainder of 623.
Write down 7 as next digit of the result. 
Result so far: 31397.7
The remainder is 623 after subtracting 5607 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

On to step 10:
If we divide 6230 by 801, we get 7 and a remainder of 623.
Write down 7 as next digit of the result. 
Result so far: 31397.77
If we take 5607 away from 6230, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

The final result is 31397.77 with a remainder of 0.623.
