We're dividing 25946145 by 899 
We want to figure out the number of times 25946145 can be divided by 899.

On to step 1:
899 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 899

Step 2:
If we divide 25 by 899, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 899

Advancing to step 3:
259 divided by 899 is 0 with a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 259, we get 259.
Fetch the next digit (4) from the dividend, attach it to 259 and continue: 2594 / 899

Going ahead to step 4:
899 can be fit into 2594 2 times, resulting in a remainder of 796.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1798 from 2594 and we're left with 796.
Bring next digit (6) of the dividend behind the 796 and repeat the process: 7966 / 899

On to step 5:
When dividing 7966 by 899, we get 8 with a remainder of 774.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 7192 away from 7966, we end up with 774.
Fetch the next digit (1) from the dividend, attach it to 774 and continue: 7741 / 899

On to step 6:
The number 899 fits into 7741 8 times, leaving a remainder of 549.
The next digit of our result is 8. 
Result so far: 288.0
If we take 7192 away from 7741, we end up with 549.
Bring next digit (4) of the dividend behind the 549 and repeat the process: 5494 / 899

Advancing to step 7:
899 can be fit into 5494 6 times, resulting in a remainder of 100.
The next digit of our result is 6. 
Result so far: 2886.0
Subtract 5394 from 5494 to get 100.
Include the next digit (5) from the dividend after 100, then repeat: 1005 / 899

Step 8:
The number 899 fits into 1005 1 times, leaving a remainder of 106.
The next digit of our result is 1. 
Result so far: 28861.0
Subtracting 899 from 1005 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 9:
1060 divided by 899 is 1 with a remainder of 161.
The next digit of our result is 1. 
Result so far: 28861.1
Subtract 899 from 1060 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 10:
899 can be fit into 1610 1 times, resulting in a remainder of 711.
Record the quotient 1 as the next digit in the result. 
Result so far: 28861.11
If we take 899 away from 1610, we end up with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

The final outcome is 28861.11, with a leftover of 0.711.
