We look at the division of 53949039 by 25 
We're looking to find how many times 25 goes into 53949039.

On to step 1:
When dividing 5 by 25, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 25

Going ahead to step 2:
25 goes into 53 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 50 from 53 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 25

Step 3:
When dividing 39 by 25, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 25 from 39 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 25

On to step 4:
The number 25 fits into 144 5 times, leaving a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 215.0
If we take 125 away from 144, we end up with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 25

Advancing to step 5:
25 goes into 199 7 times with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 2157.0
Deduct 175 from 199 and we're left with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 25

Moving on to step 6:
240 divided by 25 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 21579.0
If we take 225 away from 240, we end up with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 25

Let's proceed to step 7:
153 divided by 25 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 215796.0
Deduct 150 from 153 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 25

Step 8:
25 goes into 39 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 2157961.0
If we take 25 away from 39, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
25 can be fit into 140 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 2157961.5
The remainder is 15 after subtracting 125 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
25 goes into 150 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2157961.56
Subtract 150 from 150 to get 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 11:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2157961.56
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 2157961.56
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 2157961.56, with a leftover of 0.0.
