25197131 divided by 51 
Our goal is to divide 25197131 by 51.

Let's proceed to step 1:
51 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 51

Let's proceed to step 2:
51 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 51

Going ahead to step 3:
The number 51 fits into 251 4 times, leaving a remainder of 47.
The next digit of our result is 4. 
Result so far: 4.0
If we take 204 away from 251, we end up with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 51

On to step 4:
51 can be fit into 479 9 times, resulting in a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtracting 459 from 479 leaves us with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 51

Let's proceed to step 5:
If we divide 207 by 51, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 494.0
Subtract 204 from 207 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 51

On to step 6:
The number 51 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 4940.0
If we subtract 0 from 31, we get 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 51

Step 7:
51 goes into 313 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 49406.0
If we subtract 306 from 313, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 51

On to step 8:
51 goes into 71 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 494061.0
Deduct 51 from 71 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 51, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 494061.3
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
If we divide 470 by 51, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 494061.39
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
The number 51 fits into 110 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 494061.392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 51, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 494061.3921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
When dividing 290 by 51, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 494061.39215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 494061.392156
If we take 306 away from 350, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 15:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 494061.3921568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
If we divide 320 by 51, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 494061.39215686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 494061.39215686 with a balance of 1.4e-08.
