We look at the division of 25131431 by 786 
We're looking to find how many times 786 goes into 25131431.

Step 1:
The number 786 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 786

Going ahead to step 2:
When dividing 25 by 786, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 786

On to step 3:
If we divide 251 by 786, we get 0 and a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 251 to get 251.
Append the next digit (3) from the dividend to 251 and continue with: 2513 / 786

Going ahead to step 4:
2513 divided by 786 is 3 with a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2358 from 2513 and we're left with 155.
Bring next digit (1) of the dividend behind the 155 and repeat the process: 1551 / 786

On to step 5:
The number 786 fits into 1551 1 times, leaving a remainder of 765.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 765 after subtracting 786 from 1551.
Take the next digit (4) from the dividend and append it to 765, then repeat: 7654 / 786

Advancing to step 6:
786 can be fit into 7654 9 times, resulting in a remainder of 580.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
If we take 7074 away from 7654, we end up with 580.
Grab the next digit (3) from the dividend, add it to 580, then carry on: 5803 / 786

Going ahead to step 7:
5803 divided by 786 is 7 with a remainder of 301.
The number 7 becomes the next digit in our result. 
Result so far: 3197.0
Subtract 5502 from 5803 to get 301.
Take the next digit (1) from the dividend and append it to 301, then repeat: 3011 / 786

Step 8:
When dividing 3011 by 786, we get 3 with a remainder of 653.
The next digit of our result is 3. 
Result so far: 31973.0
If we take 2358 away from 3011, we end up with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Let's proceed to step 9:
The number 786 fits into 6530 8 times, leaving a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 31973.8
The remainder is 242 after subtracting 6288 from 6530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 10:
786 goes into 2420 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 31973.83
Subtract 2358 from 2420 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
If we divide 620 by 786, we get 0 and a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 31973.83
If we take 0 away from 620, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 12:
If we divide 6200 by 786, we get 7 and a remainder of 698.
Use 7 as the next digit of our solution. 
Result so far: 31973.8307
Deduct 5502 from 6200 and we're left with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 13:
786 goes into 6980 8 times with a remainder of 692.
Record the quotient 8 as the next digit in the result. 
Result so far: 31973.83078
The remainder is 692 after subtracting 6288 from 6980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Going ahead to step 14:
786 goes into 6920 8 times with a remainder of 632.
Put 8 as the next digit of the answer. 
Result so far: 31973.830788
Deduct 6288 from 6920 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

The final outcome is 31973.830788, with a leftover of 6.32e-05.
