Let's divide 25135210 by 517
We want to divide 25135210 by 517.

Advancing to step 1:
The number 517 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 subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 517

Let's proceed to step 2:
25 divided by 517 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 517

Moving on to step 3:
The number 517 fits into 251 0 times, leaving a remainder of 251.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 251 leaves us with 251.
Grab the next digit (3) from the dividend, add it to 251, then carry on: 2513 / 517

Moving on to step 4:
517 can be fit into 2513 4 times, resulting in a remainder of 445.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 445 after subtracting 2068 from 2513.
Include the next digit (5) from the dividend after 445, then repeat: 4455 / 517

Going ahead to step 5:
If we divide 4455 by 517, we get 8 and a remainder of 319.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we subtract 4136 from 4455, we get 319.
Include the next digit (2) from the dividend after 319, then repeat: 3192 / 517

Step 6:
3192 divided by 517 is 6 with a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 486.0
Subtracting 3102 from 3192 leaves us with 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 517

Moving on to step 7:
517 can be fit into 901 1 times, resulting in a remainder of 384.
The number 1 becomes the next digit in our result. 
Result so far: 4861.0
Subtracting 517 from 901 leaves us with 384.
Include the next digit (0) from the dividend after 384, then repeat: 3840 / 517

Let's proceed to step 8:
3840 divided by 517 is 7 with a remainder of 221.
The next digit of our result is 7. 
Result so far: 48617.0
If we subtract 3619 from 3840, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 9:
When dividing 2210 by 517, we get 4 with a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 48617.4
Subtracting 2068 from 2210 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 10:
When dividing 1420 by 517, we get 2 with a remainder of 386.
Write down 2 as next digit of the result. 
Result so far: 48617.42
Deduct 1034 from 1420 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 11:
517 goes into 3860 7 times with a remainder of 241.
Use 7 as the next digit of our solution. 
Result so far: 48617.427
If we subtract 3619 from 3860, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 12:
2410 divided by 517 is 4 with a remainder of 342.
Write down 4 as next digit of the result. 
Result so far: 48617.4274
If we subtract 2068 from 2410, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 13:
517 goes into 3420 6 times with a remainder of 318.
The next digit of our result is 6. 
Result so far: 48617.42746
If we take 3102 away from 3420, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 14:
If we divide 3180 by 517, we get 6 and a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 48617.427466
Deduct 3102 from 3180 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 48617.427466 with a remainder of 7.8e-06.
