We look at the division of 25712510 by 393 
We're looking to find how many times 393 goes into 25712510.

Advancing to step 1:
393 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 393

Moving on to step 2:
When dividing 25 by 393, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 393

Advancing to step 3:
If we divide 257 by 393, we get 0 and a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 257, we end up with 257.
Grab the next digit (1) from the dividend, add it to 257, then carry on: 2571 / 393

Moving on to step 4:
If we divide 2571 by 393, we get 6 and a remainder of 213.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 2358 from 2571 to get 213.
Append the next digit (2) from the dividend to 213 and continue with: 2132 / 393

Moving on to step 5:
393 can be fit into 2132 5 times, resulting in a remainder of 167.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtract 1965 from 2132 to get 167.
Append the next digit (5) from the dividend to 167 and continue with: 1675 / 393

Advancing to step 6:
1675 divided by 393 is 4 with a remainder of 103.
Use 4 as the next digit of our solution. 
Result so far: 654.0
Subtract 1572 from 1675 to get 103.
Grab the next digit (1) from the dividend, add it to 103, then carry on: 1031 / 393

Let's proceed to step 7:
1031 divided by 393 is 2 with a remainder of 245.
Record the quotient 2 as the next digit in the result. 
Result so far: 6542.0
Subtracting 786 from 1031 leaves us with 245.
Take the next digit (0) from the dividend and append it to 245, then repeat: 2450 / 393

Step 8:
393 goes into 2450 6 times with a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 65426.0
If we take 2358 away from 2450, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 9:
If we divide 920 by 393, we get 2 and a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 65426.2
If we take 786 away from 920, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
If we divide 1340 by 393, we get 3 and a remainder of 161.
Write down 3 as next digit of the result. 
Result so far: 65426.23
Deduct 1179 from 1340 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 11:
The number 393 fits into 1610 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 65426.234
Subtract 1572 from 1610 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 393 fits into 380 0 times, leaving a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 65426.234
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 13:
The number 393 fits into 3800 9 times, leaving a remainder of 263.
The next digit of our result is 9. 
Result so far: 65426.23409
Deduct 3537 from 3800 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 14:
2630 divided by 393 is 6 with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 65426.234096
Deduct 2358 from 2630 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 15:
2720 divided by 393 is 6 with a remainder of 362.
Record the quotient 6 as the next digit in the result. 
Result so far: 65426.2340966
The remainder is 362 after subtracting 2358 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The final outcome is 65426.2340966, with a leftover of 3.62e-06.
