We look at the division of 25164091 by 591 
Our goal is to divide 25164091 by 591.

Advancing to step 1:
591 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 591

Moving on to step 2:
591 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 591

Advancing to step 3:
251 divided by 591 is 0 with a remainder of 251.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 251, we get 251.
Bring next digit (6) of the dividend behind the 251 and repeat the process: 2516 / 591

Advancing to step 4:
If we divide 2516 by 591, we get 4 and a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2364 from 2516 leaves us with 152.
Append the next digit (4) from the dividend to 152 and continue with: 1524 / 591

Moving on to step 5:
If we divide 1524 by 591, we get 2 and a remainder of 342.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 1182 away from 1524, we end up with 342.
Fetch the next digit (0) from the dividend, attach it to 342 and continue: 3420 / 591

On to step 6:
When dividing 3420 by 591, we get 5 with a remainder of 465.
Use 5 as the next digit of our solution. 
Result so far: 425.0
Deduct 2955 from 3420 and we're left with 465.
Take the next digit (9) from the dividend and append it to 465, then repeat: 4659 / 591

Moving on to step 7:
591 goes into 4659 7 times with a remainder of 522.
Use 7 as the next digit of our solution. 
Result so far: 4257.0
If we take 4137 away from 4659, we end up with 522.
Grab the next digit (1) from the dividend, add it to 522, then carry on: 5221 / 591

Step 8:
5221 divided by 591 is 8 with a remainder of 493.
Put 8 as the next digit of the answer. 
Result so far: 42578.0
The remainder is 493 after subtracting 4728 from 5221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 9:
If we divide 4930 by 591, we get 8 and a remainder of 202.
The number 8 becomes the next digit in our result. 
Result so far: 42578.8
Deduct 4728 from 4930 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
The number 591 fits into 2020 3 times, leaving a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 42578.83
Subtract 1773 from 2020 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 11:
The number 591 fits into 2470 4 times, leaving a remainder of 106.
The next digit of our result is 4. 
Result so far: 42578.834
Subtract 2364 from 2470 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
591 goes into 1060 1 times with a remainder of 469.
Put 1 as the next digit of the answer. 
Result so far: 42578.8341
The remainder is 469 after subtracting 591 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Advancing to step 13:
4690 divided by 591 is 7 with a remainder of 553.
Use 7 as the next digit of our solution. 
Result so far: 42578.83417
If we take 4137 away from 4690, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 14:
If we divide 5530 by 591, we get 9 and a remainder of 211.
Put 9 as the next digit of the answer. 
Result so far: 42578.834179
The remainder is 211 after subtracting 5319 from 5530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 15:
2110 divided by 591 is 3 with a remainder of 337.
Write down 3 as next digit of the result. 
Result so far: 42578.8341793
The remainder is 337 after subtracting 1773 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 16:
591 goes into 3370 5 times with a remainder of 415.
Use 5 as the next digit of our solution. 
Result so far: 42578.83417935
If we subtract 2955 from 3370, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

The final result is 42578.83417935 with a remainder of 4.15e-07.
