We're dividing 25842121 by 537 
Let's see how many times 537 fits into 25842121.

Step 1:
When dividing 2 by 537, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 537

Moving on to step 2:
When dividing 25 by 537, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 537

Going ahead to step 3:
258 divided by 537 is 0 with a remainder of 258.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 258 and we're left with 258.
Take the next digit (4) from the dividend and append it to 258, then repeat: 2584 / 537

Let's proceed to step 4:
When dividing 2584 by 537, we get 4 with a remainder of 436.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2148 from 2584 and we're left with 436.
Bring next digit (2) of the dividend behind the 436 and repeat the process: 4362 / 537

Let's proceed to step 5:
4362 divided by 537 is 8 with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 4296 from 4362 leaves us with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 537

Step 6:
661 divided by 537 is 1 with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 481.0
The remainder is 124 after subtracting 537 from 661.
Fetch the next digit (2) from the dividend, attach it to 124 and continue: 1242 / 537

Moving on to step 7:
The number 537 fits into 1242 2 times, leaving a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 4812.0
The remainder is 168 after subtracting 1074 from 1242.
Take the next digit (1) from the dividend and append it to 168, then repeat: 1681 / 537

Going ahead to step 8:
537 goes into 1681 3 times with a remainder of 70.
The next digit of our result is 3. 
Result so far: 48123.0
Subtract 1611 from 1681 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
537 can be fit into 700 1 times, resulting in a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 48123.1
If we take 537 away from 700, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 10:
If we divide 1630 by 537, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 48123.13
The remainder is 19 after subtracting 1611 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
190 divided by 537 is 0 with a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 48123.13
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
537 can be fit into 1900 3 times, resulting in a remainder of 289.
The next digit of our result is 3. 
Result so far: 48123.1303
If we take 1611 away from 1900, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 13:
2890 divided by 537 is 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 48123.13035
If we subtract 2685 from 2890, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 14:
537 can be fit into 2050 3 times, resulting in a remainder of 439.
Use 3 as the next digit of our solution. 
Result so far: 48123.130353
The remainder is 439 after subtracting 1611 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 15:
537 can be fit into 4390 8 times, resulting in a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 48123.1303538
Subtracting 4296 from 4390 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 16:
When dividing 940 by 537, we get 1 with a remainder of 403.
Write down 1 as next digit of the result. 
Result so far: 48123.13035381
If we take 537 away from 940, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

The final outcome is 48123.13035381, with a leftover of 4.03e-07.
