We're dividing 15867825 by 637 
Our goal is to divide 15867825 by 637.

Moving on to step 1:
637 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 637

Step 2:
If we divide 15 by 637, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 637

On to step 3:
When dividing 158 by 637, we get 0 with a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 158 leaves us with 158.
Fetch the next digit (6) from the dividend, attach it to 158 and continue: 1586 / 637

Advancing to step 4:
637 can be fit into 1586 2 times, resulting in a remainder of 312.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1274 from 1586 and we're left with 312.
Bring next digit (7) of the dividend behind the 312 and repeat the process: 3127 / 637

Going ahead to step 5:
The number 637 fits into 3127 4 times, leaving a remainder of 579.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 2548 from 3127 to get 579.
Include the next digit (8) from the dividend after 579, then repeat: 5798 / 637

Let's proceed to step 6:
637 can be fit into 5798 9 times, resulting in a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 249.0
The remainder is 65 after subtracting 5733 from 5798.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 637

Moving on to step 7:
When dividing 652 by 637, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 2491.0
Subtracting 637 from 652 leaves us with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 637

Step 8:
637 can be fit into 155 0 times, resulting in a remainder of 155.
Use 0 as the next digit of our solution. 
Result so far: 24910.0
Subtracting 0 from 155 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 9:
The number 637 fits into 1550 2 times, leaving a remainder of 276.
The next digit of our result is 2. 
Result so far: 24910.2
If we take 1274 away from 1550, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 10:
When dividing 2760 by 637, we get 4 with a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 24910.24
Subtracting 2548 from 2760 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 11:
The number 637 fits into 2120 3 times, leaving a remainder of 209.
Use 3 as the next digit of our solution. 
Result so far: 24910.243
The remainder is 209 after subtracting 1911 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 12:
The number 637 fits into 2090 3 times, leaving a remainder of 179.
Put 3 as the next digit of the answer. 
Result so far: 24910.2433
Subtracting 1911 from 2090 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

After the division, we end up with 24910.2433 and a remainder of 0.00179.
