We look at the division of 15825973 by 631 
Our goal is to divide 15825973 by 631.

Step 1:
The number 631 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 631

Step 2:
631 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 631

Step 3:
631 can be fit into 158 0 times, resulting in a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 158 and we're left with 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 631

On to step 4:
631 goes into 1582 2 times with a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1262 from 1582 and we're left with 320.
Bring next digit (5) of the dividend behind the 320 and repeat the process: 3205 / 631

Moving on to step 5:
When dividing 3205 by 631, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 3155 from 3205, we get 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 631

Step 6:
The number 631 fits into 509 0 times, leaving a remainder of 509.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
The remainder is 509 after subtracting 0 from 509.
Take the next digit (7) from the dividend and append it to 509, then repeat: 5097 / 631

Advancing to step 7:
5097 divided by 631 is 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 2508.0
Subtracting 5048 from 5097 leaves us with 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 631

Let's proceed to step 8:
If we divide 493 by 631, we get 0 and a remainder of 493.
Use 0 as the next digit of our solution. 
Result so far: 25080.0
Subtracting 0 from 493 leaves us with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Step 9:
631 can be fit into 4930 7 times, resulting in a remainder of 513.
Use 7 as the next digit of our solution. 
Result so far: 25080.7
The remainder is 513 after subtracting 4417 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Step 10:
5130 divided by 631 is 8 with a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 25080.78
If we take 5048 away from 5130, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 11:
The number 631 fits into 820 1 times, leaving a remainder of 189.
The next digit of our result is 1. 
Result so far: 25080.781
If we subtract 631 from 820, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 12:
When dividing 1890 by 631, we get 2 with a remainder of 628.
The number 2 becomes the next digit in our result. 
Result so far: 25080.7812
Subtracting 1262 from 1890 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 13:
631 can be fit into 6280 9 times, resulting in a remainder of 601.
The next digit of our result is 9. 
Result so far: 25080.78129
The remainder is 601 after subtracting 5679 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 14:
If we divide 6010 by 631, we get 9 and a remainder of 331.
The next digit of our result is 9. 
Result so far: 25080.781299
If we subtract 5679 from 6010, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The final outcome is 25080.781299, with a leftover of 3.31e-05.
