We look at the division of 15819496 by 653 
Let's see how many times 653 fits into 15819496.

Step 1:
The number 653 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 653

Moving on to step 2:
15 divided by 653 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 653

On to step 3:
The number 653 fits into 158 0 times, leaving a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 158 and we're left with 158.
Append the next digit (1) from the dividend to 158 and continue with: 1581 / 653

Going ahead to step 4:
653 can be fit into 1581 2 times, resulting in a remainder of 275.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1306 from 1581 and we're left with 275.
Bring next digit (9) of the dividend behind the 275 and repeat the process: 2759 / 653

Let's proceed to step 5:
If we divide 2759 by 653, we get 4 and a remainder of 147.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 2612 from 2759 and we're left with 147.
Fetch the next digit (4) from the dividend, attach it to 147 and continue: 1474 / 653

Advancing to step 6:
653 goes into 1474 2 times with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 242.0
If we take 1306 away from 1474, we end up with 168.
Fetch the next digit (9) from the dividend, attach it to 168 and continue: 1689 / 653

Going ahead to step 7:
653 goes into 1689 2 times with a remainder of 383.
The next digit of our result is 2. 
Result so far: 2422.0
Subtract 1306 from 1689 to get 383.
Grab the next digit (6) from the dividend, add it to 383, then carry on: 3836 / 653

On to step 8:
When dividing 3836 by 653, we get 5 with a remainder of 571.
The next digit of our result is 5. 
Result so far: 24225.0
If we take 3265 away from 3836, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 9:
653 goes into 5710 8 times with a remainder of 486.
Record the quotient 8 as the next digit in the result. 
Result so far: 24225.8
The remainder is 486 after subtracting 5224 from 5710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 10:
653 can be fit into 4860 7 times, resulting in a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 24225.87
Deduct 4571 from 4860 and we're left 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.

On to step 11:
653 can be fit into 2890 4 times, resulting in a remainder of 278.
Record the quotient 4 as the next digit in the result. 
Result so far: 24225.874
If we subtract 2612 from 2890, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 12:
2780 divided by 653 is 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 24225.8744
Subtracting 2612 from 2780 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 24225.8744 with a remainder of 0.00168.
