We look at the division of 15459915 by 703 
We're looking to find how many times 703 goes into 15459915.

Advancing to step 1:
1 divided by 703 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 703

Going ahead to step 2:
If we divide 15 by 703, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 703

Step 3:
If we divide 154 by 703, we get 0 and a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 154, we get 154.
Include the next digit (5) from the dividend after 154, then repeat: 1545 / 703

Advancing to step 4:
703 goes into 1545 2 times with a remainder of 139.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1406 from 1545, we get 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 703

Let's proceed to step 5:
703 goes into 1399 1 times with a remainder of 696.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 703 from 1399 to get 696.
Take the next digit (9) from the dividend and append it to 696, then repeat: 6969 / 703

Step 6:
When dividing 6969 by 703, we get 9 with a remainder of 642.
Put 9 as the next digit of the answer. 
Result so far: 219.0
The remainder is 642 after subtracting 6327 from 6969.
Take the next digit (1) from the dividend and append it to 642, then repeat: 6421 / 703

Moving on to step 7:
6421 divided by 703 is 9 with a remainder of 94.
Put 9 as the next digit of the answer. 
Result so far: 2199.0
If we take 6327 away from 6421, we end up with 94.
Bring next digit (5) of the dividend behind the 94 and repeat the process: 945 / 703

Step 8:
The number 703 fits into 945 1 times, leaving a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 21991.0
Deduct 703 from 945 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 9:
When dividing 2420 by 703, we get 3 with a remainder of 311.
Put 3 as the next digit of the answer. 
Result so far: 21991.3
If we take 2109 away from 2420, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 10:
The number 703 fits into 3110 4 times, leaving a remainder of 298.
Put 4 as the next digit of the answer. 
Result so far: 21991.34
Deduct 2812 from 3110 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 11:
The number 703 fits into 2980 4 times, leaving a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 21991.344
Deduct 2812 from 2980 and we're left 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.

In conclusion, the division gives 21991.344 with a balance of 0.0168.
