We look at the division of 15431968 by 99 
Let's see how many times 99 fits into 15431968.

Going ahead to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 99

Let's proceed to step 2:
99 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 99

Step 3:
When dividing 154 by 99, we get 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 99 from 154 to get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 99

Let's proceed to step 4:
99 goes into 553 5 times with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 495 away from 553, we end up with 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 99

Moving on to step 5:
If we divide 581 by 99, we get 5 and a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtracting 495 from 581 leaves us with 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 99

Moving on to step 6:
When dividing 869 by 99, we get 8 with a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 1558.0
If we take 792 away from 869, we end up with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 99

On to step 7:
If we divide 776 by 99, we get 7 and a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 15587.0
Subtracting 693 from 776 leaves us with 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 99

Step 8:
99 can be fit into 838 8 times, resulting in a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 155878.0
The remainder is 46 after subtracting 792 from 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
99 goes into 460 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 155878.4
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
640 divided by 99 is 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 155878.46
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
460 divided by 99 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 155878.464
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
99 goes into 640 6 times with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 155878.4646
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
460 divided by 99 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 155878.46464
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
640 divided by 99 is 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 155878.464646
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 15:
99 goes into 460 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 155878.4646464
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
640 divided by 99 is 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 155878.46464646
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 155878.46464646, with a leftover of 4.6e-08.
