15445989 ÷ 492 
We want to figure out the number of times 15445989 can be divided by 492.

Let's proceed to step 1:
492 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 492

Advancing to step 2:
If we divide 15 by 492, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 492

Advancing to step 3:
The number 492 fits into 154 0 times, leaving a remainder of 154.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Append the next digit (4) from the dividend to 154 and continue with: 1544 / 492

Advancing to step 4:
The number 492 fits into 1544 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1476 from 1544, we get 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 492

Going ahead to step 5:
If we divide 685 by 492, we get 1 and a remainder of 193.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 492 from 685 and we're left with 193.
Include the next digit (9) from the dividend after 193, then repeat: 1939 / 492

On to step 6:
492 goes into 1939 3 times with a remainder of 463.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
Deduct 1476 from 1939 and we're left with 463.
Take the next digit (8) from the dividend and append it to 463, then repeat: 4638 / 492

Step 7:
If we divide 4638 by 492, we get 9 and a remainder of 210.
The number 9 becomes the next digit in our result. 
Result so far: 3139.0
Subtracting 4428 from 4638 leaves us with 210.
Take the next digit (9) from the dividend and append it to 210, then repeat: 2109 / 492

Let's proceed to step 8:
If we divide 2109 by 492, we get 4 and a remainder of 141.
The number 4 becomes the next digit in our result. 
Result so far: 31394.0
If we subtract 1968 from 2109, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
492 can be fit into 1410 2 times, resulting in a remainder of 426.
The number 2 becomes the next digit in our result. 
Result so far: 31394.2
The remainder is 426 after subtracting 984 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 10:
The number 492 fits into 4260 8 times, leaving a remainder of 324.
Use 8 as the next digit of our solution. 
Result so far: 31394.28
If we subtract 3936 from 4260, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 11:
If we divide 3240 by 492, we get 6 and a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 31394.286
If we take 2952 away from 3240, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 12:
The number 492 fits into 2880 5 times, leaving a remainder of 420.
The next digit of our result is 5. 
Result so far: 31394.2865
The remainder is 420 after subtracting 2460 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 13:
492 goes into 4200 8 times with a remainder of 264.
The number 8 becomes the next digit in our result. 
Result so far: 31394.28658
Subtract 3936 from 4200 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 14:
When dividing 2640 by 492, we get 5 with a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 31394.286585
Subtract 2460 from 2640 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 15:
492 goes into 1800 3 times with a remainder of 324.
Put 3 as the next digit of the answer. 
Result so far: 31394.2865853
The remainder is 324 after subtracting 1476 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 16:
The number 492 fits into 3240 6 times, leaving a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 31394.28658536
Deduct 2952 from 3240 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 31394.28658536, and the remainder is 2.88e-07.
