12513443 ÷ 492 
Let's see how many times 492 fits into 12513443.

Step 1:
492 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 492

Moving on to step 2:
492 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 492

On to step 3:
125 divided by 492 is 0 with a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 125 and we're left with 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 492

Advancing to step 4:
When dividing 1251 by 492, we get 2 with a remainder of 267.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 267 after subtracting 984 from 1251.
Append the next digit (3) from the dividend to 267 and continue with: 2673 / 492

Advancing to step 5:
When dividing 2673 by 492, we get 5 with a remainder of 213.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 2460 from 2673 and we're left with 213.
Take the next digit (4) from the dividend and append it to 213, then repeat: 2134 / 492

Moving on to step 6:
492 can be fit into 2134 4 times, resulting in a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 254.0
Subtract 1968 from 2134 to get 166.
Take the next digit (4) from the dividend and append it to 166, then repeat: 1664 / 492

On to step 7:
The number 492 fits into 1664 3 times, leaving a remainder of 188.
The next digit of our result is 3. 
Result so far: 2543.0
Subtracting 1476 from 1664 leaves us with 188.
Bring next digit (3) of the dividend behind the 188 and repeat the process: 1883 / 492

On to step 8:
1883 divided by 492 is 3 with a remainder of 407.
The number 3 becomes the next digit in our result. 
Result so far: 25433.0
If we take 1476 away from 1883, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 9:
492 goes into 4070 8 times with a remainder of 134.
Use 8 as the next digit of our solution. 
Result so far: 25433.8
If we take 3936 away from 4070, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
492 goes into 1340 2 times with a remainder of 356.
Put 2 as the next digit of the answer. 
Result so far: 25433.82
If we subtract 984 from 1340, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 11:
When dividing 3560 by 492, we get 7 with a remainder of 116.
Use 7 as the next digit of our solution. 
Result so far: 25433.827
If we subtract 3444 from 3560, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 12:
492 goes into 1160 2 times with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 25433.8272
If we subtract 984 from 1160, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 13:
1760 divided by 492 is 3 with a remainder of 284.
Use 3 as the next digit of our solution. 
Result so far: 25433.82723
If we take 1476 away from 1760, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 14:
492 goes into 2840 5 times with a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 25433.827235
If we take 2460 away from 2840, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
492 goes into 3800 7 times with a remainder of 356.
Record the quotient 7 as the next digit in the result. 
Result so far: 25433.8272357
If we subtract 3444 from 3800, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 16:
492 goes into 3560 7 times with a remainder of 116.
The number 7 becomes the next digit in our result. 
Result so far: 25433.82723577
If we subtract 3444 from 3560, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 25433.82723577, and the remainder is 1.16e-07.
