We look at the division of 81948239 by 492 
We're looking to find how many times 492 goes into 81948239.

On to step 1:
If we divide 8 by 492, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 492

Let's proceed to step 2:
81 divided by 492 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 492

Moving on to step 3:
If we divide 819 by 492, we get 1 and a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 492 away from 819, we end up with 327.
Fetch the next digit (4) from the dividend, attach it to 327 and continue: 3274 / 492

On to step 4:
If we divide 3274 by 492, we get 6 and a remainder of 322.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 2952 away from 3274, we end up with 322.
Grab the next digit (8) from the dividend, add it to 322, then carry on: 3228 / 492

Going ahead to step 5:
The number 492 fits into 3228 6 times, leaving a remainder of 276.
The next digit of our result is 6. 
Result so far: 166.0
If we take 2952 away from 3228, we end up with 276.
Grab the next digit (2) from the dividend, add it to 276, then carry on: 2762 / 492

On to step 6:
When dividing 2762 by 492, we get 5 with a remainder of 302.
Put 5 as the next digit of the answer. 
Result so far: 1665.0
Subtracting 2460 from 2762 leaves us with 302.
Bring next digit (3) of the dividend behind the 302 and repeat the process: 3023 / 492

On to step 7:
The number 492 fits into 3023 6 times, leaving a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 16656.0
Deduct 2952 from 3023 and we're left with 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 492

On to step 8:
If we divide 719 by 492, we get 1 and a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 166561.0
If we subtract 492 from 719, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 9:
If we divide 2270 by 492, we get 4 and a remainder of 302.
The next digit of our result is 4. 
Result so far: 166561.4
If we take 1968 away from 2270, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 10:
When dividing 3020 by 492, we get 6 with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 166561.46
If we subtract 2952 from 3020, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
If we divide 680 by 492, we get 1 and a remainder of 188.
Record the quotient 1 as the next digit in the result. 
Result so far: 166561.461
Subtracting 492 from 680 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 12:
1880 divided by 492 is 3 with a remainder of 404.
Put 3 as the next digit of the answer. 
Result so far: 166561.4613
The remainder is 404 after subtracting 1476 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 13:
The number 492 fits into 4040 8 times, leaving a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 166561.46138
If we subtract 3936 from 4040, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 14:
1040 divided by 492 is 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 166561.461382
If we subtract 984 from 1040, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 15:
492 can be fit into 560 1 times, resulting in a remainder of 68.
The next digit of our result is 1. 
Result so far: 166561.4613821
The remainder is 68 after subtracting 492 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 16:
The number 492 fits into 680 1 times, leaving a remainder of 188.
Put 1 as the next digit of the answer. 
Result so far: 166561.46138211
Subtract 492 from 680 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final outcome is 166561.46138211, with a leftover of 1.88e-07.
