81494185 ÷ 492 
Our goal is to divide 81494185 by 492.

Let's proceed to step 1:
8 divided by 492 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 492

Advancing to step 2:
492 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 492

Let's proceed to step 3:
492 can be fit into 814 1 times, resulting in a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 492 from 814 leaves us with 322.
Grab the next digit (9) from the dividend, add it to 322, then carry on: 3229 / 492

On to step 4:
492 can be fit into 3229 6 times, resulting in a remainder of 277.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 2952 from 3229, we get 277.
Bring next digit (4) of the dividend behind the 277 and repeat the process: 2774 / 492

Going ahead to step 5:
492 goes into 2774 5 times with a remainder of 314.
The next digit of our result is 5. 
Result so far: 165.0
If we subtract 2460 from 2774, we get 314.
Bring next digit (1) of the dividend behind the 314 and repeat the process: 3141 / 492

Advancing to step 6:
492 can be fit into 3141 6 times, resulting in a remainder of 189.
Record the quotient 6 as the next digit in the result. 
Result so far: 1656.0
If we subtract 2952 from 3141, we get 189.
Grab the next digit (8) from the dividend, add it to 189, then carry on: 1898 / 492

Going ahead to step 7:
The number 492 fits into 1898 3 times, leaving a remainder of 422.
Write down 3 as next digit of the result. 
Result so far: 16563.0
Subtracting 1476 from 1898 leaves us with 422.
Include the next digit (5) from the dividend after 422, then repeat: 4225 / 492

Going ahead to step 8:
If we divide 4225 by 492, we get 8 and a remainder of 289.
The number 8 becomes the next digit in our result. 
Result so far: 165638.0
If we take 3936 away from 4225, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 9:
If we divide 2890 by 492, we get 5 and a remainder of 430.
Record the quotient 5 as the next digit in the result. 
Result so far: 165638.5
The remainder is 430 after subtracting 2460 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
If we divide 4300 by 492, we get 8 and a remainder of 364.
Put 8 as the next digit of the answer. 
Result so far: 165638.58
The remainder is 364 after subtracting 3936 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 11:
When dividing 3640 by 492, we get 7 with a remainder of 196.
The next digit of our result is 7. 
Result so far: 165638.587
Subtract 3444 from 3640 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 12:
When dividing 1960 by 492, we get 3 with a remainder of 484.
Write down 3 as next digit of the result. 
Result so far: 165638.5873
Subtract 1476 from 1960 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 13:
4840 divided by 492 is 9 with a remainder of 412.
Record the quotient 9 as the next digit in the result. 
Result so far: 165638.58739
Deduct 4428 from 4840 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 14:
492 goes into 4120 8 times with a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 165638.587398
Subtract 3936 from 4120 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 15:
492 goes into 1840 3 times with a remainder of 364.
Write down 3 as next digit of the result. 
Result so far: 165638.5873983
If we subtract 1476 from 1840, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 16:
The number 492 fits into 3640 7 times, leaving a remainder of 196.
Put 7 as the next digit of the answer. 
Result so far: 165638.58739837
If we subtract 3444 from 3640, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 165638.58739837, with a leftover of 1.96e-07.
