Our goal is to divide 81907096 by 166.

Going ahead to step 1:
8 divided by 166 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 166

Moving on to step 2:
81 divided by 166 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 166

On to step 3:
If we divide 819 by 166, we get 4 and a remainder of 155.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 664 from 819 and we're left with 155.
Include the next digit (0) from the dividend after 155, then repeat: 1550 / 166

Going ahead to step 4:
1550 divided by 166 is 9 with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 1494 from 1550, we get 56.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 166

Step 5:
When dividing 567 by 166, we get 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 493.0
If we subtract 498 from 567, we get 69.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 166

On to step 6:
166 goes into 690 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 4934.0
Subtract 664 from 690 to get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 166

On to step 7:
When dividing 269 by 166, we get 1 with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 49341.0
The remainder is 103 after subtracting 166 from 269.
Append the next digit (6) from the dividend to 103 and continue with: 1036 / 166

Moving on to step 8:
The number 166 fits into 1036 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 493416.0
If we subtract 996 from 1036, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
166 can be fit into 400 2 times, resulting in a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 493416.2
Subtract 332 from 400 to 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.

Moving on to step 10:
When dividing 680 by 166, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 493416.24
If we subtract 664 from 680, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 166 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 493416.24
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
When dividing 1600 by 166, we get 9 with a remainder of 106.
Put 9 as the next digit of the answer. 
Result so far: 493416.2409
The remainder is 106 after subtracting 1494 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 13:
When dividing 1060 by 166, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 493416.24096
If we subtract 996 from 1060, we 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.

Going ahead to step 14:
The number 166 fits into 640 3 times, leaving a remainder of 142.
The next digit of our result is 3. 
Result so far: 493416.240963
If we take 498 away from 640, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 15:
If we divide 1420 by 166, we get 8 and a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 493416.2409638
The remainder is 92 after subtracting 1328 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 16:
166 can be fit into 920 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 493416.24096385
Deduct 830 from 920 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 493416.24096385 with a remainder of 9e-08.
