We look at the division of 81166302 by 373 
Let's see how many times 373 fits into 81166302.

Step 1:
If we divide 8 by 373, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 373

Step 2:
373 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 373

Moving on to step 3:
When dividing 811 by 373, we get 2 with a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 746 from 811 leaves us with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 373

On to step 4:
373 goes into 656 1 times with a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 373 away from 656, we end up with 283.
Fetch the next digit (6) from the dividend, attach it to 283 and continue: 2836 / 373

Step 5:
373 goes into 2836 7 times with a remainder of 225.
Use 7 as the next digit of our solution. 
Result so far: 217.0
If we subtract 2611 from 2836, we get 225.
Take the next digit (3) from the dividend and append it to 225, then repeat: 2253 / 373

Going ahead to step 6:
When dividing 2253 by 373, we get 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 2176.0
The remainder is 15 after subtracting 2238 from 2253.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 373

Let's proceed to step 7:
373 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 21760.0
If we take 0 away from 150, we end up with 150.
Include the next digit (2) from the dividend after 150, then repeat: 1502 / 373

On to step 8:
The number 373 fits into 1502 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 217604.0
The remainder is 10 after subtracting 1492 from 1502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 373, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 217604.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
When dividing 1000 by 373, we get 2 with a remainder of 254.
The next digit of our result is 2. 
Result so far: 217604.02
Deduct 746 from 1000 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 11:
373 goes into 2540 6 times with a remainder of 302.
Use 6 as the next digit of our solution. 
Result so far: 217604.026
The remainder is 302 after subtracting 2238 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 12:
373 can be fit into 3020 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 217604.0268
The remainder is 36 after subtracting 2984 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
If we divide 360 by 373, we get 0 and a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 217604.0268
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 14:
373 goes into 3600 9 times with a remainder of 243.
Record the quotient 9 as the next digit in the result. 
Result so far: 217604.026809
Subtracting 3357 from 3600 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 15:
The number 373 fits into 2430 6 times, leaving a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 217604.0268096
If we subtract 2238 from 2430, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 16:
The number 373 fits into 1920 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 217604.02680965
The remainder is 55 after subtracting 1865 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 217604.02680965 with a remainder of 5.5e-08.
