8085166 ÷ 291 
We want to figure out the number of times 8085166 can be divided by 291.

Step 1:
When dividing 8 by 291, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 291

Advancing to step 2:
When dividing 80 by 291, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 291

On to step 3:
The number 291 fits into 808 2 times, leaving a remainder of 226.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 582 from 808 and we're left with 226.
Include the next digit (5) from the dividend after 226, then repeat: 2265 / 291

Going ahead to step 4:
2265 divided by 291 is 7 with a remainder of 228.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 2037 from 2265, we get 228.
Bring next digit (1) of the dividend behind the 228 and repeat the process: 2281 / 291

Advancing to step 5:
The number 291 fits into 2281 7 times, leaving a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 277.0
If we take 2037 away from 2281, we end up with 244.
Include the next digit (6) from the dividend after 244, then repeat: 2446 / 291

Going ahead to step 6:
2446 divided by 291 is 8 with a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 2778.0
Deduct 2328 from 2446 and we're left with 118.
Bring next digit (6) of the dividend behind the 118 and repeat the process: 1186 / 291

On to step 7:
If we divide 1186 by 291, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 27784.0
Subtract 1164 from 1186 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
When dividing 220 by 291, we get 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 27784.0
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 9:
If we divide 2200 by 291, we get 7 and a remainder of 163.
The next digit of our result is 7. 
Result so far: 27784.07
Deduct 2037 from 2200 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 10:
1630 divided by 291 is 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 27784.075
Deduct 1455 from 1630 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 11:
When dividing 1750 by 291, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 27784.0756
If we subtract 1746 from 1750, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
The number 291 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 27784.0756
If we subtract 0 from 40, 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.

Moving on to step 13:
400 divided by 291 is 1 with a remainder of 109.
The next digit of our result is 1. 
Result so far: 27784.075601
Subtract 291 from 400 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 14:
If we divide 1090 by 291, we get 3 and a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 27784.0756013
Deduct 873 from 1090 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 15:
If we divide 2170 by 291, we get 7 and a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 27784.07560137
If we subtract 2037 from 2170, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

In conclusion, the division gives 27784.07560137 with a balance of 1.33e-07.
