We look at the division of 80819313 by 866 
We want to figure out the number of times 80819313 can be divided by 866.

Let's proceed to step 1:
If we divide 8 by 866, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 866

Going ahead to step 2:
866 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 866

Let's proceed to step 3:
When dividing 808 by 866, we get 0 with a remainder of 808.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 808 and we're left with 808.
Bring next digit (1) of the dividend behind the 808 and repeat the process: 8081 / 866

On to step 4:
866 goes into 8081 9 times with a remainder of 287.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7794 from 8081 and we're left with 287.
Take the next digit (9) from the dividend and append it to 287, then repeat: 2879 / 866

Going ahead to step 5:
866 can be fit into 2879 3 times, resulting in a remainder of 281.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtract 2598 from 2879 to get 281.
Fetch the next digit (3) from the dividend, attach it to 281 and continue: 2813 / 866

Advancing to step 6:
If we divide 2813 by 866, we get 3 and a remainder of 215.
Put 3 as the next digit of the answer. 
Result so far: 933.0
If we take 2598 away from 2813, we end up with 215.
Bring next digit (1) of the dividend behind the 215 and repeat the process: 2151 / 866

Going ahead to step 7:
The number 866 fits into 2151 2 times, leaving a remainder of 419.
The number 2 becomes the next digit in our result. 
Result so far: 9332.0
If we subtract 1732 from 2151, we get 419.
Fetch the next digit (3) from the dividend, attach it to 419 and continue: 4193 / 866

Advancing to step 8:
4193 divided by 866 is 4 with a remainder of 729.
The number 4 becomes the next digit in our result. 
Result so far: 93324.0
If we subtract 3464 from 4193, we get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Let's proceed to step 9:
866 goes into 7290 8 times with a remainder of 362.
Put 8 as the next digit of the answer. 
Result so far: 93324.8
Deduct 6928 from 7290 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 10:
3620 divided by 866 is 4 with a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 93324.84
If we take 3464 away from 3620, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
When dividing 1560 by 866, we get 1 with a remainder of 694.
Write down 1 as next digit of the result. 
Result so far: 93324.841
If we take 866 away from 1560, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Let's proceed to step 12:
6940 divided by 866 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 93324.8418
The remainder is 12 after subtracting 6928 from 6940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
When dividing 120 by 866, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 93324.8418
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
866 goes into 1200 1 times with a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 93324.841801
If we subtract 866 from 1200, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 15:
If we divide 3340 by 866, we get 3 and a remainder of 742.
Put 3 as the next digit of the answer. 
Result so far: 93324.8418013
Subtract 2598 from 3340 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Moving on to step 16:
7420 divided by 866 is 8 with a remainder of 492.
Use 8 as the next digit of our solution. 
Result so far: 93324.84180138
The remainder is 492 after subtracting 6928 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

After the division, we end up with 93324.84180138 and a remainder of 4.92e-07.
