68094210 ÷ 866 
We want to figure out the number of times 68094210 can be divided by 866.

Going ahead to step 1:
When dividing 6 by 866, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 866

Moving on to step 2:
68 divided by 866 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 866

Let's proceed to step 3:
866 goes into 680 0 times with a remainder of 680.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 680 and we're left with 680.
Grab the next digit (9) from the dividend, add it to 680, then carry on: 6809 / 866

Step 4:
If we divide 6809 by 866, we get 7 and a remainder of 747.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6062 from 6809 and we're left with 747.
Take the next digit (4) from the dividend and append it to 747, then repeat: 7474 / 866

Going ahead to step 5:
866 can be fit into 7474 8 times, resulting in a remainder of 546.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 546 after subtracting 6928 from 7474.
Grab the next digit (2) from the dividend, add it to 546, then carry on: 5462 / 866

Let's proceed to step 6:
5462 divided by 866 is 6 with a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 786.0
Subtract 5196 from 5462 to get 266.
Append the next digit (1) from the dividend to 266 and continue with: 2661 / 866

Moving on to step 7:
When dividing 2661 by 866, we get 3 with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 7863.0
Deduct 2598 from 2661 and we're left with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 866

Step 8:
866 goes into 630 0 times with a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 78630.0
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 9:
When dividing 6300 by 866, we get 7 with a remainder of 238.
Record the quotient 7 as the next digit in the result. 
Result so far: 78630.7
The remainder is 238 after subtracting 6062 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 10:
The number 866 fits into 2380 2 times, leaving a remainder of 648.
The number 2 becomes the next digit in our result. 
Result so far: 78630.72
Subtract 1732 from 2380 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 11:
The number 866 fits into 6480 7 times, leaving a remainder of 418.
Use 7 as the next digit of our solution. 
Result so far: 78630.727
If we subtract 6062 from 6480, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 12:
If we divide 4180 by 866, we get 4 and a remainder of 716.
Put 4 as the next digit of the answer. 
Result so far: 78630.7274
If we take 3464 away from 4180, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 13:
866 goes into 7160 8 times with a remainder of 232.
The next digit of our result is 8. 
Result so far: 78630.72748
If we take 6928 away from 7160, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 14:
The number 866 fits into 2320 2 times, leaving a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 78630.727482
Subtract 1732 from 2320 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 15:
866 can be fit into 5880 6 times, resulting in a remainder of 684.
Use 6 as the next digit of our solution. 
Result so far: 78630.7274826
Subtract 5196 from 5880 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 16:
866 can be fit into 6840 7 times, resulting in a remainder of 778.
The number 7 becomes the next digit in our result. 
Result so far: 78630.72748267
If we take 6062 away from 6840, we end up with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

After the division, we end up with 78630.72748267 and a remainder of 7.78e-07.
