6869642 ÷ 866 
Our goal is to divide 6869642 by 866.

Advancing to step 1:
866 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 866

Advancing to step 2:
The number 866 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 866

Moving on to step 3:
866 goes into 686 0 times with a remainder of 686.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 686 leaves us with 686.
Grab the next digit (9) from the dividend, add it to 686, then carry on: 6869 / 866

On to step 4:
The number 866 fits into 6869 7 times, leaving a remainder of 807.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6062 from 6869 leaves us with 807.
Grab the next digit (6) from the dividend, add it to 807, then carry on: 8076 / 866

Moving on to step 5:
The number 866 fits into 8076 9 times, leaving a remainder of 282.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtract 7794 from 8076 to get 282.
Bring next digit (4) of the dividend behind the 282 and repeat the process: 2824 / 866

Step 6:
When dividing 2824 by 866, we get 3 with a remainder of 226.
The next digit of our result is 3. 
Result so far: 793.0
Deduct 2598 from 2824 and we're left with 226.
Grab the next digit (2) from the dividend, add it to 226, then carry on: 2262 / 866

Moving on to step 7:
If we divide 2262 by 866, we get 2 and a remainder of 530.
Record the quotient 2 as the next digit in the result. 
Result so far: 7932.0
Subtract 1732 from 2262 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 8:
If we divide 5300 by 866, we get 6 and a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 7932.6
Deduct 5196 from 5300 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 9:
866 goes into 1040 1 times with a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 7932.61
Deduct 866 from 1040 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
866 can be fit into 1740 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7932.612
Subtracting 1732 from 1740 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 866 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 7932.612
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
866 can be fit into 800 0 times, resulting in a remainder of 800.
The next digit of our result is 0. 
Result so far: 7932.612
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 7932.612, with a leftover of 0.0008.
