86790792 ÷ 666 
We want to figure out the number of times 86790792 can be divided by 666.

Going ahead to step 1:
8 divided by 666 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 666

Let's proceed to step 2:
86 divided by 666 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 666

Let's proceed to step 3:
When dividing 867 by 666, we get 1 with a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 666 from 867 leaves us with 201.
Grab the next digit (9) from the dividend, add it to 201, then carry on: 2019 / 666

Let's proceed to step 4:
2019 divided by 666 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1998 away from 2019, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 666

Step 5:
666 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 130.0
The remainder is 210 after subtracting 0 from 210.
Bring next digit (7) of the dividend behind the 210 and repeat the process: 2107 / 666

Let's proceed to step 6:
The number 666 fits into 2107 3 times, leaving a remainder of 109.
Write down 3 as next digit of the result. 
Result so far: 1303.0
If we take 1998 away from 2107, we end up with 109.
Include the next digit (9) from the dividend after 109, then repeat: 1099 / 666

Let's proceed to step 7:
The number 666 fits into 1099 1 times, leaving a remainder of 433.
Use 1 as the next digit of our solution. 
Result so far: 13031.0
If we subtract 666 from 1099, we get 433.
Grab the next digit (2) from the dividend, add it to 433, then carry on: 4332 / 666

Let's proceed to step 8:
The number 666 fits into 4332 6 times, leaving a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 130316.0
Deduct 3996 from 4332 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 9:
When dividing 3360 by 666, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 130316.5
If we subtract 3330 from 3360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
When dividing 300 by 666, we get 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 130316.5
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
3000 divided by 666 is 4 with a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 130316.504
The remainder is 336 after subtracting 2664 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 12:
If we divide 3360 by 666, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 130316.5045
If we subtract 3330 from 3360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
666 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 130316.5045
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
3000 divided by 666 is 4 with a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 130316.504504
Deduct 2664 from 3000 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 15:
If we divide 3360 by 666, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 130316.5045045
Deduct 3330 from 3360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 16:
If we divide 300 by 666, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 130316.5045045
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 130316.5045045 with a balance of 3e-07.
