Let's divide 86839793 by 666
We want to divide 86839793 by 666.

Step 1:
666 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 666

Step 2:
86 divided by 666 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 666

Let's proceed to step 3:
If we divide 868 by 666, we get 1 and a remainder of 202.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 666 from 868 to get 202.
Bring next digit (3) of the dividend behind the 202 and repeat the process: 2023 / 666

Let's proceed to step 4:
The number 666 fits into 2023 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 25 after subtracting 1998 from 2023.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 666

Going ahead to step 5:
666 goes into 259 0 times with a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Deduct 0 from 259 and we're left with 259.
Grab the next digit (7) from the dividend, add it to 259, then carry on: 2597 / 666

Advancing to step 6:
The number 666 fits into 2597 3 times, leaving a remainder of 599.
Write down 3 as next digit of the result. 
Result so far: 1303.0
Subtracting 1998 from 2597 leaves us with 599.
Bring next digit (9) of the dividend behind the 599 and repeat the process: 5999 / 666

Moving on to step 7:
When dividing 5999 by 666, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 13039.0
Subtract 5994 from 5999 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 666

Moving on to step 8:
666 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 130390.0
Subtract 0 from 53 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
666 can be fit into 530 0 times, resulting in a remainder of 530.
The next digit of our result is 0. 
Result so far: 130390.0
Subtract 0 from 530 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.

On to step 10:
If we divide 5300 by 666, we get 7 and a remainder of 638.
Record the quotient 7 as the next digit in the result. 
Result so far: 130390.07
Subtract 4662 from 5300 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 11:
666 goes into 6380 9 times with a remainder of 386.
Use 9 as the next digit of our solution. 
Result so far: 130390.079
Deduct 5994 from 6380 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 12:
666 goes into 3860 5 times with a remainder of 530.
The next digit of our result is 5. 
Result so far: 130390.0795
Deduct 3330 from 3860 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 13:
When dividing 5300 by 666, we get 7 with a remainder of 638.
Use 7 as the next digit of our solution. 
Result so far: 130390.07957
If we subtract 4662 from 5300, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 14:
If we divide 6380 by 666, we get 9 and a remainder of 386.
Put 9 as the next digit of the answer. 
Result so far: 130390.079579
Subtracting 5994 from 6380 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 15:
666 can be fit into 3860 5 times, resulting in a remainder of 530.
Record the quotient 5 as the next digit in the result. 
Result so far: 130390.0795795
Subtracting 3330 from 3860 leaves us with 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 16:
666 goes into 5300 7 times with a remainder of 638.
Record the quotient 7 as the next digit in the result. 
Result so far: 130390.07957957
If we take 4662 away from 5300, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

The final outcome is 130390.07957957, with a leftover of 6.38e-07.
