Let's divide 54312462 by 666
We want to divide 54312462 by 666.

Going ahead to step 1:
5 divided by 666 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 666

On to step 2:
666 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 666

On to step 3:
666 can be fit into 543 0 times, resulting in a remainder of 543.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 543, we get 543.
Grab the next digit (1) from the dividend, add it to 543, then carry on: 5431 / 666

Moving on to step 4:
5431 divided by 666 is 8 with a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5328 from 5431 and we're left with 103.
Append the next digit (2) from the dividend to 103 and continue with: 1032 / 666

Step 5:
The number 666 fits into 1032 1 times, leaving a remainder of 366.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 666 from 1032 leaves us with 366.
Fetch the next digit (4) from the dividend, attach it to 366 and continue: 3664 / 666

Step 6:
If we divide 3664 by 666, we get 5 and a remainder of 334.
Write down 5 as next digit of the result. 
Result so far: 815.0
If we subtract 3330 from 3664, we get 334.
Include the next digit (6) from the dividend after 334, then repeat: 3346 / 666

Advancing to step 7:
When dividing 3346 by 666, we get 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 8155.0
Subtracting 3330 from 3346 leaves us with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 666

Advancing to step 8:
If we divide 162 by 666, we get 0 and a remainder of 162.
The next digit of our result is 0. 
Result so far: 81550.0
If we take 0 away from 162, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 9:
1620 divided by 666 is 2 with a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 81550.2
Subtract 1332 from 1620 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 10:
The number 666 fits into 2880 4 times, leaving a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 81550.24
Subtract 2664 from 2880 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 11:
If we divide 2160 by 666, we get 3 and a remainder of 162.
Record the quotient 3 as the next digit in the result. 
Result so far: 81550.243
Deduct 1998 from 2160 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 12:
The number 666 fits into 1620 2 times, leaving a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 81550.2432
If we take 1332 away from 1620, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 13:
When dividing 2880 by 666, we get 4 with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 81550.24324
If we take 2664 away from 2880, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 14:
666 goes into 2160 3 times with a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 81550.243243
Subtracting 1998 from 2160 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 15:
666 goes into 1620 2 times with a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 81550.2432432
If we subtract 1332 from 1620, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 16:
666 can be fit into 2880 4 times, resulting in a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 81550.24324324
If we take 2664 away from 2880, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Our division results in 81550.24324324 with a remaining 2.16e-07.
