Let's divide 51164919 by 666
Our goal is to divide 51164919 by 666.

On to step 1:
The number 666 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 666

Let's proceed to step 2:
51 divided by 666 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 666

On to step 3:
666 goes into 511 0 times with a remainder of 511.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 511 after subtracting 0 from 511.
Bring next digit (6) of the dividend behind the 511 and repeat the process: 5116 / 666

Advancing to step 4:
When dividing 5116 by 666, we get 7 with a remainder of 454.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 4662 from 5116 and we're left with 454.
Bring next digit (4) of the dividend behind the 454 and repeat the process: 4544 / 666

Let's proceed to step 5:
If we divide 4544 by 666, we get 6 and a remainder of 548.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 3996 from 4544 and we're left with 548.
Grab the next digit (9) from the dividend, add it to 548, then carry on: 5489 / 666

On to step 6:
666 goes into 5489 8 times with a remainder of 161.
Write down 8 as next digit of the result. 
Result so far: 768.0
Subtracting 5328 from 5489 leaves us with 161.
Include the next digit (1) from the dividend after 161, then repeat: 1611 / 666

On to step 7:
666 can be fit into 1611 2 times, resulting in a remainder of 279.
The number 2 becomes the next digit in our result. 
Result so far: 7682.0
Subtracting 1332 from 1611 leaves us with 279.
Append the next digit (9) from the dividend to 279 and continue with: 2799 / 666

Let's proceed to step 8:
666 can be fit into 2799 4 times, resulting in a remainder of 135.
Put 4 as the next digit of the answer. 
Result so far: 76824.0
Deduct 2664 from 2799 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 9:
The number 666 fits into 1350 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 76824.2
Subtract 1332 from 1350 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
When dividing 180 by 666, we get 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 76824.2
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
The number 666 fits into 1800 2 times, leaving a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 76824.202
If we take 1332 away from 1800, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 12:
666 can be fit into 4680 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 76824.2027
Subtracting 4662 from 4680 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
666 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 76824.2027
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 14:
666 can be fit into 1800 2 times, resulting in a remainder of 468.
Write down 2 as next digit of the result. 
Result so far: 76824.202702
Deduct 1332 from 1800 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 15:
666 goes into 4680 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 76824.2027027
If we take 4662 away from 4680, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
180 divided by 666 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 76824.2027027
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 76824.2027027, and the remainder is 1.8e-07.
