We're dividing 51074513 by 666 
We want to figure out the number of times 51074513 can be divided by 666.

Let's proceed to step 1:
If we divide 5 by 666, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 666

Step 2:
If we divide 51 by 666, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 666

On to step 3:
510 divided by 666 is 0 with a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 510 to get 510.
Include the next digit (7) from the dividend after 510, then repeat: 5107 / 666

Going ahead to step 4:
The number 666 fits into 5107 7 times, leaving a remainder of 445.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 4662 from 5107 leaves us with 445.
Take the next digit (4) from the dividend and append it to 445, then repeat: 4454 / 666

On to step 5:
666 can be fit into 4454 6 times, resulting in a remainder of 458.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 3996 from 4454 and we're left with 458.
Fetch the next digit (5) from the dividend, attach it to 458 and continue: 4585 / 666

Moving on to step 6:
666 can be fit into 4585 6 times, resulting in a remainder of 589.
The next digit of our result is 6. 
Result so far: 766.0
Deduct 3996 from 4585 and we're left with 589.
Append the next digit (1) from the dividend to 589 and continue with: 5891 / 666

Going ahead to step 7:
When dividing 5891 by 666, we get 8 with a remainder of 563.
Write down 8 as next digit of the result. 
Result so far: 7668.0
Deduct 5328 from 5891 and we're left with 563.
Take the next digit (3) from the dividend and append it to 563, then repeat: 5633 / 666

Let's proceed to step 8:
666 can be fit into 5633 8 times, resulting in a remainder of 305.
Put 8 as the next digit of the answer. 
Result so far: 76688.0
Subtracting 5328 from 5633 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 9:
If we divide 3050 by 666, we get 4 and a remainder of 386.
Use 4 as the next digit of our solution. 
Result so far: 76688.4
The remainder is 386 after subtracting 2664 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 10:
666 goes into 3860 5 times with a remainder of 530.
Put 5 as the next digit of the answer. 
Result so far: 76688.45
Subtract 3330 from 3860 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.

Let's proceed to step 11:
666 can be fit into 5300 7 times, resulting in a remainder of 638.
Put 7 as the next digit of the answer. 
Result so far: 76688.457
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.

Let's proceed to step 12:
The number 666 fits into 6380 9 times, leaving a remainder of 386.
Write down 9 as next digit of the result. 
Result so far: 76688.4579
The remainder is 386 after subtracting 5994 from 6380.
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 13:
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: 76688.45795
If we subtract 3330 from 3860, we 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 14:
When dividing 5300 by 666, we get 7 with a remainder of 638.
Write down 7 as next digit of the result. 
Result so far: 76688.457957
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 15:
When dividing 6380 by 666, we get 9 with a remainder of 386.
Put 9 as the next digit of the answer. 
Result so far: 76688.4579579
If we take 5994 away from 6380, we end up 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.

On to step 16:
3860 divided by 666 is 5 with a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 76688.45795795
Subtract 3330 from 3860 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.

In conclusion, the division gives 76688.45795795 with a balance of 5.3e-07.
