We look at the division of 516651 by 66 
We want to figure out the number of times 516651 can be divided by 66.

Moving on to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our 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 / 66

Let's proceed to step 2:
51 divided by 66 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 66

On to step 3:
If we divide 516 by 66, we get 7 and a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 462 from 516 and we're left with 54.
Grab the next digit (6) from the dividend, add it to 54, then carry on: 546 / 66

Let's proceed to step 4:
66 can be fit into 546 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 528 away from 546, we end up with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 66

Let's proceed to step 5:
If we divide 185 by 66, we get 2 and a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 782.0
Subtract 132 from 185 to get 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 66

Moving on to step 6:
66 goes into 531 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 7828.0
Deduct 528 from 531 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 66, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7828.0
If we take 0 away from 30, we end up 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.

Moving on to step 8:
When dividing 300 by 66, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 7828.04
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
66 goes into 360 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7828.045
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 66, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 7828.0454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
66 goes into 360 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7828.04545
If we take 330 away from 360, we end up 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.

Let's proceed to step 12:
300 divided by 66 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 7828.045454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 7828.0454545
Deduct 330 from 360 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.

Moving on to step 14:
300 divided by 66 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 7828.04545454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 7828.04545454, with a leftover of 3.6e-08.
