Let's divide 51666993 by 5
We're looking to find how many times 5 goes into 51666993.

Going ahead to step 1:
5 goes into 5 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 5 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 5

Going ahead to step 2:
When dividing 1 by 5, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 5

Step 3:
5 can be fit into 16 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 103.0
If we take 15 away from 16, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 5

Let's proceed to step 4:
16 divided by 5 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1033.0
If we subtract 15 from 16, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 5

Moving on to step 5:
5 can be fit into 16 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 10333.0
The remainder is 1 after subtracting 15 from 16.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 5

On to step 6:
19 divided by 5 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 103333.0
The remainder is 4 after subtracting 15 from 19.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 5

On to step 7:
49 divided by 5 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 1033339.0
Subtracting 45 from 49 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 5

Moving on to step 8:
5 can be fit into 43 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 10333398.0
Subtract 40 from 43 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 10333398.6
Subtract 30 from 30 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10333398.6
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10333398.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10333398.6 with a balance of 0.0.
