Let's divide 72912173 by 6
Let's see how many times 6 fits into 72912173.

Moving on to step 1:
The number 6 fits into 7 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 6 from 7 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 6

Let's proceed to step 2:
12 divided by 6 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 12 away from 12, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 6

On to step 3:
When dividing 9 by 6, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 121.0
The remainder is 3 after subtracting 6 from 9.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 6

Let's proceed to step 4:
When dividing 31 by 6, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1215.0
If we subtract 30 from 31, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 6

Let's proceed to step 5:
The number 6 fits into 12 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12152.0
If we subtract 12 from 12, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 6

On to step 6:
6 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 121520.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 6

On to step 7:
When dividing 17 by 6, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 1215202.0
Deduct 12 from 17 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 6

Step 8:
The number 6 fits into 53 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 12152028.0
If we subtract 48 from 53, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 6, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 12152028.8
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
If we divide 20 by 6, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 12152028.83
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 12152028.833
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 12152028.833, and the remainder is 0.0002.
