310966 divided by 72 
The aim is to understand the frequency of 72 in 310966.

Step 1:
72 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 72

Let's proceed to step 2:
The number 72 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 72

Going ahead to step 3:
72 goes into 310 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 288 from 310 and we're left with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 72

Going ahead to step 4:
If we divide 229 by 72, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 216 away from 229, we end up with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 72

Going ahead to step 5:
72 can be fit into 136 1 times, resulting in a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 431.0
If we take 72 away from 136, we end up with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 72

On to step 6:
The number 72 fits into 646 8 times, leaving a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 4318.0
The remainder is 70 after subtracting 576 from 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
72 goes into 700 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 4318.9
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
72 goes into 520 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 4318.97
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
72 goes into 160 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4318.972
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 4318.9722
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 4318.9722, with a leftover of 0.00016.
