We're dividing 337471 by 72 
The aim is to understand the frequency of 72 in 337471.

Step 1:
3 divided by 72 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 72

Step 2:
72 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 72

Step 3:
When dividing 337 by 72, we get 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 288 away from 337, we end up with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 72

Advancing to step 4:
72 goes into 494 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 62 after subtracting 432 from 494.
Take the next digit (7) from the dividend and append it to 62, then repeat: 627 / 72

Step 5:
If we divide 627 by 72, we get 8 and a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 468.0
If we take 576 away from 627, we end up with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 72

Going ahead to step 6:
The number 72 fits into 511 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 4687.0
Subtracting 504 from 511 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 72 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 4687.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
When dividing 700 by 72, we get 9 with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 4687.09
If we take 648 away from 700, we end up 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.

Step 9:
When dividing 520 by 72, we get 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 4687.097
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.

On to step 10:
If we divide 160 by 72, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4687.0972
Deduct 144 from 160 and we're left 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.

On to step 11:
72 goes into 160 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 4687.09722
Deduct 144 from 160 and we're left 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.

After the division, we end up with 4687.09722 and a remainder of 1.6e-05.
