Let's divide 72216540 by 515
The aim is to understand the frequency of 515 in 72216540.

Step 1:
If we divide 7 by 515, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 515

Going ahead to step 2:
When dividing 72 by 515, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 515

Let's proceed to step 3:
The number 515 fits into 722 1 times, leaving a remainder of 207.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 515 from 722 to get 207.
Grab the next digit (1) from the dividend, add it to 207, then carry on: 2071 / 515

Let's proceed to step 4:
When dividing 2071 by 515, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2060 from 2071 and we're left with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 515

Step 5:
116 divided by 515 is 0 with a remainder of 116.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtracting 0 from 116 leaves us with 116.
Fetch the next digit (5) from the dividend, attach it to 116 and continue: 1165 / 515

Let's proceed to step 6:
515 goes into 1165 2 times with a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 1402.0
If we subtract 1030 from 1165, we get 135.
Include the next digit (4) from the dividend after 135, then repeat: 1354 / 515

On to step 7:
The number 515 fits into 1354 2 times, leaving a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 14022.0
The remainder is 324 after subtracting 1030 from 1354.
Bring next digit (0) of the dividend behind the 324 and repeat the process: 3240 / 515

Let's proceed to step 8:
The number 515 fits into 3240 6 times, leaving a remainder of 150.
Use 6 as the next digit of our solution. 
Result so far: 140226.0
The remainder is 150 after subtracting 3090 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
1500 divided by 515 is 2 with a remainder of 470.
Use 2 as the next digit of our solution. 
Result so far: 140226.2
Subtract 1030 from 1500 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 10:
The number 515 fits into 4700 9 times, leaving a remainder of 65.
The next digit of our result is 9. 
Result so far: 140226.29
Deduct 4635 from 4700 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 11:
515 goes into 650 1 times with a remainder of 135.
The next digit of our result is 1. 
Result so far: 140226.291
The remainder is 135 after subtracting 515 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 12:
When dividing 1350 by 515, we get 2 with a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 140226.2912
Subtracting 1030 from 1350 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
515 can be fit into 3200 6 times, resulting in a remainder of 110.
Use 6 as the next digit of our solution. 
Result so far: 140226.29126
Subtract 3090 from 3200 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 14:
When dividing 1100 by 515, we get 2 with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 140226.291262
The remainder is 70 after subtracting 1030 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
515 goes into 700 1 times with a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 140226.2912621
If we take 515 away from 700, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 16:
1850 divided by 515 is 3 with a remainder of 305.
Put 3 as the next digit of the answer. 
Result so far: 140226.29126213
If we take 1545 away from 1850, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Our division results in 140226.29126213 with a remaining 3.05e-07.
