43702892 ÷ 615 
The aim is to understand the frequency of 615 in 43702892.

Step 1:
4 divided by 615 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 615

Going ahead to step 2:
If we divide 43 by 615, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 615

On to step 3:
If we divide 437 by 615, we get 0 and a remainder of 437.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 437, we get 437.
Include the next digit (0) from the dividend after 437, then repeat: 4370 / 615

Let's proceed to step 4:
The number 615 fits into 4370 7 times, leaving a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4305 from 4370, we get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 615

On to step 5:
615 can be fit into 652 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 615 away from 652, we end up with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 615

Moving on to step 6:
The number 615 fits into 378 0 times, leaving a remainder of 378.
Put 0 as the next digit of the answer. 
Result so far: 710.0
Subtracting 0 from 378 leaves us with 378.
Fetch the next digit (9) from the dividend, attach it to 378 and continue: 3789 / 615

Let's proceed to step 7:
If we divide 3789 by 615, we get 6 and a remainder of 99.
Put 6 as the next digit of the answer. 
Result so far: 7106.0
If we take 3690 away from 3789, we end up with 99.
Take the next digit (2) from the dividend and append it to 99, then repeat: 992 / 615

Moving on to step 8:
615 goes into 992 1 times with a remainder of 377.
Write down 1 as next digit of the result. 
Result so far: 71061.0
If we take 615 away from 992, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 9:
615 can be fit into 3770 6 times, resulting in a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 71061.6
If we subtract 3690 from 3770, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
If we divide 800 by 615, we get 1 and a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 71061.61
Deduct 615 from 800 and we're left 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 11:
If we divide 1850 by 615, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 71061.613
If we subtract 1845 from 1850, 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.

Going ahead to step 12:
When dividing 50 by 615, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 71061.613
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
The number 615 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 71061.613
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 71061.613 with a remainder of 0.0005.
