Let's divide 12840481 by 615
The aim is to understand the frequency of 615 in 12840481.

Moving on to step 1:
If we divide 1 by 615, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 615

Moving on to step 2:
The number 615 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 615

Step 3:
615 goes into 128 0 times with a remainder of 128.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Bring next digit (4) of the dividend behind the 128 and repeat the process: 1284 / 615

Advancing to step 4:
The number 615 fits into 1284 2 times, leaving a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1230 from 1284 and we're left with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 615

Step 5:
The number 615 fits into 540 0 times, leaving a remainder of 540.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 540 and we're left with 540.
Fetch the next digit (4) from the dividend, attach it to 540 and continue: 5404 / 615

Moving on to step 6:
The number 615 fits into 5404 8 times, leaving a remainder of 484.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
If we subtract 4920 from 5404, we get 484.
Include the next digit (8) from the dividend after 484, then repeat: 4848 / 615

Going ahead to step 7:
The number 615 fits into 4848 7 times, leaving a remainder of 543.
The number 7 becomes the next digit in our result. 
Result so far: 2087.0
Subtracting 4305 from 4848 leaves us with 543.
Append the next digit (1) from the dividend to 543 and continue with: 5431 / 615

Let's proceed to step 8:
The number 615 fits into 5431 8 times, leaving a remainder of 511.
Record the quotient 8 as the next digit in the result. 
Result so far: 20878.0
Subtract 4920 from 5431 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 9:
615 can be fit into 5110 8 times, resulting in a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 20878.8
The remainder is 190 after subtracting 4920 from 5110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
615 goes into 1900 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 20878.83
The remainder is 55 after subtracting 1845 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
If we divide 550 by 615, we get 0 and a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 20878.83
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 12:
The number 615 fits into 5500 8 times, leaving a remainder of 580.
Write down 8 as next digit of the result. 
Result so far: 20878.8308
If we take 4920 away from 5500, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 13:
If we divide 5800 by 615, we get 9 and a remainder of 265.
Put 9 as the next digit of the answer. 
Result so far: 20878.83089
If we subtract 5535 from 5800, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 14:
When dividing 2650 by 615, we get 4 with a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 20878.830894
Subtracting 2460 from 2650 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 15:
When dividing 1900 by 615, we get 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 20878.8308943
Deduct 1845 from 1900 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 16:
The number 615 fits into 550 0 times, leaving a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 20878.8308943
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

The quotient of the division is 20878.8308943, and the remainder is 5.5e-07.
