We look at the division of 28931964 by 615 
The aim is to understand the frequency of 615 in 28931964.

Moving on to step 1:
If we divide 2 by 615, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 615

Advancing to step 2:
615 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 615

Step 3:
615 can be fit into 289 0 times, resulting in a remainder of 289.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 289, we end up with 289.
Fetch the next digit (3) from the dividend, attach it to 289 and continue: 2893 / 615

Let's proceed to step 4:
615 goes into 2893 4 times with a remainder of 433.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 2460 from 2893, we get 433.
Fetch the next digit (1) from the dividend, attach it to 433 and continue: 4331 / 615

Let's proceed to step 5:
When dividing 4331 by 615, we get 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 4305 from 4331 to get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 615

Going ahead to step 6:
615 goes into 269 0 times with a remainder of 269.
Use 0 as the next digit of our solution. 
Result so far: 470.0
Subtract 0 from 269 to get 269.
Take the next digit (6) from the dividend and append it to 269, then repeat: 2696 / 615

On to step 7:
When dividing 2696 by 615, we get 4 with a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 4704.0
Subtract 2460 from 2696 to get 236.
Bring next digit (4) of the dividend behind the 236 and repeat the process: 2364 / 615

Moving on to step 8:
615 goes into 2364 3 times with a remainder of 519.
The number 3 becomes the next digit in our result. 
Result so far: 47043.0
The remainder is 519 after subtracting 1845 from 2364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Step 9:
The number 615 fits into 5190 8 times, leaving a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 47043.8
Deduct 4920 from 5190 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
615 can be fit into 2700 4 times, resulting in a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 47043.84
Subtract 2460 from 2700 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
2400 divided by 615 is 3 with a remainder of 555.
Use 3 as the next digit of our solution. 
Result so far: 47043.843
The remainder is 555 after subtracting 1845 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 12:
When dividing 5550 by 615, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 47043.8439
If we take 5535 away from 5550, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
When dividing 150 by 615, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 47043.8439
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
The number 615 fits into 1500 2 times, leaving a remainder of 270.
The number 2 becomes the next digit in our result. 
Result so far: 47043.843902
If we take 1230 away from 1500, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 15:
615 goes into 2700 4 times with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 47043.8439024
If we subtract 2460 from 2700, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
615 can be fit into 2400 3 times, resulting in a remainder of 555.
The number 3 becomes the next digit in our result. 
Result so far: 47043.84390243
Deduct 1845 from 2400 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The quotient of the division is 47043.84390243, and the remainder is 5.55e-07.
