We look at the division of 80962883 by 615 
The aim is to understand the frequency of 615 in 80962883.

Let's proceed to step 1:
The number 615 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 615

Going ahead to step 2:
80 divided by 615 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 615

Moving on to step 3:
When dividing 809 by 615, we get 1 with a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 194 after subtracting 615 from 809.
Fetch the next digit (6) from the dividend, attach it to 194 and continue: 1946 / 615

Going ahead to step 4:
If we divide 1946 by 615, we get 3 and a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1845 from 1946 and we're left with 101.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 615

Step 5:
If we divide 1012 by 615, we get 1 and a remainder of 397.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we take 615 away from 1012, we end up with 397.
Append the next digit (8) from the dividend to 397 and continue with: 3978 / 615

Advancing to step 6:
The number 615 fits into 3978 6 times, leaving a remainder of 288.
Put 6 as the next digit of the answer. 
Result so far: 1316.0
Subtract 3690 from 3978 to get 288.
Grab the next digit (8) from the dividend, add it to 288, then carry on: 2888 / 615

Step 7:
The number 615 fits into 2888 4 times, leaving a remainder of 428.
Record the quotient 4 as the next digit in the result. 
Result so far: 13164.0
Deduct 2460 from 2888 and we're left with 428.
Append the next digit (3) from the dividend to 428 and continue with: 4283 / 615

Advancing to step 8:
615 goes into 4283 6 times with a remainder of 593.
The number 6 becomes the next digit in our result. 
Result so far: 131646.0
The remainder is 593 after subtracting 3690 from 4283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Let's proceed to step 9:
5930 divided by 615 is 9 with a remainder of 395.
The next digit of our result is 9. 
Result so far: 131646.9
Subtracting 5535 from 5930 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 10:
615 goes into 3950 6 times with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 131646.96
Deduct 3690 from 3950 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
The number 615 fits into 2600 4 times, leaving a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 131646.964
If we subtract 2460 from 2600, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
615 can be fit into 1400 2 times, resulting in a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 131646.9642
Subtracting 1230 from 1400 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 13:
If we divide 1700 by 615, we get 2 and a remainder of 470.
The number 2 becomes the next digit in our result. 
Result so far: 131646.96422
If we subtract 1230 from 1700, we 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.

Our division results in 131646.96422 with a remaining 0.00047.
