We divide 80963742 by 515
The aim is to understand the frequency of 515 in 80963742.

On to step 1:
The number 515 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 515

On to step 2:
80 divided by 515 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 515

Going ahead to step 3:
If we divide 809 by 515, we get 1 and a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 515 from 809, we get 294.
Append the next digit (6) from the dividend to 294 and continue with: 2946 / 515

Advancing to step 4:
The number 515 fits into 2946 5 times, leaving a remainder of 371.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2575 from 2946 to get 371.
Grab the next digit (3) from the dividend, add it to 371, then carry on: 3713 / 515

Going ahead to step 5:
The number 515 fits into 3713 7 times, leaving a remainder of 108.
The next digit of our result is 7. 
Result so far: 157.0
Subtracting 3605 from 3713 leaves us with 108.
Include the next digit (7) from the dividend after 108, then repeat: 1087 / 515

Advancing to step 6:
515 can be fit into 1087 2 times, resulting in a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 1572.0
Subtracting 1030 from 1087 leaves us with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 515

Advancing to step 7:
515 can be fit into 574 1 times, resulting in a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 15721.0
If we take 515 away from 574, we end up with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 515

Advancing to step 8:
The number 515 fits into 592 1 times, leaving a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 157211.0
If we take 515 away from 592, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
515 goes into 770 1 times with a remainder of 255.
Put 1 as the next digit of the answer. 
Result so far: 157211.1
If we subtract 515 from 770, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 10:
If we divide 2550 by 515, we get 4 and a remainder of 490.
The number 4 becomes the next digit in our result. 
Result so far: 157211.14
Subtract 2060 from 2550 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 11:
4900 divided by 515 is 9 with a remainder of 265.
Put 9 as the next digit of the answer. 
Result so far: 157211.149
If we take 4635 away from 4900, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 12:
515 can be fit into 2650 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 157211.1495
The remainder is 75 after subtracting 2575 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
When dividing 750 by 515, we get 1 with a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 157211.14951
Deduct 515 from 750 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 14:
515 goes into 2350 4 times with a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 157211.149514
Subtract 2060 from 2350 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 15:
If we divide 2900 by 515, we get 5 and a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 157211.1495145
Subtract 2575 from 2900 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 16:
If we divide 3250 by 515, we get 6 and a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 157211.14951456
If we subtract 3090 from 3250, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 157211.14951456, with a leftover of 1.6e-07.
