We divide 77177025 by 915
The aim is to understand the frequency of 915 in 77177025.

Step 1:
When dividing 7 by 915, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 915

Let's proceed to step 2:
915 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 915

Advancing to step 3:
915 can be fit into 771 0 times, resulting in a remainder of 771.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 771, we get 771.
Bring next digit (7) of the dividend behind the 771 and repeat the process: 7717 / 915

Step 4:
7717 divided by 915 is 8 with a remainder of 397.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7320 away from 7717, we end up with 397.
Append the next digit (7) from the dividend to 397 and continue with: 3977 / 915

Step 5:
915 goes into 3977 4 times with a remainder of 317.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 317 after subtracting 3660 from 3977.
Bring next digit (0) of the dividend behind the 317 and repeat the process: 3170 / 915

Advancing to step 6:
When dividing 3170 by 915, we get 3 with a remainder of 425.
The number 3 becomes the next digit in our result. 
Result so far: 843.0
Subtracting 2745 from 3170 leaves us with 425.
Bring next digit (2) of the dividend behind the 425 and repeat the process: 4252 / 915

Let's proceed to step 7:
4252 divided by 915 is 4 with a remainder of 592.
The number 4 becomes the next digit in our result. 
Result so far: 8434.0
The remainder is 592 after subtracting 3660 from 4252.
Fetch the next digit (5) from the dividend, attach it to 592 and continue: 5925 / 915

Let's proceed to step 8:
If we divide 5925 by 915, we get 6 and a remainder of 435.
The next digit of our result is 6. 
Result so far: 84346.0
The remainder is 435 after subtracting 5490 from 5925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 9:
4350 divided by 915 is 4 with a remainder of 690.
Record the quotient 4 as the next digit in the result. 
Result so far: 84346.4
The remainder is 690 after subtracting 3660 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 10:
When dividing 6900 by 915, we get 7 with a remainder of 495.
Write down 7 as next digit of the result. 
Result so far: 84346.47
Subtracting 6405 from 6900 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 11:
If we divide 4950 by 915, we get 5 and a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 84346.475
The remainder is 375 after subtracting 4575 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 12:
915 can be fit into 3750 4 times, resulting in a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 84346.4754
If we take 3660 away from 3750, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
915 goes into 900 0 times with a remainder of 900.
Record the quotient 0 as the next digit in the result. 
Result so far: 84346.4754
The remainder is 900 after subtracting 0 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Step 14:
The number 915 fits into 9000 9 times, leaving a remainder of 765.
Put 9 as the next digit of the answer. 
Result so far: 84346.475409
The remainder is 765 after subtracting 8235 from 9000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 15:
When dividing 7650 by 915, we get 8 with a remainder of 330.
The number 8 becomes the next digit in our result. 
Result so far: 84346.4754098
If we take 7320 away from 7650, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 16:
915 can be fit into 3300 3 times, resulting in a remainder of 555.
Use 3 as the next digit of our solution. 
Result so far: 84346.47540983
If we take 2745 away from 3300, we end up 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 final outcome is 84346.47540983, with a leftover of 5.55e-07.
