Let's divide 77353129 by 415
The aim is to understand the frequency of 415 in 77353129.

Let's proceed to step 1:
If we divide 7 by 415, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 415

Moving on to step 2:
415 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 415

Step 3:
When dividing 773 by 415, we get 1 with a remainder of 358.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 415 from 773 to get 358.
Append the next digit (5) from the dividend to 358 and continue with: 3585 / 415

Step 4:
The number 415 fits into 3585 8 times, leaving a remainder of 265.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 3320 from 3585, we get 265.
Append the next digit (3) from the dividend to 265 and continue with: 2653 / 415

On to step 5:
415 goes into 2653 6 times with a remainder of 163.
Put 6 as the next digit of the answer. 
Result so far: 186.0
Subtracting 2490 from 2653 leaves us with 163.
Take the next digit (1) from the dividend and append it to 163, then repeat: 1631 / 415

Moving on to step 6:
When dividing 1631 by 415, we get 3 with a remainder of 386.
Put 3 as the next digit of the answer. 
Result so far: 1863.0
Deduct 1245 from 1631 and we're left with 386.
Fetch the next digit (2) from the dividend, attach it to 386 and continue: 3862 / 415

Advancing to step 7:
3862 divided by 415 is 9 with a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 18639.0
The remainder is 127 after subtracting 3735 from 3862.
Append the next digit (9) from the dividend to 127 and continue with: 1279 / 415

On to step 8:
If we divide 1279 by 415, we get 3 and a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 186393.0
The remainder is 34 after subtracting 1245 from 1279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
The number 415 fits into 340 0 times, leaving a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 186393.0
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
When dividing 3400 by 415, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 186393.08
Deduct 3320 from 3400 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
415 goes into 800 1 times with a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 186393.081
Subtract 415 from 800 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 12:
415 can be fit into 3850 9 times, resulting in a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 186393.0819
Subtract 3735 from 3850 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 13:
The number 415 fits into 1150 2 times, leaving a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 186393.08192
The remainder is 320 after subtracting 830 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
If we divide 3200 by 415, we get 7 and a remainder of 295.
Use 7 as the next digit of our solution. 
Result so far: 186393.081927
If we take 2905 away from 3200, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 15:
2950 divided by 415 is 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 186393.0819277
Subtract 2905 from 2950 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 186393.0819277 and a remainder of 4.5e-07.
