We're dividing 77371509 by 479 
The aim is to understand the frequency of 479 in 77371509.

Advancing to step 1:
If we divide 7 by 479, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 479

Step 2:
479 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 479

Step 3:
479 can be fit into 773 1 times, resulting in a remainder of 294.
The next digit of our result is 1. 
Result so far: 1.0
If we take 479 away from 773, we end up with 294.
Bring next digit (7) of the dividend behind the 294 and repeat the process: 2947 / 479

Let's proceed to step 4:
479 goes into 2947 6 times with a remainder of 73.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 73 after subtracting 2874 from 2947.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 479

Let's proceed to step 5:
If we divide 731 by 479, we get 1 and a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Deduct 479 from 731 and we're left with 252.
Include the next digit (5) from the dividend after 252, then repeat: 2525 / 479

Step 6:
If we divide 2525 by 479, we get 5 and a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 1615.0
Subtracting 2395 from 2525 leaves us with 130.
Include the next digit (0) from the dividend after 130, then repeat: 1300 / 479

Going ahead to step 7:
If we divide 1300 by 479, we get 2 and a remainder of 342.
Write down 2 as next digit of the result. 
Result so far: 16152.0
If we take 958 away from 1300, we end up with 342.
Take the next digit (9) from the dividend and append it to 342, then repeat: 3429 / 479

On to step 8:
When dividing 3429 by 479, we get 7 with a remainder of 76.
The next digit of our result is 7. 
Result so far: 161527.0
If we subtract 3353 from 3429, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
479 goes into 760 1 times with a remainder of 281.
Use 1 as the next digit of our solution. 
Result so far: 161527.1
If we subtract 479 from 760, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 10:
479 goes into 2810 5 times with a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 161527.15
Deduct 2395 from 2810 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 11:
When dividing 4150 by 479, we get 8 with a remainder of 318.
The number 8 becomes the next digit in our result. 
Result so far: 161527.158
The remainder is 318 after subtracting 3832 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 12:
The number 479 fits into 3180 6 times, leaving a remainder of 306.
The next digit of our result is 6. 
Result so far: 161527.1586
If we take 2874 away from 3180, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 13:
3060 divided by 479 is 6 with a remainder of 186.
The next digit of our result is 6. 
Result so far: 161527.15866
If we subtract 2874 from 3060, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final result is 161527.15866 with a remainder of 0.000186.
