We divide 87839959 by 479
The aim is to understand the frequency of 479 in 87839959.

On to step 1:
If we divide 8 by 479, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 479

Step 2:
87 divided by 479 is 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 479

Let's proceed to step 3:
479 can be fit into 878 1 times, resulting in a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 479 from 878 leaves us with 399.
Grab the next digit (3) from the dividend, add it to 399, then carry on: 3993 / 479

Step 4:
3993 divided by 479 is 8 with a remainder of 161.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 161 after subtracting 3832 from 3993.
Include the next digit (9) from the dividend after 161, then repeat: 1619 / 479

Step 5:
If we divide 1619 by 479, we get 3 and a remainder of 182.
The next digit of our result is 3. 
Result so far: 183.0
If we subtract 1437 from 1619, we get 182.
Take the next digit (9) from the dividend and append it to 182, then repeat: 1829 / 479

Step 6:
If we divide 1829 by 479, we get 3 and a remainder of 392.
Use 3 as the next digit of our solution. 
Result so far: 1833.0
If we subtract 1437 from 1829, we get 392.
Include the next digit (5) from the dividend after 392, then repeat: 3925 / 479

On to step 7:
If we divide 3925 by 479, we get 8 and a remainder of 93.
The number 8 becomes the next digit in our result. 
Result so far: 18338.0
If we subtract 3832 from 3925, we get 93.
Append the next digit (9) from the dividend to 93 and continue with: 939 / 479

On to step 8:
479 can be fit into 939 1 times, resulting in a remainder of 460.
The next digit of our result is 1. 
Result so far: 183381.0
The remainder is 460 after subtracting 479 from 939.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 9:
If we divide 4600 by 479, we get 9 and a remainder of 289.
Record the quotient 9 as the next digit in the result. 
Result so far: 183381.9
The remainder is 289 after subtracting 4311 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 10:
When dividing 2890 by 479, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 183381.96
Deduct 2874 from 2890 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
479 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 183381.96
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
The number 479 fits into 1600 3 times, leaving a remainder of 163.
The next digit of our result is 3. 
Result so far: 183381.9603
The remainder is 163 after subtracting 1437 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 13:
If we divide 1630 by 479, we get 3 and a remainder of 193.
Record the quotient 3 as the next digit in the result. 
Result so far: 183381.96033
If we take 1437 away from 1630, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

The final outcome is 183381.96033, with a leftover of 0.000193.
