79874178 ÷ 583 
The aim is to understand the frequency of 583 in 79874178.

On to step 1:
7 divided by 583 is 0 with 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.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 583

Let's proceed to step 2:
If we divide 79 by 583, we get 0 and a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 583

Let's proceed to step 3:
The number 583 fits into 798 1 times, leaving a remainder of 215.
The next digit of our result is 1. 
Result so far: 1.0
If we take 583 away from 798, we end up with 215.
Fetch the next digit (7) from the dividend, attach it to 215 and continue: 2157 / 583

On to step 4:
583 can be fit into 2157 3 times, resulting in a remainder of 408.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 408 after subtracting 1749 from 2157.
Bring next digit (4) of the dividend behind the 408 and repeat the process: 4084 / 583

Moving on to step 5:
If we divide 4084 by 583, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
The remainder is 3 after subtracting 4081 from 4084.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 583

Moving on to step 6:
583 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 1370.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 583

Going ahead to step 7:
When dividing 317 by 583, we get 0 with a remainder of 317.
The next digit of our result is 0. 
Result so far: 13700.0
If we subtract 0 from 317, we get 317.
Take the next digit (8) from the dividend and append it to 317, then repeat: 3178 / 583

Going ahead to step 8:
If we divide 3178 by 583, we get 5 and a remainder of 263.
Put 5 as the next digit of the answer. 
Result so far: 137005.0
The remainder is 263 after subtracting 2915 from 3178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 9:
The number 583 fits into 2630 4 times, leaving a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 137005.4
If we subtract 2332 from 2630, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 10:
583 can be fit into 2980 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 137005.45
The remainder is 65 after subtracting 2915 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
The number 583 fits into 650 1 times, leaving a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 137005.451
If we subtract 583 from 650, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 12:
The number 583 fits into 670 1 times, leaving a remainder of 87.
The next digit of our result is 1. 
Result so far: 137005.4511
If we subtract 583 from 670, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final result is 137005.4511 with a remainder of 0.00087.
