We look at the division of 583187 by 49 
The aim is to understand the frequency of 49 in 583187.

Let's proceed to step 1:
If we divide 5 by 49, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 49

Step 2:
The number 49 fits into 58 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 9 after subtracting 49 from 58.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 49

Let's proceed to step 3:
The number 49 fits into 93 1 times, leaving a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 49 from 93 to get 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 49

Going ahead to step 4:
When dividing 441 by 49, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtract 441 from 441 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 49

Step 5:
8 divided by 49 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 1190.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 49

Going ahead to step 6:
When dividing 87 by 49, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 11901.0
Subtract 49 from 87 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
380 divided by 49 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 11901.7
If we take 343 away from 380, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
If we divide 370 by 49, we get 7 and a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 11901.77
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 11901.77 with a remaining 0.027.
