We look at the division of 2515332 by 583 
The aim is to understand the frequency of 583 in 2515332.

On to step 1:
583 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 583

On to step 2:
583 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 583

Step 3:
583 can be fit into 251 0 times, resulting in a remainder of 251.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 251 to get 251.
Bring next digit (5) of the dividend behind the 251 and repeat the process: 2515 / 583

Advancing to step 4:
If we divide 2515 by 583, we get 4 and a remainder of 183.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2332 from 2515, we get 183.
Bring next digit (3) of the dividend behind the 183 and repeat the process: 1833 / 583

Moving on to step 5:
1833 divided by 583 is 3 with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 1749 away from 1833, we end up with 84.
Append the next digit (3) from the dividend to 84 and continue with: 843 / 583

Going ahead to step 6:
If we divide 843 by 583, we get 1 and a remainder of 260.
Use 1 as the next digit of our solution. 
Result so far: 431.0
Subtracting 583 from 843 leaves us with 260.
Fetch the next digit (2) from the dividend, attach it to 260 and continue: 2602 / 583

Going ahead to step 7:
The number 583 fits into 2602 4 times, leaving a remainder of 270.
The next digit of our result is 4. 
Result so far: 4314.0
If we take 2332 away from 2602, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 8:
2700 divided by 583 is 4 with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 4314.4
Subtract 2332 from 2700 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 9:
The number 583 fits into 3680 6 times, leaving a remainder of 182.
Put 6 as the next digit of the answer. 
Result so far: 4314.46
Deduct 3498 from 3680 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 10:
The number 583 fits into 1820 3 times, leaving a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 4314.463
If we subtract 1749 from 1820, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 11:
710 divided by 583 is 1 with a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 4314.4631
Deduct 583 from 710 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 12:
If we divide 1270 by 583, we get 2 and a remainder of 104.
The next digit of our result is 2. 
Result so far: 4314.46312
Subtract 1166 from 1270 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 13:
When dividing 1040 by 583, we get 1 with a remainder of 457.
Write down 1 as next digit of the result. 
Result so far: 4314.463121
If we subtract 583 from 1040, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 14:
4570 divided by 583 is 7 with a remainder of 489.
Write down 7 as next digit of the result. 
Result so far: 4314.4631217
Subtracting 4081 from 4570 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Going ahead to step 15:
If we divide 4890 by 583, we get 8 and a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 4314.46312178
Deduct 4664 from 4890 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

After the division, we end up with 4314.46312178 and a remainder of 2.26e-07.
