We look at the division of 7567647 by 583 
The aim is to understand the frequency of 583 in 7567647.

Moving on to step 1:
7 divided by 583 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 583

Moving on to step 2:
583 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 583

Going ahead to step 3:
583 can be fit into 756 1 times, resulting in a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 583 away from 756, we end up with 173.
Fetch the next digit (7) from the dividend, attach it to 173 and continue: 1737 / 583

Step 4:
583 can be fit into 1737 2 times, resulting in a remainder of 571.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 571 after subtracting 1166 from 1737.
Grab the next digit (6) from the dividend, add it to 571, then carry on: 5716 / 583

Going ahead to step 5:
583 goes into 5716 9 times with a remainder of 469.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Deduct 5247 from 5716 and we're left with 469.
Take the next digit (4) from the dividend and append it to 469, then repeat: 4694 / 583

Step 6:
The number 583 fits into 4694 8 times, leaving a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 1298.0
If we subtract 4664 from 4694, we get 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 583

Advancing to step 7:
When dividing 307 by 583, we get 0 with a remainder of 307.
Use 0 as the next digit of our solution. 
Result so far: 12980.0
Subtract 0 from 307 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 8:
The number 583 fits into 3070 5 times, leaving a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 12980.5
The remainder is 155 after subtracting 2915 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
583 can be fit into 1550 2 times, resulting in a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 12980.52
Deduct 1166 from 1550 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 10:
583 can be fit into 3840 6 times, resulting in a remainder of 342.
The next digit of our result is 6. 
Result so far: 12980.526
Deduct 3498 from 3840 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 11:
583 can be fit into 3420 5 times, resulting in a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 12980.5265
Subtract 2915 from 3420 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 12:
5050 divided by 583 is 8 with a remainder of 386.
The number 8 becomes the next digit in our result. 
Result so far: 12980.52658
Subtracting 4664 from 5050 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 13:
The number 583 fits into 3860 6 times, leaving a remainder of 362.
Put 6 as the next digit of the answer. 
Result so far: 12980.526586
Subtract 3498 from 3860 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 14:
If we divide 3620 by 583, we get 6 and a remainder of 122.
Write down 6 as next digit of the result. 
Result so far: 12980.5265866
The remainder is 122 after subtracting 3498 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

After the division, we end up with 12980.5265866 and a remainder of 1.22e-06.
