We look at the division of 79663649 by 586 
The aim is to understand the frequency of 586 in 79663649.

Step 1:
586 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 586

Moving on to step 2:
When dividing 79 by 586, we get 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 586

Step 3:
The number 586 fits into 796 1 times, leaving a remainder of 210.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 586 from 796 to get 210.
Include the next digit (6) from the dividend after 210, then repeat: 2106 / 586

Moving on to step 4:
When dividing 2106 by 586, we get 3 with a remainder of 348.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 348 after subtracting 1758 from 2106.
Fetch the next digit (3) from the dividend, attach it to 348 and continue: 3483 / 586

Step 5:
If we divide 3483 by 586, we get 5 and a remainder of 553.
Put 5 as the next digit of the answer. 
Result so far: 135.0
If we take 2930 away from 3483, we end up with 553.
Append the next digit (6) from the dividend to 553 and continue with: 5536 / 586

Step 6:
If we divide 5536 by 586, we get 9 and a remainder of 262.
Record the quotient 9 as the next digit in the result. 
Result so far: 1359.0
If we take 5274 away from 5536, we end up with 262.
Grab the next digit (4) from the dividend, add it to 262, then carry on: 2624 / 586

Going ahead to step 7:
586 goes into 2624 4 times with a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 13594.0
If we subtract 2344 from 2624, we get 280.
Fetch the next digit (9) from the dividend, attach it to 280 and continue: 2809 / 586

Going ahead to step 8:
The number 586 fits into 2809 4 times, leaving a remainder of 465.
Use 4 as the next digit of our solution. 
Result so far: 135944.0
Deduct 2344 from 2809 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Moving on to step 9:
586 goes into 4650 7 times with a remainder of 548.
The next digit of our result is 7. 
Result so far: 135944.7
Deduct 4102 from 4650 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 10:
5480 divided by 586 is 9 with a remainder of 206.
Use 9 as the next digit of our solution. 
Result so far: 135944.79
If we subtract 5274 from 5480, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 11:
586 goes into 2060 3 times with a remainder of 302.
Use 3 as the next digit of our solution. 
Result so far: 135944.793
Subtracting 1758 from 2060 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 12:
586 can be fit into 3020 5 times, resulting in a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 135944.7935
The remainder is 90 after subtracting 2930 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
900 divided by 586 is 1 with a remainder of 314.
Record the quotient 1 as the next digit in the result. 
Result so far: 135944.79351
The remainder is 314 after subtracting 586 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 14:
586 goes into 3140 5 times with a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 135944.793515
Deduct 2930 from 3140 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 15:
If we divide 2100 by 586, we get 3 and a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 135944.7935153
If we take 1758 away from 2100, we end up 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.

Going ahead to step 16:
3420 divided by 586 is 5 with a remainder of 490.
Record the quotient 5 as the next digit in the result. 
Result so far: 135944.79351535
Subtracting 2930 from 3420 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

After the division, we end up with 135944.79351535 and a remainder of 4.9e-07.
