We're dividing 64676591 by 524 
The aim is to understand the frequency of 524 in 64676591.

Advancing to step 1:
524 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 524

Going ahead to step 2:
The number 524 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 524

Advancing to step 3:
524 goes into 646 1 times with a remainder of 122.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 524 from 646 leaves us with 122.
Fetch the next digit (7) from the dividend, attach it to 122 and continue: 1227 / 524

Going ahead to step 4:
When dividing 1227 by 524, we get 2 with a remainder of 179.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1048 from 1227 and we're left with 179.
Bring next digit (6) of the dividend behind the 179 and repeat the process: 1796 / 524

On to step 5:
524 can be fit into 1796 3 times, resulting in a remainder of 224.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtracting 1572 from 1796 leaves us with 224.
Grab the next digit (5) from the dividend, add it to 224, then carry on: 2245 / 524

On to step 6:
The number 524 fits into 2245 4 times, leaving a remainder of 149.
Write down 4 as next digit of the result. 
Result so far: 1234.0
Subtracting 2096 from 2245 leaves us with 149.
Take the next digit (9) from the dividend and append it to 149, then repeat: 1499 / 524

Moving on to step 7:
524 can be fit into 1499 2 times, resulting in a remainder of 451.
Record the quotient 2 as the next digit in the result. 
Result so far: 12342.0
Deduct 1048 from 1499 and we're left with 451.
Take the next digit (1) from the dividend and append it to 451, then repeat: 4511 / 524

Going ahead to step 8:
The number 524 fits into 4511 8 times, leaving a remainder of 319.
Record the quotient 8 as the next digit in the result. 
Result so far: 123428.0
If we subtract 4192 from 4511, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 9:
The number 524 fits into 3190 6 times, leaving a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 123428.6
The remainder is 46 after subtracting 3144 from 3190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
524 goes into 460 0 times with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 123428.6
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 11:
When dividing 4600 by 524, we get 8 with a remainder of 408.
Put 8 as the next digit of the answer. 
Result so far: 123428.608
Subtracting 4192 from 4600 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 12:
When dividing 4080 by 524, we get 7 with a remainder of 412.
Put 7 as the next digit of the answer. 
Result so far: 123428.6087
Deduct 3668 from 4080 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 13:
The number 524 fits into 4120 7 times, leaving a remainder of 452.
Record the quotient 7 as the next digit in the result. 
Result so far: 123428.60877
The remainder is 452 after subtracting 3668 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The quotient of the division is 123428.60877, and the remainder is 0.000452.
