We're dividing 64521290 by 462 
The aim is to understand the frequency of 462 in 64521290.

Advancing to step 1:
462 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
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 462

On to step 2:
64 divided by 462 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 462

Step 3:
462 can be fit into 645 1 times, resulting in a remainder of 183.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 462 from 645 to get 183.
Include the next digit (2) from the dividend after 183, then repeat: 1832 / 462

Going ahead to step 4:
462 goes into 1832 3 times with a remainder of 446.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 446 after subtracting 1386 from 1832.
Fetch the next digit (1) from the dividend, attach it to 446 and continue: 4461 / 462

On to step 5:
If we divide 4461 by 462, we get 9 and a remainder of 303.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 4158 from 4461 to get 303.
Include the next digit (2) from the dividend after 303, then repeat: 3032 / 462

On to step 6:
When dividing 3032 by 462, we get 6 with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 1396.0
If we subtract 2772 from 3032, we get 260.
Append the next digit (9) from the dividend to 260 and continue with: 2609 / 462

Going ahead to step 7:
2609 divided by 462 is 5 with a remainder of 299.
Record the quotient 5 as the next digit in the result. 
Result so far: 13965.0
Subtract 2310 from 2609 to get 299.
Bring next digit (0) of the dividend behind the 299 and repeat the process: 2990 / 462

Step 8:
462 goes into 2990 6 times with a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 139656.0
Deduct 2772 from 2990 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
The number 462 fits into 2180 4 times, leaving a remainder of 332.
The number 4 becomes the next digit in our result. 
Result so far: 139656.4
Subtracting 1848 from 2180 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 10:
3320 divided by 462 is 7 with a remainder of 86.
The next digit of our result is 7. 
Result so far: 139656.47
Subtracting 3234 from 3320 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
462 goes into 860 1 times with a remainder of 398.
The number 1 becomes the next digit in our result. 
Result so far: 139656.471
Subtracting 462 from 860 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 12:
If we divide 3980 by 462, we get 8 and a remainder of 284.
Use 8 as the next digit of our solution. 
Result so far: 139656.4718
If we take 3696 away from 3980, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 13:
462 can be fit into 2840 6 times, resulting in a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 139656.47186
If we take 2772 away from 2840, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
462 goes into 680 1 times with a remainder of 218.
Write down 1 as next digit of the result. 
Result so far: 139656.471861
Deduct 462 from 680 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 15:
The number 462 fits into 2180 4 times, leaving a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 139656.4718614
Deduct 1848 from 2180 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 16:
The number 462 fits into 3320 7 times, leaving a remainder of 86.
Use 7 as the next digit of our solution. 
Result so far: 139656.47186147
The remainder is 86 after subtracting 3234 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 139656.47186147 and a remainder of 8.6e-08.
