We divide 7232648 by 486
The aim is to understand the frequency of 486 in 7232648.

Going ahead to step 1:
7 divided by 486 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 486

On to step 2:
486 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 486

Advancing to step 3:
The number 486 fits into 723 1 times, leaving a remainder of 237.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 486 away from 723, we end up with 237.
Fetch the next digit (2) from the dividend, attach it to 237 and continue: 2372 / 486

Going ahead to step 4:
The number 486 fits into 2372 4 times, leaving a remainder of 428.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1944 from 2372 to get 428.
Include the next digit (6) from the dividend after 428, then repeat: 4286 / 486

Advancing to step 5:
The number 486 fits into 4286 8 times, leaving a remainder of 398.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtract 3888 from 4286 to get 398.
Append the next digit (4) from the dividend to 398 and continue with: 3984 / 486

Advancing to step 6:
The number 486 fits into 3984 8 times, leaving a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 1488.0
Deduct 3888 from 3984 and we're left with 96.
Grab the next digit (8) from the dividend, add it to 96, then carry on: 968 / 486

Moving on to step 7:
486 goes into 968 1 times with a remainder of 482.
Use 1 as the next digit of our solution. 
Result so far: 14881.0
Subtract 486 from 968 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 8:
The number 486 fits into 4820 9 times, leaving a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 14881.9
If we subtract 4374 from 4820, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 9:
When dividing 4460 by 486, we get 9 with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 14881.99
Subtracting 4374 from 4460 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.

The quotient of the division is 14881.99, and the remainder is 0.086.
