64181953 ÷ 488 
The aim is to understand the frequency of 488 in 64181953.

Going ahead to step 1:
When dividing 6 by 488, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 488

Advancing to step 2:
If we divide 64 by 488, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 488

Going ahead to step 3:
If we divide 641 by 488, we get 1 and a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 488 from 641 to get 153.
Take the next digit (8) from the dividend and append it to 153, then repeat: 1538 / 488

On to step 4:
When dividing 1538 by 488, we get 3 with a remainder of 74.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1464 from 1538 and we're left with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 488

Moving on to step 5:
If we divide 741 by 488, we get 1 and a remainder of 253.
Use 1 as the next digit of our solution. 
Result so far: 131.0
The remainder is 253 after subtracting 488 from 741.
Grab the next digit (9) from the dividend, add it to 253, then carry on: 2539 / 488

On to step 6:
488 goes into 2539 5 times with a remainder of 99.
Write down 5 as next digit of the result. 
Result so far: 1315.0
If we subtract 2440 from 2539, we get 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 488

Advancing to step 7:
995 divided by 488 is 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 13152.0
Subtract 976 from 995 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 488

Step 8:
The number 488 fits into 193 0 times, leaving a remainder of 193.
The next digit of our result is 0. 
Result so far: 131520.0
Deduct 0 from 193 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
If we divide 1930 by 488, we get 3 and a remainder of 466.
The number 3 becomes the next digit in our result. 
Result so far: 131520.3
Deduct 1464 from 1930 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 10:
The number 488 fits into 4660 9 times, leaving a remainder of 268.
Put 9 as the next digit of the answer. 
Result so far: 131520.39
Subtract 4392 from 4660 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 11:
If we divide 2680 by 488, we get 5 and a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 131520.395
Subtracting 2440 from 2680 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
2400 divided by 488 is 4 with a remainder of 448.
Record the quotient 4 as the next digit in the result. 
Result so far: 131520.3954
Subtract 1952 from 2400 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 13:
488 goes into 4480 9 times with a remainder of 88.
The next digit of our result is 9. 
Result so far: 131520.39549
The remainder is 88 after subtracting 4392 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 14:
When dividing 880 by 488, we get 1 with a remainder of 392.
The number 1 becomes the next digit in our result. 
Result so far: 131520.395491
Deduct 488 from 880 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 15:
When dividing 3920 by 488, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 131520.3954918
Subtracting 3904 from 3920 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
488 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 131520.3954918
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 131520.3954918 with a balance of 1.6e-07.
