21039005 divided by 482 
The aim is to understand the frequency of 482 in 21039005.

On to step 1:
482 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 482

Going ahead to step 2:
The number 482 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 482

Let's proceed to step 3:
The number 482 fits into 210 0 times, leaving a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Take the next digit (3) from the dividend and append it to 210, then repeat: 2103 / 482

On to step 4:
482 goes into 2103 4 times with a remainder of 175.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1928 from 2103 and we're left with 175.
Append the next digit (9) from the dividend to 175 and continue with: 1759 / 482

On to step 5:
If we divide 1759 by 482, we get 3 and a remainder of 313.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 1446 from 1759 to get 313.
Grab the next digit (0) from the dividend, add it to 313, then carry on: 3130 / 482

Advancing to step 6:
482 goes into 3130 6 times with a remainder of 238.
Write down 6 as next digit of the result. 
Result so far: 436.0
Subtracting 2892 from 3130 leaves us with 238.
Include the next digit (0) from the dividend after 238, then repeat: 2380 / 482

On to step 7:
482 goes into 2380 4 times with a remainder of 452.
Record the quotient 4 as the next digit in the result. 
Result so far: 4364.0
If we take 1928 away from 2380, we end up with 452.
Fetch the next digit (5) from the dividend, attach it to 452 and continue: 4525 / 482

Advancing to step 8:
The number 482 fits into 4525 9 times, leaving a remainder of 187.
Record the quotient 9 as the next digit in the result. 
Result so far: 43649.0
Deduct 4338 from 4525 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
If we divide 1870 by 482, we get 3 and a remainder of 424.
Put 3 as the next digit of the answer. 
Result so far: 43649.3
Deduct 1446 from 1870 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 10:
When dividing 4240 by 482, we get 8 with a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 43649.38
If we take 3856 away from 4240, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 11:
482 goes into 3840 7 times with a remainder of 466.
Put 7 as the next digit of the answer. 
Result so far: 43649.387
If we subtract 3374 from 3840, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 12:
4660 divided by 482 is 9 with a remainder of 322.
Record the quotient 9 as the next digit in the result. 
Result so far: 43649.3879
The remainder is 322 after subtracting 4338 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 13:
482 goes into 3220 6 times with a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 43649.38796
Subtracting 2892 from 3220 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 14:
When dividing 3280 by 482, we get 6 with a remainder of 388.
Use 6 as the next digit of our solution. 
Result so far: 43649.387966
Subtract 2892 from 3280 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 43649.387966 and a remainder of 3.88e-05.
