We look at the division of 48486831 by 803 
The aim is to understand the frequency of 803 in 48486831.

Let's proceed to step 1:
The number 803 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 803

Let's proceed to step 2:
803 goes into 48 0 times with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 803

Going ahead to step 3:
803 goes into 484 0 times with a remainder of 484.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 484 after subtracting 0 from 484.
Include the next digit (8) from the dividend after 484, then repeat: 4848 / 803

Moving on to step 4:
803 goes into 4848 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 30 after subtracting 4818 from 4848.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 803

Going ahead to step 5:
The number 803 fits into 306 0 times, leaving a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 306, we end up with 306.
Grab the next digit (8) from the dividend, add it to 306, then carry on: 3068 / 803

Moving on to step 6:
If we divide 3068 by 803, we get 3 and a remainder of 659.
Put 3 as the next digit of the answer. 
Result so far: 603.0
Subtract 2409 from 3068 to get 659.
Bring next digit (3) of the dividend behind the 659 and repeat the process: 6593 / 803

Moving on to step 7:
If we divide 6593 by 803, we get 8 and a remainder of 169.
Put 8 as the next digit of the answer. 
Result so far: 6038.0
Deduct 6424 from 6593 and we're left with 169.
Grab the next digit (1) from the dividend, add it to 169, then carry on: 1691 / 803

Going ahead to step 8:
803 goes into 1691 2 times with a remainder of 85.
Record the quotient 2 as the next digit in the result. 
Result so far: 60382.0
Subtract 1606 from 1691 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
The number 803 fits into 850 1 times, leaving a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 60382.1
Subtract 803 from 850 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
803 goes into 470 0 times with a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 60382.1
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
The number 803 fits into 4700 5 times, leaving a remainder of 685.
Put 5 as the next digit of the answer. 
Result so far: 60382.105
The remainder is 685 after subtracting 4015 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 12:
When dividing 6850 by 803, we get 8 with a remainder of 426.
Write down 8 as next digit of the result. 
Result so far: 60382.1058
Subtracting 6424 from 6850 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 13:
The number 803 fits into 4260 5 times, leaving a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 60382.10585
If we take 4015 away from 4260, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 14:
803 goes into 2450 3 times with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 60382.105853
Subtract 2409 from 2450 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
The number 803 fits into 410 0 times, leaving a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 60382.105853
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 16:
If we divide 4100 by 803, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 60382.10585305
Deduct 4015 from 4100 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 60382.10585305, with a leftover of 8.5e-08.
