30503389 divided by 486 
The aim is to understand the frequency of 486 in 30503389.

Going ahead to step 1:
When dividing 3 by 486, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 486

On to step 2:
When dividing 30 by 486, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 486

Going ahead to step 3:
486 goes into 305 0 times with a remainder of 305.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 305 to get 305.
Take the next digit (0) from the dividend and append it to 305, then repeat: 3050 / 486

Going ahead to step 4:
3050 divided by 486 is 6 with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 2916 from 3050 to get 134.
Append the next digit (3) from the dividend to 134 and continue with: 1343 / 486

Going ahead to step 5:
1343 divided by 486 is 2 with a remainder of 371.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtracting 972 from 1343 leaves us with 371.
Include the next digit (3) from the dividend after 371, then repeat: 3713 / 486

Step 6:
486 goes into 3713 7 times with a remainder of 311.
Use 7 as the next digit of our solution. 
Result so far: 627.0
Subtracting 3402 from 3713 leaves us with 311.
Grab the next digit (8) from the dividend, add it to 311, then carry on: 3118 / 486

Moving on to step 7:
If we divide 3118 by 486, we get 6 and a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 6276.0
If we subtract 2916 from 3118, we get 202.
Append the next digit (9) from the dividend to 202 and continue with: 2029 / 486

Going ahead to step 8:
486 can be fit into 2029 4 times, resulting in a remainder of 85.
Record the quotient 4 as the next digit in the result. 
Result so far: 62764.0
The remainder is 85 after subtracting 1944 from 2029.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 9:
When dividing 850 by 486, we get 1 with a remainder of 364.
Record the quotient 1 as the next digit in the result. 
Result so far: 62764.1
If we subtract 486 from 850, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 10:
486 goes into 3640 7 times with a remainder of 238.
Use 7 as the next digit of our solution. 
Result so far: 62764.17
If we take 3402 away from 3640, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 11:
2380 divided by 486 is 4 with a remainder of 436.
Record the quotient 4 as the next digit in the result. 
Result so far: 62764.174
If we subtract 1944 from 2380, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Going ahead to step 12:
486 goes into 4360 8 times with a remainder of 472.
Use 8 as the next digit of our solution. 
Result so far: 62764.1748
Deduct 3888 from 4360 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 13:
If we divide 4720 by 486, we get 9 and a remainder of 346.
The number 9 becomes the next digit in our result. 
Result so far: 62764.17489
If we subtract 4374 from 4720, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 14:
486 can be fit into 3460 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 62764.174897
The remainder is 58 after subtracting 3402 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 15:
580 divided by 486 is 1 with a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 62764.1748971
If we subtract 486 from 580, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 16:
486 goes into 940 1 times with a remainder of 454.
Use 1 as the next digit of our solution. 
Result so far: 62764.17489711
Subtract 486 from 940 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

The final result is 62764.17489711 with a remainder of 4.54e-07.
