78278313 divided by 486 
The aim is to understand the frequency of 486 in 78278313.

On to step 1:
7 divided by 486 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 486

Let's proceed to step 2:
The number 486 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 486

Advancing to step 3:
486 goes into 782 1 times with a remainder of 296.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 486 from 782 leaves us with 296.
Take the next digit (7) from the dividend and append it to 296, then repeat: 2967 / 486

Going ahead to step 4:
2967 divided by 486 is 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 2916 from 2967 and we're left with 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 486

Advancing to step 5:
486 can be fit into 518 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Subtracting 486 from 518 leaves us with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 486

On to step 6:
323 divided by 486 is 0 with a remainder of 323.
Record the quotient 0 as the next digit in the result. 
Result so far: 1610.0
Deduct 0 from 323 and we're left with 323.
Append the next digit (1) from the dividend to 323 and continue with: 3231 / 486

Going ahead to step 7:
The number 486 fits into 3231 6 times, leaving a remainder of 315.
The next digit of our result is 6. 
Result so far: 16106.0
Subtract 2916 from 3231 to get 315.
Take the next digit (3) from the dividend and append it to 315, then repeat: 3153 / 486

Advancing to step 8:
If we divide 3153 by 486, we get 6 and a remainder of 237.
The next digit of our result is 6. 
Result so far: 161066.0
Subtract 2916 from 3153 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 9:
486 can be fit into 2370 4 times, resulting in a remainder of 426.
Record the quotient 4 as the next digit in the result. 
Result so far: 161066.4
Subtract 1944 from 2370 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 10:
When dividing 4260 by 486, we get 8 with a remainder of 372.
Use 8 as the next digit of our solution. 
Result so far: 161066.48
The remainder is 372 after subtracting 3888 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 11:
3720 divided by 486 is 7 with a remainder of 318.
Write down 7 as next digit of the result. 
Result so far: 161066.487
Deduct 3402 from 3720 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 12:
486 goes into 3180 6 times with a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 161066.4876
If we take 2916 away from 3180, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 13:
If we divide 2640 by 486, we get 5 and a remainder of 210.
The next digit of our result is 5. 
Result so far: 161066.48765
The remainder is 210 after subtracting 2430 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 14:
If we divide 2100 by 486, we get 4 and a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 161066.487654
If we take 1944 away from 2100, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 15:
486 goes into 1560 3 times with a remainder of 102.
The next digit of our result is 3. 
Result so far: 161066.4876543
If we take 1458 away from 1560, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 16:
When dividing 1020 by 486, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 161066.48765432
Deduct 972 from 1020 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 161066.48765432 with a remainder of 4.8e-08.
