We divide 38685978 by 543
The aim is to understand the frequency of 543 in 38685978.

Step 1:
3 divided by 543 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 543

Let's proceed to step 2:
The number 543 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 543

Step 3:
If we divide 386 by 543, we get 0 and a remainder of 386.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 386, we end up with 386.
Bring next digit (8) of the dividend behind the 386 and repeat the process: 3868 / 543

Step 4:
543 goes into 3868 7 times with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 3801 away from 3868, we end up with 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 543

Going ahead to step 5:
543 can be fit into 675 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtract 543 from 675 to get 132.
Grab the next digit (9) from the dividend, add it to 132, then carry on: 1329 / 543

Going ahead to step 6:
The number 543 fits into 1329 2 times, leaving a remainder of 243.
Record the quotient 2 as the next digit in the result. 
Result so far: 712.0
Deduct 1086 from 1329 and we're left with 243.
Include the next digit (7) from the dividend after 243, then repeat: 2437 / 543

On to step 7:
543 can be fit into 2437 4 times, resulting in a remainder of 265.
The next digit of our result is 4. 
Result so far: 7124.0
Subtracting 2172 from 2437 leaves us with 265.
Bring next digit (8) of the dividend behind the 265 and repeat the process: 2658 / 543

Going ahead to step 8:
The number 543 fits into 2658 4 times, leaving a remainder of 486.
The next digit of our result is 4. 
Result so far: 71244.0
Subtracting 2172 from 2658 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 9:
The number 543 fits into 4860 8 times, leaving a remainder of 516.
Record the quotient 8 as the next digit in the result. 
Result so far: 71244.8
The remainder is 516 after subtracting 4344 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 10:
When dividing 5160 by 543, we get 9 with a remainder of 273.
The next digit of our result is 9. 
Result so far: 71244.89
If we take 4887 away from 5160, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 11:
543 can be fit into 2730 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 71244.895
The remainder is 15 after subtracting 2715 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
If we divide 150 by 543, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 71244.895
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
543 goes into 1500 2 times with a remainder of 414.
Put 2 as the next digit of the answer. 
Result so far: 71244.89502
The remainder is 414 after subtracting 1086 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 14:
If we divide 4140 by 543, we get 7 and a remainder of 339.
The next digit of our result is 7. 
Result so far: 71244.895027
Deduct 3801 from 4140 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 15:
543 can be fit into 3390 6 times, resulting in a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 71244.8950276
Subtract 3258 from 3390 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 16:
When dividing 1320 by 543, we get 2 with a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 71244.89502762
Subtract 1086 from 1320 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

After the division, we end up with 71244.89502762 and a remainder of 2.34e-07.
