Let's divide 14103978 by 393
The aim is to understand the frequency of 393 in 14103978.

Let's proceed to step 1:
1 divided by 393 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 393

Going ahead to step 2:
If we divide 14 by 393, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 393

Advancing to step 3:
The number 393 fits into 141 0 times, leaving a remainder of 141.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 141 to get 141.
Grab the next digit (0) from the dividend, add it to 141, then carry on: 1410 / 393

Advancing to step 4:
If we divide 1410 by 393, we get 3 and a remainder of 231.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1179 from 1410, we get 231.
Grab the next digit (3) from the dividend, add it to 231, then carry on: 2313 / 393

Advancing to step 5:
When dividing 2313 by 393, we get 5 with a remainder of 348.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 1965 from 2313, we get 348.
Append the next digit (9) from the dividend to 348 and continue with: 3489 / 393

On to step 6:
If we divide 3489 by 393, we get 8 and a remainder of 345.
The next digit of our result is 8. 
Result so far: 358.0
Subtracting 3144 from 3489 leaves us with 345.
Take the next digit (7) from the dividend and append it to 345, then repeat: 3457 / 393

Advancing to step 7:
If we divide 3457 by 393, we get 8 and a remainder of 313.
Put 8 as the next digit of the answer. 
Result so far: 3588.0
If we subtract 3144 from 3457, we get 313.
Take the next digit (8) from the dividend and append it to 313, then repeat: 3138 / 393

Step 8:
If we divide 3138 by 393, we get 7 and a remainder of 387.
The next digit of our result is 7. 
Result so far: 35887.0
Deduct 2751 from 3138 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 9:
3870 divided by 393 is 9 with a remainder of 333.
The number 9 becomes the next digit in our result. 
Result so far: 35887.9
Deduct 3537 from 3870 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 10:
393 goes into 3330 8 times with a remainder of 186.
The number 8 becomes the next digit in our result. 
Result so far: 35887.98
The remainder is 186 after subtracting 3144 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 11:
If we divide 1860 by 393, we get 4 and a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 35887.984
Subtract 1572 from 1860 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
2880 divided by 393 is 7 with a remainder of 129.
Write down 7 as next digit of the result. 
Result so far: 35887.9847
Subtracting 2751 from 2880 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 13:
393 can be fit into 1290 3 times, resulting in a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 35887.98473
If we take 1179 away from 1290, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 14:
1110 divided by 393 is 2 with a remainder of 324.
The next digit of our result is 2. 
Result so far: 35887.984732
Subtracting 786 from 1110 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 15:
393 can be fit into 3240 8 times, resulting in a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 35887.9847328
Subtract 3144 from 3240 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
If we divide 960 by 393, we get 2 and a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 35887.98473282
Subtracting 786 from 960 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final outcome is 35887.98473282, with a leftover of 1.74e-07.
