Let's divide 19963681 by 393
The aim is to understand the frequency of 393 in 19963681.

Let's proceed to step 1:
393 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 393

Let's proceed to step 2:
When dividing 19 by 393, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 393

Going ahead to step 3:
When dividing 199 by 393, we get 0 with a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 199 after subtracting 0 from 199.
Fetch the next digit (6) from the dividend, attach it to 199 and continue: 1996 / 393

Moving on to step 4:
The number 393 fits into 1996 5 times, leaving a remainder of 31.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 1965 from 1996 to get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 393

Moving on to step 5:
313 divided by 393 is 0 with a remainder of 313.
Put 0 as the next digit of the answer. 
Result so far: 50.0
The remainder is 313 after subtracting 0 from 313.
Grab the next digit (6) from the dividend, add it to 313, then carry on: 3136 / 393

Step 6:
When dividing 3136 by 393, we get 7 with a remainder of 385.
Put 7 as the next digit of the answer. 
Result so far: 507.0
Subtracting 2751 from 3136 leaves us with 385.
Take the next digit (8) from the dividend and append it to 385, then repeat: 3858 / 393

Moving on to step 7:
If we divide 3858 by 393, we get 9 and a remainder of 321.
Write down 9 as next digit of the result. 
Result so far: 5079.0
If we take 3537 away from 3858, we end up with 321.
Grab the next digit (1) from the dividend, add it to 321, then carry on: 3211 / 393

Moving on to step 8:
393 can be fit into 3211 8 times, resulting in a remainder of 67.
Record the quotient 8 as the next digit in the result. 
Result so far: 50798.0
If we take 3144 away from 3211, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
If we divide 670 by 393, we get 1 and a remainder of 277.
Write down 1 as next digit of the result. 
Result so far: 50798.1
Subtracting 393 from 670 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 10:
When dividing 2770 by 393, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 50798.17
If we take 2751 away from 2770, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
If we divide 190 by 393, we get 0 and a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 50798.17
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 12:
393 goes into 1900 4 times with a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 50798.1704
Subtract 1572 from 1900 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 13:
393 can be fit into 3280 8 times, resulting in a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 50798.17048
Subtract 3144 from 3280 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 14:
393 can be fit into 1360 3 times, resulting in a remainder of 181.
The number 3 becomes the next digit in our result. 
Result so far: 50798.170483
If we take 1179 away from 1360, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 15:
393 goes into 1810 4 times with a remainder of 238.
The next digit of our result is 4. 
Result so far: 50798.1704834
Deduct 1572 from 1810 and we're left 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.

Advancing to step 16:
393 goes into 2380 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 50798.17048346
Subtract 2358 from 2380 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 50798.17048346, with a leftover of 2.2e-08.
