We're dividing 10466580 by 393 
The aim is to understand the frequency of 393 in 10466580.

On to step 1:
If we divide 1 by 393, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 393

Step 2:
393 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 393

Moving on to step 3:
When dividing 104 by 393, we get 0 with a remainder of 104.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Grab the next digit (6) from the dividend, add it to 104, then carry on: 1046 / 393

Moving on to step 4:
If we divide 1046 by 393, we get 2 and a remainder of 260.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 260 after subtracting 786 from 1046.
Append the next digit (6) from the dividend to 260 and continue with: 2606 / 393

On to step 5:
The number 393 fits into 2606 6 times, leaving a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 2358 from 2606 and we're left with 248.
Append the next digit (5) from the dividend to 248 and continue with: 2485 / 393

Going ahead to step 6:
2485 divided by 393 is 6 with a remainder of 127.
Use 6 as the next digit of our solution. 
Result so far: 266.0
Deduct 2358 from 2485 and we're left with 127.
Include the next digit (8) from the dividend after 127, then repeat: 1278 / 393

Let's proceed to step 7:
1278 divided by 393 is 3 with a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 2663.0
Deduct 1179 from 1278 and we're left with 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 393

Step 8:
393 can be fit into 990 2 times, resulting in a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 26632.0
Subtracting 786 from 990 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 9:
When dividing 2040 by 393, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 26632.5
If we take 1965 away from 2040, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
When dividing 750 by 393, we get 1 with a remainder of 357.
The next digit of our result is 1. 
Result so far: 26632.51
Deduct 393 from 750 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 11:
When dividing 3570 by 393, we get 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 26632.519
Subtract 3537 from 3570 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 12:
393 goes into 330 0 times with a remainder of 330.
The next digit of our result is 0. 
Result so far: 26632.519
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 13:
393 goes into 3300 8 times with a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 26632.51908
If we take 3144 away from 3300, 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.

Step 14:
393 goes into 1560 3 times with a remainder of 381.
Put 3 as the next digit of the answer. 
Result so far: 26632.519083
Subtracting 1179 from 1560 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 15:
393 can be fit into 3810 9 times, resulting in a remainder of 273.
Use 9 as the next digit of our solution. 
Result so far: 26632.5190839
If we subtract 3537 from 3810, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 16:
2730 divided by 393 is 6 with a remainder of 372.
Record the quotient 6 as the next digit in the result. 
Result so far: 26632.51908396
If we subtract 2358 from 2730, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 26632.51908396 and a remainder of 3.72e-07.
