57079331 divided by 321 
The aim is to understand the frequency of 321 in 57079331.

Going ahead to step 1:
If we divide 5 by 321, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 321

Step 2:
321 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 321

Let's proceed to step 3:
When dividing 570 by 321, we get 1 with a remainder of 249.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 321 from 570 to get 249.
Fetch the next digit (7) from the dividend, attach it to 249 and continue: 2497 / 321

Step 4:
321 can be fit into 2497 7 times, resulting in a remainder of 250.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 2247 from 2497 leaves us with 250.
Grab the next digit (9) from the dividend, add it to 250, then carry on: 2509 / 321

Advancing to step 5:
321 can be fit into 2509 7 times, resulting in a remainder of 262.
The next digit of our result is 7. 
Result so far: 177.0
Subtract 2247 from 2509 to get 262.
Bring next digit (3) of the dividend behind the 262 and repeat the process: 2623 / 321

Let's proceed to step 6:
If we divide 2623 by 321, we get 8 and a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 1778.0
If we subtract 2568 from 2623, we get 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 321

Step 7:
321 goes into 553 1 times with a remainder of 232.
The next digit of our result is 1. 
Result so far: 17781.0
Subtracting 321 from 553 leaves us with 232.
Take the next digit (1) from the dividend and append it to 232, then repeat: 2321 / 321

Moving on to step 8:
321 goes into 2321 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 177817.0
If we take 2247 away from 2321, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
When dividing 740 by 321, we get 2 with a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 177817.2
If we take 642 away from 740, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 10:
When dividing 980 by 321, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 177817.23
The remainder is 17 after subtracting 963 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
If we divide 170 by 321, we get 0 and a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 177817.23
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 12:
321 goes into 1700 5 times with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 177817.2305
If we subtract 1605 from 1700, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 13:
321 can be fit into 950 2 times, resulting in a remainder of 308.
The next digit of our result is 2. 
Result so far: 177817.23052
The remainder is 308 after subtracting 642 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 14:
3080 divided by 321 is 9 with a remainder of 191.
The number 9 becomes the next digit in our result. 
Result so far: 177817.230529
Subtract 2889 from 3080 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 15:
The number 321 fits into 1910 5 times, leaving a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 177817.2305295
Subtracting 1605 from 1910 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 16:
If we divide 3050 by 321, we get 9 and a remainder of 161.
Write down 9 as next digit of the result. 
Result so far: 177817.23052959
Subtracting 2889 from 3050 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

After the division, we end up with 177817.23052959 and a remainder of 1.61e-07.
