We divide 57745661 by 321
The aim is to understand the frequency of 321 in 57745661.

Moving on to step 1:
When dividing 5 by 321, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 321

Advancing to step 2:
If we divide 57 by 321, we get 0 and a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 321

Let's proceed to step 3:
If we divide 577 by 321, we get 1 and a remainder of 256.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 321 from 577, we get 256.
Take the next digit (4) from the dividend and append it to 256, then repeat: 2564 / 321

Let's proceed to step 4:
321 goes into 2564 7 times with a remainder of 317.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 2247 from 2564 leaves us with 317.
Grab the next digit (5) from the dividend, add it to 317, then carry on: 3175 / 321

Let's proceed to step 5:
When dividing 3175 by 321, we get 9 with a remainder of 286.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
The remainder is 286 after subtracting 2889 from 3175.
Bring next digit (6) of the dividend behind the 286 and repeat the process: 2866 / 321

On to step 6:
When dividing 2866 by 321, we get 8 with a remainder of 298.
Record the quotient 8 as the next digit in the result. 
Result so far: 1798.0
If we subtract 2568 from 2866, we get 298.
Bring next digit (6) of the dividend behind the 298 and repeat the process: 2986 / 321

Let's proceed to step 7:
If we divide 2986 by 321, we get 9 and a remainder of 97.
Record the quotient 9 as the next digit in the result. 
Result so far: 17989.0
Subtracting 2889 from 2986 leaves us with 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 321

Going ahead to step 8:
321 goes into 971 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 179893.0
Subtracting 963 from 971 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 321, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 179893.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
When dividing 800 by 321, we get 2 with a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 179893.02
Subtract 642 from 800 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 11:
When dividing 1580 by 321, we get 4 with a remainder of 296.
The next digit of our result is 4. 
Result so far: 179893.024
Deduct 1284 from 1580 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 12:
If we divide 2960 by 321, we get 9 and a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 179893.0249
If we subtract 2889 from 2960, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 13:
When dividing 710 by 321, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 179893.02492
Deduct 642 from 710 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
When dividing 680 by 321, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 179893.024922
Subtracting 642 from 680 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 179893.024922 with a remainder of 3.8e-06.
