37160461 divided by 321 
The aim is to understand the frequency of 321 in 37160461.

On to step 1:
321 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 321

On to step 2:
If we divide 37 by 321, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 321

Moving on to step 3:
The number 321 fits into 371 1 times, leaving a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 321 from 371 to get 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 321

On to step 4:
When dividing 506 by 321, we get 1 with a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 321 from 506 and we're left with 185.
Append the next digit (0) from the dividend to 185 and continue with: 1850 / 321

Step 5:
When dividing 1850 by 321, we get 5 with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we take 1605 away from 1850, we end up with 245.
Fetch the next digit (4) from the dividend, attach it to 245 and continue: 2454 / 321

Let's proceed to step 6:
When dividing 2454 by 321, we get 7 with a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 1157.0
The remainder is 207 after subtracting 2247 from 2454.
Take the next digit (6) from the dividend and append it to 207, then repeat: 2076 / 321

Moving on to step 7:
The number 321 fits into 2076 6 times, leaving a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 11576.0
Subtract 1926 from 2076 to get 150.
Bring next digit (1) of the dividend behind the 150 and repeat the process: 1501 / 321

Going ahead to step 8:
1501 divided by 321 is 4 with a remainder of 217.
The next digit of our result is 4. 
Result so far: 115764.0
Deduct 1284 from 1501 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 9:
321 goes into 2170 6 times with a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 115764.6
Deduct 1926 from 2170 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 10:
321 can be fit into 2440 7 times, resulting in a remainder of 193.
The number 7 becomes the next digit in our result. 
Result so far: 115764.67
Deduct 2247 from 2440 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 11:
321 can be fit into 1930 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 115764.676
The remainder is 4 after subtracting 1926 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 321, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 115764.676
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
321 can be fit into 400 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 115764.67601
If we subtract 321 from 400, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 14:
If we divide 790 by 321, we get 2 and a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 115764.676012
Subtract 642 from 790 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
When dividing 1480 by 321, we get 4 with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 115764.6760124
Deduct 1284 from 1480 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 16:
The number 321 fits into 1960 6 times, leaving a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 115764.67601246
Subtract 1926 from 1960 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 115764.67601246 with a balance of 3.4e-08.
