45373713 divided by 331 
The aim is to understand the frequency of 331 in 45373713.

Let's proceed to step 1:
4 divided by 331 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 331

Step 2:
When dividing 45 by 331, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 331

Advancing to step 3:
453 divided by 331 is 1 with a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 331 from 453, we get 122.
Append the next digit (7) from the dividend to 122 and continue with: 1227 / 331

Moving on to step 4:
If we divide 1227 by 331, we get 3 and a remainder of 234.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 993 away from 1227, we end up with 234.
Bring next digit (3) of the dividend behind the 234 and repeat the process: 2343 / 331

Let's proceed to step 5:
2343 divided by 331 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 2317 from 2343 to get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 331

Step 6:
If we divide 267 by 331, we get 0 and a remainder of 267.
Record the quotient 0 as the next digit in the result. 
Result so far: 1370.0
Deduct 0 from 267 and we're left with 267.
Take the next digit (1) from the dividend and append it to 267, then repeat: 2671 / 331

Advancing to step 7:
331 goes into 2671 8 times with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 13708.0
Subtracting 2648 from 2671 leaves us with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 331

Moving on to step 8:
When dividing 233 by 331, we get 0 with a remainder of 233.
Use 0 as the next digit of our solution. 
Result so far: 137080.0
If we subtract 0 from 233, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 9:
If we divide 2330 by 331, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 137080.7
If we take 2317 away from 2330, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
If we divide 130 by 331, we get 0 and a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 137080.7
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
331 can be fit into 1300 3 times, resulting in a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 137080.703
Subtract 993 from 1300 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 12:
The number 331 fits into 3070 9 times, leaving a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 137080.7039
The remainder is 91 after subtracting 2979 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 13:
When dividing 910 by 331, we get 2 with a remainder of 248.
The next digit of our result is 2. 
Result so far: 137080.70392
Deduct 662 from 910 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
2480 divided by 331 is 7 with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 137080.703927
Deduct 2317 from 2480 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 15:
331 can be fit into 1630 4 times, resulting in a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 137080.7039274
Subtract 1324 from 1630 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 16:
When dividing 3060 by 331, we get 9 with a remainder of 81.
The next digit of our result is 9. 
Result so far: 137080.70392749
Subtract 2979 from 3060 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

In conclusion, the division gives 137080.70392749 with a balance of 8.1e-08.
