122944 divided by 31 
The aim is to understand the frequency of 31 in 122944.

Advancing to step 1:
1 divided by 31 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 31

Step 2:
31 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 31

Step 3:
31 goes into 122 3 times with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 93 from 122 and we're left with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 31

Step 4:
The number 31 fits into 299 9 times, leaving a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 279 from 299 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 31

Advancing to step 5:
If we divide 204 by 31, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 396.0
Subtract 186 from 204 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 31

Step 6:
31 goes into 184 5 times with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 3965.0
Subtract 155 from 184 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
When dividing 290 by 31, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 3965.9
The remainder is 11 after subtracting 279 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
If we divide 110 by 31, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3965.93
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
170 divided by 31 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3965.935
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 31 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 3965.9354
If we subtract 124 from 150, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
If we divide 260 by 31, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 3965.93548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
31 can be fit into 120 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 3965.935483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
If we divide 270 by 31, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 3965.9354838
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
When dividing 220 by 31, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3965.93548387
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 3965.93548387, with a leftover of 3e-09.
