756976 divided by 31 
The aim is to understand the frequency of 31 in 756976.

Let's proceed to step 1:
31 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 31

Let's proceed to step 2:
The number 31 fits into 75 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 62 from 75 and we're left with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 31

On to step 3:
31 can be fit into 136 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 124 away from 136, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 31

Moving on to step 4:
31 goes into 129 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 244.0
If we take 124 away from 129, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 31

Step 5:
If we divide 57 by 31, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 2441.0
Subtract 31 from 57 to get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 31

Moving on to step 6:
31 goes into 266 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 24418.0
Subtracting 248 from 266 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
31 goes into 180 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 24418.5
If we subtract 155 from 180, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
31 can be fit into 250 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 24418.58
If we take 248 away from 250, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
31 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 24418.58
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
200 divided by 31 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 24418.5806
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 24418.58064
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 24418.580645
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
31 goes into 50 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 24418.5806451
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
When dividing 190 by 31, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 24418.58064516
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 24418.58064516, with a leftover of 4e-09.
