975446 ÷ 31 
The aim is to understand the frequency of 31 in 975446.

Going ahead to step 1:
The number 31 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 31

Going ahead to step 2:
31 goes into 97 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 4 after subtracting 93 from 97.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 31

Moving on to step 3:
If we divide 45 by 31, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 31 from 45, we get 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 31

Going ahead to step 4:
When dividing 144 by 31, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
Deduct 124 from 144 and we're left with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 31

Let's proceed to step 5:
When dividing 204 by 31, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 3146.0
Subtracting 186 from 204 leaves us with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 31

Going ahead to step 6:
If we divide 186 by 31, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 31466.0
The remainder is 0 after subtracting 186 from 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 31 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31466.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 31, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31466.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 31466.0 and a remainder of 0.0.
