67344478 ÷ 31 
The aim is to understand the frequency of 31 in 67344478.

Going ahead to step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 31

Going ahead to step 2:
When dividing 67 by 31, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 62 from 67 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 31

Moving on to step 3:
When dividing 53 by 31, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 31 from 53, we get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 31

Advancing to step 4:
224 divided by 31 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Deduct 217 from 224 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 31

Let's proceed to step 5:
31 can be fit into 74 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 2172.0
If we take 62 away from 74, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 31

On to step 6:
The number 31 fits into 124 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 21724.0
Subtract 124 from 124 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 31

Step 7:
When dividing 7 by 31, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 217240.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 31

Moving on to step 8:
31 goes into 78 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2172402.0
If we subtract 62 from 78, we 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.

Moving on to step 9:
If we divide 160 by 31, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 2172402.5
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 2172402.51
Subtracting 31 from 50 leaves us with 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 11:
The number 31 fits into 190 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2172402.516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 2172402.5161
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
If we divide 90 by 31, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2172402.51612
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 2172402.516129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 15:
When dividing 10 by 31, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2172402.516129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
When dividing 100 by 31, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 2172402.51612903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 2172402.51612903 with a remaining 7e-09.
