31347754 ÷ 139 
The aim is to understand the frequency of 139 in 31347754.

Step 1:
If we divide 3 by 139, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 139

Moving on to step 2:
If we divide 31 by 139, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 139

Going ahead to step 3:
139 can be fit into 313 2 times, resulting in a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 278 from 313 leaves us with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 139

On to step 4:
If we divide 354 by 139, we get 2 and a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 278 from 354 to get 76.
Bring next digit (7) of the dividend behind the 76 and repeat the process: 767 / 139

Let's proceed to step 5:
The number 139 fits into 767 5 times, leaving a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
Deduct 695 from 767 and we're left with 72.
Grab the next digit (7) from the dividend, add it to 72, then carry on: 727 / 139

Going ahead to step 6:
When dividing 727 by 139, we get 5 with a remainder of 32.
The next digit of our result is 5. 
Result so far: 2255.0
The remainder is 32 after subtracting 695 from 727.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 139

Moving on to step 7:
325 divided by 139 is 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 22552.0
Subtracting 278 from 325 leaves us with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 139

On to step 8:
474 divided by 139 is 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 225523.0
The remainder is 57 after subtracting 417 from 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
If we divide 570 by 139, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 225523.4
Deduct 556 from 570 and we're left with 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 10:
The number 139 fits into 140 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 225523.41
Subtracting 139 from 140 leaves us 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 11:
If we divide 10 by 139, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 225523.41
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.

On to step 12:
139 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 225523.41
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 225523.41 with a remaining 0.001.
