25999214 ÷ 139 
The aim is to understand the frequency of 139 in 25999214.

Advancing to step 1:
If we divide 2 by 139, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 139

Going ahead to step 2:
139 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 139

Step 3:
139 can be fit into 259 1 times, resulting in a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 139 from 259 leaves us with 120.
Grab the next digit (9) from the dividend, add it to 120, then carry on: 1209 / 139

Advancing to step 4:
139 can be fit into 1209 8 times, resulting in a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 97 after subtracting 1112 from 1209.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 139

On to step 5:
979 divided by 139 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 187.0
If we subtract 973 from 979, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 139

Moving on to step 6:
When dividing 62 by 139, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 1870.0
Subtracting 0 from 62 leaves us with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 139

Let's proceed to step 7:
621 divided by 139 is 4 with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 18704.0
Deduct 556 from 621 and we're left with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 139

Advancing to step 8:
When dividing 654 by 139, we get 4 with a remainder of 98.
The next digit of our result is 4. 
Result so far: 187044.0
If we subtract 556 from 654, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 9:
When dividing 980 by 139, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 187044.7
The remainder is 7 after subtracting 973 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
If we divide 70 by 139, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 187044.7
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
If we divide 700 by 139, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 187044.705
The remainder is 5 after subtracting 695 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 139 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 187044.705
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 139, we get 3 with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 187044.70503
If we take 417 away from 500, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 14:
When dividing 830 by 139, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 187044.705035
Deduct 695 from 830 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 15:
139 goes into 1350 9 times with a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 187044.7050359
If we subtract 1251 from 1350, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 16:
139 can be fit into 990 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 187044.70503597
If we take 973 away from 990, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 187044.70503597, and the remainder is 1.7e-08.
