Let's divide 37839 by 25
The aim is to understand the frequency of 25 in 37839.

Step 1:
3 divided by 25 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 25

On to step 2:
37 divided by 25 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 25 from 37 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 25

On to step 3:
If we divide 128 by 25, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 125 from 128, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 25

Step 4:
25 can be fit into 33 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtract 25 from 33 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 25

Going ahead to step 5:
89 divided by 25 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 1513.0
If we take 75 away from 89, we end up 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.

Going ahead to step 6:
The number 25 fits into 140 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1513.5
Subtract 125 from 140 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
When dividing 150 by 25, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 1513.56
If we subtract 150 from 150, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1513.56
Subtracting 0 from 0 leaves us 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.

Step 9:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1513.56
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1513.56, with a leftover of 0.0.
