25178017 divided by 83 
The aim is to understand the frequency of 83 in 25178017.

On to step 1:
The number 83 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 83

On to step 2:
25 divided by 83 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 83

Moving on to step 3:
83 goes into 251 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 249 away from 251, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 83

Going ahead to step 4:
27 divided by 83 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 83

Going ahead to step 5:
When dividing 278 by 83, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 303.0
Deduct 249 from 278 and we're left with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 83

Going ahead to step 6:
83 goes into 290 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 3033.0
The remainder is 41 after subtracting 249 from 290.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 83

Going ahead to step 7:
When dividing 411 by 83, we get 4 with a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 30334.0
Subtracting 332 from 411 leaves us with 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 83

Going ahead to step 8:
The number 83 fits into 797 9 times, leaving a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 303349.0
The remainder is 50 after subtracting 747 from 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 83 fits into 500 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 303349.6
If we subtract 498 from 500, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
The number 83 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 303349.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 83, we get 2 and a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 303349.602
If we subtract 166 from 200, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
83 goes into 340 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 303349.6024
Subtracting 332 from 340 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
If we divide 80 by 83, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 303349.6024
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
The number 83 fits into 800 9 times, leaving a remainder of 53.
The next digit of our result is 9. 
Result so far: 303349.602409
If we subtract 747 from 800, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 15:
83 goes into 530 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 303349.6024096
If we subtract 498 from 530, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
320 divided by 83 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 303349.60240963
Subtract 249 from 320 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.
