Let's divide 28424038 by 639
The aim is to understand the frequency of 639 in 28424038.

Step 1:
If we divide 2 by 639, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 639

On to step 2:
When dividing 28 by 639, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 639

Step 3:
639 can be fit into 284 0 times, resulting in a remainder of 284.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 284, we get 284.
Include the next digit (2) from the dividend after 284, then repeat: 2842 / 639

Going ahead to step 4:
If we divide 2842 by 639, we get 4 and a remainder of 286.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 2556 from 2842 to get 286.
Append the next digit (4) from the dividend to 286 and continue with: 2864 / 639

Let's proceed to step 5:
When dividing 2864 by 639, we get 4 with a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 2556 from 2864 and we're left with 308.
Take the next digit (0) from the dividend and append it to 308, then repeat: 3080 / 639

Advancing to step 6:
3080 divided by 639 is 4 with a remainder of 524.
The next digit of our result is 4. 
Result so far: 444.0
Deduct 2556 from 3080 and we're left with 524.
Append the next digit (3) from the dividend to 524 and continue with: 5243 / 639

Step 7:
The number 639 fits into 5243 8 times, leaving a remainder of 131.
Put 8 as the next digit of the answer. 
Result so far: 4448.0
The remainder is 131 after subtracting 5112 from 5243.
Take the next digit (8) from the dividend and append it to 131, then repeat: 1318 / 639

Let's proceed to step 8:
The number 639 fits into 1318 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 44482.0
If we take 1278 away from 1318, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
When dividing 400 by 639, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 44482.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
639 goes into 4000 6 times with a remainder of 166.
Put 6 as the next digit of the answer. 
Result so far: 44482.06
The remainder is 166 after subtracting 3834 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 11:
639 can be fit into 1660 2 times, resulting in a remainder of 382.
Record the quotient 2 as the next digit in the result. 
Result so far: 44482.062
If we take 1278 away from 1660, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 12:
When dividing 3820 by 639, we get 5 with a remainder of 625.
The next digit of our result is 5. 
Result so far: 44482.0625
Deduct 3195 from 3820 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 13:
When dividing 6250 by 639, we get 9 with a remainder of 499.
Put 9 as the next digit of the answer. 
Result so far: 44482.06259
The remainder is 499 after subtracting 5751 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 14:
The number 639 fits into 4990 7 times, leaving a remainder of 517.
Use 7 as the next digit of our solution. 
Result so far: 44482.062597
If we take 4473 away from 4990, we end up with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

On to step 15:
If we divide 5170 by 639, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 44482.0625978
Subtracting 5112 from 5170 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
639 can be fit into 580 0 times, resulting in a remainder of 580.
The next digit of our result is 0. 
Result so far: 44482.0625978
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Our division results in 44482.0625978 with a remaining 5.8e-07.
