We divide 27722508 by 639
The aim is to understand the frequency of 639 in 27722508.

Advancing to step 1:
2 divided by 639 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 639

On to step 2:
27 divided by 639 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 639

Going ahead to step 3:
If we divide 277 by 639, we get 0 and a remainder of 277.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 277 after subtracting 0 from 277.
Bring next digit (2) of the dividend behind the 277 and repeat the process: 2772 / 639

Step 4:
When dividing 2772 by 639, we get 4 with a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2556 from 2772, we get 216.
Grab the next digit (2) from the dividend, add it to 216, then carry on: 2162 / 639

On to step 5:
639 can be fit into 2162 3 times, resulting in a remainder of 245.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 1917 from 2162 and we're left with 245.
Append the next digit (5) from the dividend to 245 and continue with: 2455 / 639

Moving on to step 6:
If we divide 2455 by 639, we get 3 and a remainder of 538.
The next digit of our result is 3. 
Result so far: 433.0
If we take 1917 away from 2455, we end up with 538.
Grab the next digit (0) from the dividend, add it to 538, then carry on: 5380 / 639

Step 7:
639 goes into 5380 8 times with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 4338.0
Subtracting 5112 from 5380 leaves us with 268.
Fetch the next digit (8) from the dividend, attach it to 268 and continue: 2688 / 639

Going ahead to step 8:
639 can be fit into 2688 4 times, resulting in a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 43384.0
Subtracting 2556 from 2688 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 9:
The number 639 fits into 1320 2 times, leaving a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 43384.2
Subtract 1278 from 1320 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
If we divide 420 by 639, we get 0 and a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 43384.2
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 11:
The number 639 fits into 4200 6 times, leaving a remainder of 366.
The number 6 becomes the next digit in our result. 
Result so far: 43384.206
The remainder is 366 after subtracting 3834 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 12:
When dividing 3660 by 639, we get 5 with a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 43384.2065
If we subtract 3195 from 3660, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 13:
4650 divided by 639 is 7 with a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 43384.20657
Subtract 4473 from 4650 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 14:
The number 639 fits into 1770 2 times, leaving a remainder of 492.
Write down 2 as next digit of the result. 
Result so far: 43384.206572
The remainder is 492 after subtracting 1278 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 15:
639 goes into 4920 7 times with a remainder of 447.
The next digit of our result is 7. 
Result so far: 43384.2065727
If we take 4473 away from 4920, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 16:
639 goes into 4470 6 times with a remainder of 636.
Record the quotient 6 as the next digit in the result. 
Result so far: 43384.20657276
The remainder is 636 after subtracting 3834 from 4470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 43384.20657276, with a leftover of 6.36e-07.
