We're dividing 42527092 by 639 
The aim is to understand the frequency of 639 in 42527092.

On to step 1:
When dividing 4 by 639, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 639

Step 2:
639 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 639

Let's proceed to step 3:
If we divide 425 by 639, we get 0 and a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 425, we end up with 425.
Bring next digit (2) of the dividend behind the 425 and repeat the process: 4252 / 639

Going ahead to step 4:
4252 divided by 639 is 6 with a remainder of 418.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 418 after subtracting 3834 from 4252.
Take the next digit (7) from the dividend and append it to 418, then repeat: 4187 / 639

Advancing to step 5:
639 can be fit into 4187 6 times, resulting in a remainder of 353.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
The remainder is 353 after subtracting 3834 from 4187.
Take the next digit (0) from the dividend and append it to 353, then repeat: 3530 / 639

Step 6:
3530 divided by 639 is 5 with a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 665.0
Subtracting 3195 from 3530 leaves us with 335.
Include the next digit (9) from the dividend after 335, then repeat: 3359 / 639

On to step 7:
The number 639 fits into 3359 5 times, leaving a remainder of 164.
The next digit of our result is 5. 
Result so far: 6655.0
If we subtract 3195 from 3359, we get 164.
Append the next digit (2) from the dividend to 164 and continue with: 1642 / 639

Let's proceed to step 8:
The number 639 fits into 1642 2 times, leaving a remainder of 364.
The number 2 becomes the next digit in our result. 
Result so far: 66552.0
If we subtract 1278 from 1642, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 9:
639 can be fit into 3640 5 times, resulting in a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 66552.5
Subtract 3195 from 3640 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 10:
If we divide 4450 by 639, we get 6 and a remainder of 616.
Put 6 as the next digit of the answer. 
Result so far: 66552.56
Deduct 3834 from 4450 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 11:
If we divide 6160 by 639, we get 9 and a remainder of 409.
Use 9 as the next digit of our solution. 
Result so far: 66552.569
If we take 5751 away from 6160, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 12:
639 goes into 4090 6 times with a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 66552.5696
The remainder is 256 after subtracting 3834 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
639 goes into 2560 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 66552.56964
The remainder is 4 after subtracting 2556 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
If we divide 40 by 639, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 66552.56964
If we take 0 away from 40, 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.

Step 15:
The number 639 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 66552.56964
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 66552.56964 with a balance of 4e-06.
