16159473 ÷ 639 
The aim is to understand the frequency of 639 in 16159473.

Step 1:
The number 639 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 639

On to step 2:
The number 639 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 639

Going ahead to step 3:
When dividing 161 by 639, we get 0 with a remainder of 161.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 161 leaves us with 161.
Grab the next digit (5) from the dividend, add it to 161, then carry on: 1615 / 639

Let's proceed to step 4:
When dividing 1615 by 639, we get 2 with a remainder of 337.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1278 from 1615 leaves us with 337.
Append the next digit (9) from the dividend to 337 and continue with: 3379 / 639

Moving on to step 5:
If we divide 3379 by 639, we get 5 and a remainder of 184.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 3195 from 3379 to get 184.
Bring next digit (4) of the dividend behind the 184 and repeat the process: 1844 / 639

Let's proceed to step 6:
639 can be fit into 1844 2 times, resulting in a remainder of 566.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
If we take 1278 away from 1844, we end up with 566.
Bring next digit (7) of the dividend behind the 566 and repeat the process: 5667 / 639

Let's proceed to step 7:
639 goes into 5667 8 times with a remainder of 555.
The next digit of our result is 8. 
Result so far: 2528.0
The remainder is 555 after subtracting 5112 from 5667.
Append the next digit (3) from the dividend to 555 and continue with: 5553 / 639

Advancing to step 8:
When dividing 5553 by 639, we get 8 with a remainder of 441.
Write down 8 as next digit of the result. 
Result so far: 25288.0
Subtract 5112 from 5553 to get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 9:
If we divide 4410 by 639, we get 6 and a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 25288.6
The remainder is 576 after subtracting 3834 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 10:
When dividing 5760 by 639, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 25288.69
Subtract 5751 from 5760 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
When dividing 90 by 639, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 25288.69
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
900 divided by 639 is 1 with a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 25288.6901
Deduct 639 from 900 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 13:
639 goes into 2610 4 times with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 25288.69014
Deduct 2556 from 2610 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
639 can be fit into 540 0 times, resulting in a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 25288.69014
Deduct 0 from 540 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 15:
The number 639 fits into 5400 8 times, leaving a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 25288.6901408
Deduct 5112 from 5400 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 16:
639 can be fit into 2880 4 times, resulting in a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 25288.69014084
Subtract 2556 from 2880 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

In conclusion, the division gives 25288.69014084 with a balance of 3.24e-07.
