We're dividing 73287862 by 639 
The aim is to understand the frequency of 639 in 73287862.

Let's proceed to step 1:
7 divided by 639 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 639

On to step 2:
The number 639 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 639

Step 3:
639 goes into 732 1 times with a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 639 from 732 leaves us with 93.
Include the next digit (8) from the dividend after 93, then repeat: 938 / 639

On to step 4:
639 can be fit into 938 1 times, resulting in a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 299 after subtracting 639 from 938.
Grab the next digit (7) from the dividend, add it to 299, then carry on: 2997 / 639

Advancing to step 5:
When dividing 2997 by 639, we get 4 with a remainder of 441.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 2556 away from 2997, we end up with 441.
Bring next digit (8) of the dividend behind the 441 and repeat the process: 4418 / 639

Moving on to step 6:
639 goes into 4418 6 times with a remainder of 584.
Write down 6 as next digit of the result. 
Result so far: 1146.0
The remainder is 584 after subtracting 3834 from 4418.
Append the next digit (6) from the dividend to 584 and continue with: 5846 / 639

Advancing to step 7:
639 goes into 5846 9 times with a remainder of 95.
Use 9 as the next digit of our solution. 
Result so far: 11469.0
If we take 5751 away from 5846, we end up with 95.
Grab the next digit (2) from the dividend, add it to 95, then carry on: 952 / 639

Moving on to step 8:
639 can be fit into 952 1 times, resulting in a remainder of 313.
Write down 1 as next digit of the result. 
Result so far: 114691.0
If we take 639 away from 952, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 9:
If we divide 3130 by 639, we get 4 and a remainder of 574.
Use 4 as the next digit of our solution. 
Result so far: 114691.4
The remainder is 574 after subtracting 2556 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 10:
639 goes into 5740 8 times with a remainder of 628.
The number 8 becomes the next digit in our result. 
Result so far: 114691.48
If we take 5112 away from 5740, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 11:
When dividing 6280 by 639, we get 9 with a remainder of 529.
Use 9 as the next digit of our solution. 
Result so far: 114691.489
Subtracting 5751 from 6280 leaves us with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 12:
The number 639 fits into 5290 8 times, leaving a remainder of 178.
The next digit of our result is 8. 
Result so far: 114691.4898
The remainder is 178 after subtracting 5112 from 5290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 13:
1780 divided by 639 is 2 with a remainder of 502.
Use 2 as the next digit of our solution. 
Result so far: 114691.48982
Deduct 1278 from 1780 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 14:
When dividing 5020 by 639, we get 7 with a remainder of 547.
The number 7 becomes the next digit in our result. 
Result so far: 114691.489827
Deduct 4473 from 5020 and we're left with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Moving on to step 15:
639 can be fit into 5470 8 times, resulting in a remainder of 358.
The number 8 becomes the next digit in our result. 
Result so far: 114691.4898278
The remainder is 358 after subtracting 5112 from 5470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 16:
3580 divided by 639 is 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 114691.48982785
The remainder is 385 after subtracting 3195 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Our division results in 114691.48982785 with a remaining 3.85e-07.
