Let's divide 13889536 by 647
The aim is to understand the frequency of 647 in 13889536.

Advancing to step 1:
1 divided by 647 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 647

Advancing to step 2:
If we divide 13 by 647, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 647

Step 3:
The number 647 fits into 138 0 times, leaving a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Bring next digit (8) of the dividend behind the 138 and repeat the process: 1388 / 647

Going ahead to step 4:
When dividing 1388 by 647, we get 2 with a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1294 from 1388 leaves us with 94.
Take the next digit (9) from the dividend and append it to 94, then repeat: 949 / 647

Let's proceed to step 5:
If we divide 949 by 647, we get 1 and a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 647 from 949 and we're left with 302.
Grab the next digit (5) from the dividend, add it to 302, then carry on: 3025 / 647

On to step 6:
The number 647 fits into 3025 4 times, leaving a remainder of 437.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we subtract 2588 from 3025, we get 437.
Grab the next digit (3) from the dividend, add it to 437, then carry on: 4373 / 647

Let's proceed to step 7:
If we divide 4373 by 647, we get 6 and a remainder of 491.
The next digit of our result is 6. 
Result so far: 2146.0
Subtracting 3882 from 4373 leaves us with 491.
Grab the next digit (6) from the dividend, add it to 491, then carry on: 4916 / 647

On to step 8:
647 goes into 4916 7 times with a remainder of 387.
Put 7 as the next digit of the answer. 
Result so far: 21467.0
Deduct 4529 from 4916 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 9:
3870 divided by 647 is 5 with a remainder of 635.
Put 5 as the next digit of the answer. 
Result so far: 21467.5
If we take 3235 away from 3870, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 10:
6350 divided by 647 is 9 with a remainder of 527.
Record the quotient 9 as the next digit in the result. 
Result so far: 21467.59
Subtracting 5823 from 6350 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Going ahead to step 11:
The number 647 fits into 5270 8 times, leaving a remainder of 94.
Put 8 as the next digit of the answer. 
Result so far: 21467.598
Subtract 5176 from 5270 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 12:
647 can be fit into 940 1 times, resulting in a remainder of 293.
Put 1 as the next digit of the answer. 
Result so far: 21467.5981
Deduct 647 from 940 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 13:
2930 divided by 647 is 4 with a remainder of 342.
Put 4 as the next digit of the answer. 
Result so far: 21467.59814
Subtracting 2588 from 2930 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 14:
If we divide 3420 by 647, we get 5 and a remainder of 185.
The next digit of our result is 5. 
Result so far: 21467.598145
Subtract 3235 from 3420 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 15:
When dividing 1850 by 647, we get 2 with a remainder of 556.
The next digit of our result is 2. 
Result so far: 21467.5981452
Subtract 1294 from 1850 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 16:
5560 divided by 647 is 8 with a remainder of 384.
Write down 8 as next digit of the result. 
Result so far: 21467.59814528
If we subtract 5176 from 5560, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 21467.59814528, with a leftover of 3.84e-07.
