We're dividing 43680311 by 647 
The aim is to understand the frequency of 647 in 43680311.

Moving on to step 1:
When dividing 4 by 647, 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.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 647

Moving on to step 2:
43 divided by 647 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 647

On to step 3:
647 can be fit into 436 0 times, resulting in a remainder of 436.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 436 and we're left with 436.
Include the next digit (8) from the dividend after 436, then repeat: 4368 / 647

Moving on to step 4:
647 goes into 4368 6 times with a remainder of 486.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 3882 from 4368 leaves us with 486.
Grab the next digit (0) from the dividend, add it to 486, then carry on: 4860 / 647

Advancing to step 5:
The number 647 fits into 4860 7 times, leaving a remainder of 331.
Write down 7 as next digit of the result. 
Result so far: 67.0
Deduct 4529 from 4860 and we're left with 331.
Bring next digit (3) of the dividend behind the 331 and repeat the process: 3313 / 647

Step 6:
When dividing 3313 by 647, we get 5 with a remainder of 78.
Use 5 as the next digit of our solution. 
Result so far: 675.0
If we take 3235 away from 3313, we end up with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 647

Moving on to step 7:
647 can be fit into 781 1 times, resulting in a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 6751.0
If we take 647 away from 781, we end up with 134.
Take the next digit (1) from the dividend and append it to 134, then repeat: 1341 / 647

On to step 8:
647 can be fit into 1341 2 times, resulting in a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 67512.0
If we take 1294 away from 1341, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
The number 647 fits into 470 0 times, leaving a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 67512.0
The remainder is 470 after subtracting 0 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
The number 647 fits into 4700 7 times, leaving a remainder of 171.
Record the quotient 7 as the next digit in the result. 
Result so far: 67512.07
Deduct 4529 from 4700 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 11:
When dividing 1710 by 647, we get 2 with a remainder of 416.
Record the quotient 2 as the next digit in the result. 
Result so far: 67512.072
If we take 1294 away from 1710, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 12:
If we divide 4160 by 647, we get 6 and a remainder of 278.
The number 6 becomes the next digit in our result. 
Result so far: 67512.0726
The remainder is 278 after subtracting 3882 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 13:
If we divide 2780 by 647, we get 4 and a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 67512.07264
Subtract 2588 from 2780 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
When dividing 1920 by 647, we get 2 with a remainder of 626.
The next digit of our result is 2. 
Result so far: 67512.072642
Subtracting 1294 from 1920 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Moving on to step 15:
If we divide 6260 by 647, we get 9 and a remainder of 437.
Write down 9 as next digit of the result. 
Result so far: 67512.0726429
Subtracting 5823 from 6260 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 16:
4370 divided by 647 is 6 with a remainder of 488.
The next digit of our result is 6. 
Result so far: 67512.07264296
Subtracting 3882 from 4370 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The quotient of the division is 67512.07264296, and the remainder is 4.88e-07.
