We look at the division of 56628020 by 647 
The aim is to understand the frequency of 647 in 56628020.

Step 1:
5 divided by 647 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 647

Moving on to step 2:
56 divided by 647 is 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 647

Moving on to step 3:
If we divide 566 by 647, we get 0 and a remainder of 566.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 566 leaves us with 566.
Grab the next digit (2) from the dividend, add it to 566, then carry on: 5662 / 647

On to step 4:
5662 divided by 647 is 8 with a remainder of 486.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5176 from 5662 leaves us with 486.
Append the next digit (8) from the dividend to 486 and continue with: 4868 / 647

On to step 5:
647 can be fit into 4868 7 times, resulting in a remainder of 339.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 4529 away from 4868, we end up with 339.
Fetch the next digit (0) from the dividend, attach it to 339 and continue: 3390 / 647

On to step 6:
647 goes into 3390 5 times with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 875.0
Subtract 3235 from 3390 to get 155.
Bring next digit (2) of the dividend behind the 155 and repeat the process: 1552 / 647

Step 7:
647 can be fit into 1552 2 times, resulting in a remainder of 258.
The number 2 becomes the next digit in our result. 
Result so far: 8752.0
If we take 1294 away from 1552, we end up with 258.
Bring next digit (0) of the dividend behind the 258 and repeat the process: 2580 / 647

On to step 8:
When dividing 2580 by 647, we get 3 with a remainder of 639.
Put 3 as the next digit of the answer. 
Result so far: 87523.0
If we take 1941 away from 2580, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

On to step 9:
The number 647 fits into 6390 9 times, leaving a remainder of 567.
Record the quotient 9 as the next digit in the result. 
Result so far: 87523.9
If we take 5823 away from 6390, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 10:
647 can be fit into 5670 8 times, resulting in a remainder of 494.
Record the quotient 8 as the next digit in the result. 
Result so far: 87523.98
If we take 5176 away from 5670, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 11:
647 can be fit into 4940 7 times, resulting in a remainder of 411.
Record the quotient 7 as the next digit in the result. 
Result so far: 87523.987
If we take 4529 away from 4940, we end up with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 12:
647 can be fit into 4110 6 times, resulting in a remainder of 228.
Use 6 as the next digit of our solution. 
Result so far: 87523.9876
If we subtract 3882 from 4110, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 13:
647 goes into 2280 3 times with a remainder of 339.
Use 3 as the next digit of our solution. 
Result so far: 87523.98763
If we subtract 1941 from 2280, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 14:
The number 647 fits into 3390 5 times, leaving a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 87523.987635
If we take 3235 away from 3390, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 15:
647 goes into 1550 2 times with a remainder of 256.
The next digit of our result is 2. 
Result so far: 87523.9876352
Subtracting 1294 from 1550 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
647 goes into 2560 3 times with a remainder of 619.
Put 3 as the next digit of the answer. 
Result so far: 87523.98763523
Subtracting 1941 from 2560 leaves us with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

The quotient of the division is 87523.98763523, and the remainder is 6.19e-07.
