We divide 78861828 by 647
The aim is to understand the frequency of 647 in 78861828.

On to step 1:
When dividing 7 by 647, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 647

Moving on to step 2:
When dividing 78 by 647, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (8) from the dividend to 78 and continue with: 788 / 647

Let's proceed to step 3:
647 goes into 788 1 times with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 647 from 788 leaves us with 141.
Grab the next digit (6) from the dividend, add it to 141, then carry on: 1416 / 647

Advancing to step 4:
When dividing 1416 by 647, we get 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1294 from 1416 to get 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 647

Advancing to step 5:
647 can be fit into 1221 1 times, resulting in a remainder of 574.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we subtract 647 from 1221, we get 574.
Bring next digit (8) of the dividend behind the 574 and repeat the process: 5748 / 647

Advancing to step 6:
The number 647 fits into 5748 8 times, leaving a remainder of 572.
The next digit of our result is 8. 
Result so far: 1218.0
If we take 5176 away from 5748, we end up with 572.
Include the next digit (2) from the dividend after 572, then repeat: 5722 / 647

Let's proceed to step 7:
647 can be fit into 5722 8 times, resulting in a remainder of 546.
The number 8 becomes the next digit in our result. 
Result so far: 12188.0
Subtracting 5176 from 5722 leaves us with 546.
Include the next digit (8) from the dividend after 546, then repeat: 5468 / 647

Step 8:
5468 divided by 647 is 8 with a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 121888.0
The remainder is 292 after subtracting 5176 from 5468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 9:
647 can be fit into 2920 4 times, resulting in a remainder of 332.
Write down 4 as next digit of the result. 
Result so far: 121888.4
Deduct 2588 from 2920 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 10:
The number 647 fits into 3320 5 times, leaving a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 121888.45
Deduct 3235 from 3320 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
850 divided by 647 is 1 with a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 121888.451
If we take 647 away from 850, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 12:
When dividing 2030 by 647, we get 3 with a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 121888.4513
Deduct 1941 from 2030 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 13:
The number 647 fits into 890 1 times, leaving a remainder of 243.
Record the quotient 1 as the next digit in the result. 
Result so far: 121888.45131
If we subtract 647 from 890, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 14:
When dividing 2430 by 647, we get 3 with a remainder of 489.
Record the quotient 3 as the next digit in the result. 
Result so far: 121888.451313
The remainder is 489 after subtracting 1941 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Going ahead to step 15:
The number 647 fits into 4890 7 times, leaving a remainder of 361.
Record the quotient 7 as the next digit in the result. 
Result so far: 121888.4513137
If we subtract 4529 from 4890, we get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 16:
The number 647 fits into 3610 5 times, leaving a remainder of 375.
The next digit of our result is 5. 
Result so far: 121888.45131375
The remainder is 375 after subtracting 3235 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Our division results in 121888.45131375 with a remaining 3.75e-07.
