We divide 64155339 by 78
The aim is to understand the frequency of 78 in 64155339.

Let's proceed to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 78

Moving on to step 2:
If we divide 64 by 78, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 78

On to step 3:
641 divided by 78 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 624 from 641 and we're left with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 78

Advancing to step 4:
175 divided by 78 is 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 82.0
If we take 156 away from 175, we end up with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 78

Step 5:
The number 78 fits into 195 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 822.0
The remainder is 39 after subtracting 156 from 195.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 78

On to step 6:
When dividing 393 by 78, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 8225.0
Subtract 390 from 393 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 78

On to step 7:
78 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 82250.0
Subtracting 0 from 33 leaves us with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 78

Step 8:
The number 78 fits into 339 4 times, leaving a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 822504.0
Deduct 312 from 339 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
If we divide 270 by 78, we get 3 and a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 822504.3
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
78 goes into 360 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 822504.34
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 78, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 822504.346
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
If we divide 120 by 78, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 822504.3461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
The number 78 fits into 420 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 822504.34615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
78 goes into 300 3 times with a remainder of 66.
The next digit of our result is 3. 
Result so far: 822504.346153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 15:
660 divided by 78 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 822504.3461538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 16:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 822504.34615384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 822504.34615384, and the remainder is 4.8e-08.
