Let's divide 514972 by 78
The aim is to understand the frequency of 78 in 514972.

Going ahead to step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 78

On to step 2:
If we divide 51 by 78, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 78

Let's proceed to step 3:
If we divide 514 by 78, we get 6 and a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 468 from 514 leaves us with 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 78

Let's proceed to step 4:
78 can be fit into 469 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
The remainder is 1 after subtracting 468 from 469.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 78

On to step 5:
78 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 660.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 78

Step 6:
78 goes into 172 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 6602.0
If we subtract 156 from 172, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 6602.2
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6602.2
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 6602.205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
78 goes into 100 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 6602.2051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
If we divide 220 by 78, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 6602.20512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
78 goes into 640 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 6602.205128
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
160 divided by 78 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 6602.2051282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
78 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 6602.2051282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 6602.2051282, and the remainder is 4e-08.
