We divide 51726 by 78
The aim is to understand the frequency of 78 in 51726.

Moving on to step 1:
When dividing 5 by 78, we get 0 with 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

Step 2:
78 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 78

Moving on to step 3:
78 goes into 517 6 times with a remainder of 49.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 468 from 517, we get 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 78

Going ahead to step 4:
When dividing 492 by 78, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 468 from 492 leaves us with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 78

Advancing to step 5:
When dividing 246 by 78, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 663.0
The remainder is 12 after subtracting 234 from 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 6:
78 can be fit into 120 1 times, resulting in a remainder of 42.
The next digit of our result is 1. 
Result so far: 663.1
If we take 78 away from 120, we end up 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.

Moving on to step 7:
If we divide 420 by 78, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 663.15
If we subtract 390 from 420, we 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.

On to step 8:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 663.153
Deduct 234 from 300 and we're left 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.

Going ahead to step 9:
If we divide 660 by 78, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 663.1538
If we subtract 624 from 660, 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.

Step 10:
78 goes into 360 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 663.15384
If we subtract 312 from 360, we 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.

Going ahead to step 11:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 663.153846
If we take 468 away from 480, we end up with 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:
When dividing 120 by 78, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 663.1538461
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.

Moving on to step 13:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 663.15384615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 663.15384615, and the remainder is 3e-08.
