Let's divide 978106 by 78
The aim is to understand the frequency of 78 in 978106.

Going ahead to step 1:
9 divided by 78 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 78

Advancing to step 2:
78 goes into 97 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 78 from 97 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 78

Step 3:
78 can be fit into 198 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 42 after subtracting 156 from 198.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 78

On to step 4:
When dividing 421 by 78, we get 5 with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we subtract 390 from 421, we get 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 78

On to step 5:
310 divided by 78 is 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 1253.0
Subtracting 234 from 310 leaves us with 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 78

Step 6:
The number 78 fits into 766 9 times, leaving a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 12539.0
If we subtract 702 from 766, 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.

Advancing to step 7:
640 divided by 78 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12539.8
Subtract 624 from 640 to 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.

Going ahead to step 8:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12539.82
If we take 156 away from 160, we end up 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.

Advancing to step 9:
78 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12539.82
Subtracting 0 from 40 leaves us 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.

Step 10:
400 divided by 78 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 12539.8205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 78, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 12539.82051
Subtract 78 from 100 to 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.

Let's proceed to step 12:
78 goes into 220 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 12539.820512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
When dividing 640 by 78, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12539.8205128
Subtract 624 from 640 to 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.

Step 14:
If we divide 160 by 78, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12539.82051282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 12539.82051282 with a remainder of 4e-09.
