We divide 843127 by 78
The aim is to understand the frequency of 78 in 843127.

Step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 78

Advancing to step 2:
When dividing 84 by 78, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 78 from 84, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 78

Moving on to step 3:
When dividing 63 by 78, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 63, we get 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 78

Step 4:
631 divided by 78 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 624 from 631 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 78

Moving on to step 5:
The number 78 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 1080.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 78

Moving on to step 6:
When dividing 727 by 78, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 10809.0
Subtracting 702 from 727 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
The number 78 fits into 250 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 10809.3
Deduct 234 from 250 and we're left 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.

Advancing to step 8:
160 divided by 78 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 10809.32
Subtract 156 from 160 to 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.

On to step 9:
40 divided by 78 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10809.32
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 78, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10809.3205
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.

Advancing to step 11:
100 divided by 78 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 10809.32051
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.

On to step 12:
78 goes into 220 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 10809.320512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
The number 78 fits into 640 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 10809.3205128
Deduct 624 from 640 and we're left 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.

Step 14:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10809.32051282
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.

The final result is 10809.32051282 with a remainder of 4e-09.
