We divide 307436 by 78
The aim is to understand the frequency of 78 in 307436.

Moving on to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 78

Moving on to step 2:
If we divide 30 by 78, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 78

Step 3:
If we divide 307 by 78, we get 3 and a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 234 from 307 leaves us with 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 78

Moving on to step 4:
78 can be fit into 734 9 times, resulting in a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 702 away from 734, we end up with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 78

On to step 5:
When dividing 323 by 78, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 394.0
The remainder is 11 after subtracting 312 from 323.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 78

Let's proceed to step 6:
If we divide 116 by 78, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 3941.0
If we take 78 away from 116, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
When dividing 380 by 78, we get 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 3941.4
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
78 goes into 680 8 times with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 3941.48
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
78 goes into 560 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 3941.487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 3941.4871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
620 divided by 78 is 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 3941.48717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
If we divide 740 by 78, we get 9 and a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 3941.487179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
The next digit of our result is 4. 
Result so far: 3941.4871794
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
680 divided by 78 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 3941.48717948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 3941.48717948 with a remainder of 5.6e-08.
