We divide 18537968 by 78
The aim is to understand the frequency of 78 in 18537968.

Moving on to step 1:
78 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 78

Step 2:
When dividing 18 by 78, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 78

Step 3:
If we divide 185 by 78, we get 2 and a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 156 from 185 and we're left with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 78

Step 4:
If we divide 293 by 78, we get 3 and a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 234 from 293 leaves us with 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 78

Moving on to step 5:
78 goes into 597 7 times with a remainder of 51.
The next digit of our result is 7. 
Result so far: 237.0
The remainder is 51 after subtracting 546 from 597.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 78

Advancing to step 6:
The number 78 fits into 519 6 times, leaving a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 2376.0
The remainder is 51 after subtracting 468 from 519.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 78

Step 7:
When dividing 516 by 78, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 23766.0
Subtracting 468 from 516 leaves us with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 78

Going ahead to step 8:
When dividing 488 by 78, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 237666.0
Subtract 468 from 488 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 78 fits into 200 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 237666.2
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 237666.25
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 237666.256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 237666.2564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 78 fits into 80 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 237666.25641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
If we divide 20 by 78, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 237666.25641
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
78 goes into 200 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 237666.2564102
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 16:
When dividing 440 by 78, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 237666.25641025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 237666.25641025, and the remainder is 5e-08.
