We divide 386891 by 78
The aim is to understand the frequency of 78 in 386891.

Let's proceed to step 1:
The number 78 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 78

Advancing to step 2:
78 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 78

Let's proceed to step 3:
78 goes into 386 4 times with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 312 away from 386, we end up with 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 78

Let's proceed to step 4:
If we divide 748 by 78, we get 9 and a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 702 from 748 and we're left with 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 78

On to step 5:
The number 78 fits into 469 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 496.0
Deduct 468 from 469 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 78

On to step 6:
78 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 4960.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
110 divided by 78 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 4960.1
If we take 78 away from 110, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
78 goes into 320 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4960.14
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 78, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 4960.141
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 78, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4960.141
If we subtract 0 from 20, we 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 11:
When dividing 200 by 78, we get 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 4960.14102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4960.141025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 78, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 4960.1410256
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
78 can be fit into 320 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4960.14102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 4960.14102564, and the remainder is 8e-09.
