We divide 350542 by 78
The aim is to understand the frequency of 78 in 350542.

Moving on to step 1:
78 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 78

Let's proceed to step 2:
78 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 78

On to step 3:
When dividing 350 by 78, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 312 from 350, we get 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 78

Moving on to step 4:
78 can be fit into 385 4 times, resulting in a remainder of 73.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 312 from 385 leaves us with 73.
Bring next digit (4) of the dividend behind the 73 and repeat the process: 734 / 78

Advancing to step 5:
If we divide 734 by 78, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 449.0
If we take 702 away from 734, we end up with 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 78

On to step 6:
78 can be fit into 322 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 4494.0
If we take 312 away from 322, 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.

On to step 7:
100 divided by 78 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 4494.1
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 8:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 4494.12
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.

Let's proceed to step 9:
640 divided by 78 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 4494.128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 4494.1282
Deduct 156 from 160 and we're left 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.

Step 11:
40 divided by 78 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4494.1282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
78 goes into 400 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4494.128205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
If we divide 100 by 78, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 4494.1282051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 4494.12820512
Subtracting 156 from 220 leaves us 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.

After the division, we end up with 4494.12820512 and a remainder of 6.4e-08.
