30835221 divided by 78 
The aim is to understand the frequency of 78 in 30835221.

On to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 78

Let's proceed to step 2:
78 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 78

Going ahead to step 3:
78 goes into 308 3 times with a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 234 from 308, we get 74.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 78

On to step 4:
The number 78 fits into 743 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 702 from 743 to get 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 78

Step 5:
78 can be fit into 415 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 395.0
If we subtract 390 from 415, we get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 78

Advancing to step 6:
78 goes into 252 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 3953.0
Subtract 234 from 252 to get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 78

Advancing to step 7:
When dividing 182 by 78, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 39532.0
Subtract 156 from 182 to get 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 78

On to step 8:
If we divide 261 by 78, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 395323.0
The remainder is 27 after subtracting 234 from 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
The number 78 fits into 270 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 395323.3
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
When dividing 360 by 78, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 395323.34
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
480 divided by 78 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 395323.346
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
If we divide 120 by 78, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 395323.3461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 395323.34615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 395323.346153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 15:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 395323.3461538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 16:
The number 78 fits into 360 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 395323.34615384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 395323.34615384, and the remainder is 4.8e-08.
