Let's divide 403701 by 78
The aim is to understand the frequency of 78 in 403701.

On to step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 78

Let's proceed to step 2:
78 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 78

Moving on to step 3:
The number 78 fits into 403 5 times, leaving a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 390 from 403 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 78

Advancing to step 4:
If we divide 137 by 78, we get 1 and a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 78 from 137, we get 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 78

Let's proceed to step 5:
78 can be fit into 590 7 times, resulting in a remainder of 44.
The next digit of our result is 7. 
Result so far: 517.0
If we subtract 546 from 590, we get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 78

Let's proceed to step 6:
78 goes into 441 5 times with a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 5175.0
If we take 390 away from 441, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
78 goes into 510 6 times with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 5175.6
The remainder is 42 after subtracting 468 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
420 divided by 78 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5175.65
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
78 goes into 300 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 5175.653
If we subtract 234 from 300, we get 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 10:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 5175.6538
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.

Going ahead to step 11:
78 goes into 360 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 5175.65384
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.

Advancing to step 12:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 5175.653846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 5175.6538461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
78 goes into 420 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5175.65384615
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.

After the division, we end up with 5175.65384615 and a remainder of 3e-08.
