157373 ÷ 78 
The aim is to understand the frequency of 78 in 157373.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 78

Step 2:
When dividing 15 by 78, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 78

Going ahead to step 3:
When dividing 157 by 78, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 156 from 157 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 78

Going ahead to step 4:
13 divided by 78 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 13, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 78

Going ahead to step 5:
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: 201.0
If we take 78 away from 137, we end up with 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 78

Advancing to step 6:
78 can be fit into 593 7 times, resulting in a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 2017.0
Subtract 546 from 593 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
470 divided by 78 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 2017.6
The remainder is 2 after subtracting 468 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 78, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2017.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 78 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 2017.602
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.

Going ahead to step 10:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2017.6025
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.

On 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: 2017.60256
Deduct 468 from 500 and we're left 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.

Step 12:
The number 78 fits into 320 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 2017.602564
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
When dividing 80 by 78, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 2017.6025641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
When dividing 20 by 78, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2017.6025641
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 2017.6025641 with a remainder of 2e-08.
