We look at the division of 78332964 by 103 
The aim is to understand the frequency of 103 in 78332964.

On to step 1:
If we divide 7 by 103, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 103

Advancing to step 2:
103 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 103

Step 3:
103 can be fit into 783 7 times, resulting in a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 721 from 783 to get 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 103

On to step 4:
When dividing 623 by 103, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 618 from 623 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 103

Let's proceed to step 5:
103 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 760.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 103

Step 6:
103 goes into 529 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 7605.0
Deduct 515 from 529 and we're left with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 103

Moving on to step 7:
The number 103 fits into 146 1 times, leaving a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 76051.0
If we take 103 away from 146, we end up with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 103

Moving on to step 8:
When dividing 434 by 103, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 760514.0
The remainder is 22 after subtracting 412 from 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
103 can be fit into 220 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 760514.2
Subtract 206 from 220 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
140 divided by 103 is 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 760514.21
Subtracting 103 from 140 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
When dividing 370 by 103, we get 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 760514.213
Subtract 309 from 370 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 12:
103 goes into 610 5 times with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 760514.2135
Subtracting 515 from 610 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 13:
The number 103 fits into 950 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 760514.21359
Subtracting 927 from 950 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
230 divided by 103 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 760514.213592
Deduct 206 from 230 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 15:
240 divided by 103 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 760514.2135922
If we subtract 206 from 240, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 760514.2135922 and a remainder of 3.4e-07.
