We look at the division of 942803 by 39 
The aim is to understand the frequency of 39 in 942803.

On to step 1:
39 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 39

Advancing to step 2:
94 divided by 39 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 78 from 94 to get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 39

Step 3:
162 divided by 39 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 156 from 162, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 39

Step 4:
If we divide 68 by 39, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 241.0
Deduct 39 from 68 and we're left with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 39

Advancing to step 5:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2417.0
If we take 273 away from 290, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 39

Advancing to step 6:
39 can be fit into 173 4 times, resulting in a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 24174.0
Subtracting 156 from 173 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 39, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 24174.4
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
39 goes into 140 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 24174.43
Subtracting 117 from 140 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 9:
39 goes into 230 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 24174.435
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
39 can be fit into 350 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 24174.4358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
When dividing 380 by 39, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 24174.43589
Deduct 351 from 380 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
When dividing 290 by 39, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 24174.435897
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 24174.4358974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
39 goes into 140 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 24174.43589743
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 24174.43589743 with a balance of 2.3e-08.
