Let's divide 28994 by 39
The aim is to understand the frequency of 39 in 28994.

Advancing to step 1:
The number 39 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 39

Advancing to step 2:
39 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 39

Step 3:
289 divided by 39 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 273 away from 289, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 39

Step 4:
If we divide 169 by 39, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtract 156 from 169 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 39

Let's proceed to step 5:
If we divide 134 by 39, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 743.0
Subtracting 117 from 134 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.

Moving on to step 6:
39 goes into 170 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 743.4
Deduct 156 from 170 and we're left 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.

Moving on to step 7:
140 divided by 39 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 743.43
If we take 117 away from 140, we end up 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.

Moving on to step 8:
If we divide 230 by 39, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 743.435
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
39 goes into 350 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 743.4358
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 743.43589
If we take 351 away from 380, we end up 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.

Moving on to step 11:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 743.435897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
If we divide 170 by 39, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 743.4358974
If we subtract 156 from 170, we 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.

Going ahead to step 13:
If we divide 140 by 39, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 743.43589743
Deduct 117 from 140 and we're left 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.

The quotient of the division is 743.43589743, and the remainder is 2.3e-08.
