We look at the division of 545276 by 39 
The aim is to understand the frequency of 39 in 545276.

Step 1:
39 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 39

Moving on to step 2:
If we divide 54 by 39, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 39 from 54 to get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 39

Advancing to step 3:
If we divide 155 by 39, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 38 after subtracting 117 from 155.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 39

Step 4:
39 can be fit into 382 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Deduct 351 from 382 and we're left with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 39

Going ahead to step 5:
When dividing 317 by 39, we get 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 1398.0
If we subtract 312 from 317, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 39

Moving on to step 6:
56 divided by 39 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 13981.0
Subtract 39 from 56 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 13981.4
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.

Let's proceed to step 8:
If we divide 140 by 39, we get 3 and a remainder of 23.
The next digit of our result is 3. 
Result so far: 13981.43
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:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 13981.435
Subtract 195 from 230 to 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.

Let's proceed to step 10:
39 goes into 350 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 13981.4358
Subtracting 312 from 350 leaves us with 38.
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:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 13981.43589
If we subtract 351 from 380, we get 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 12:
If we divide 290 by 39, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 13981.435897
If we subtract 273 from 290, we get 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:
170 divided by 39 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 13981.4358974
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.

Let's proceed to step 14:
When dividing 140 by 39, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 13981.43589743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 13981.43589743, with a leftover of 2.3e-08.
