We look at the division of 147443 by 39 
The aim is to understand the frequency of 39 in 147443.

Let's proceed to step 1:
1 divided by 39 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 39

Advancing to step 2:
If we divide 14 by 39, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 39

On to step 3:
If we divide 147 by 39, we get 3 and a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 117 from 147 and we're left with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 39

Step 4:
If we divide 304 by 39, we get 7 and a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 273 from 304 to get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 39

Moving on to step 5:
If we divide 314 by 39, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 378.0
If we take 312 away from 314, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 39

Going ahead to step 6:
39 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 3780.0
If we take 0 away from 23, 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.

Going ahead to step 7:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3780.5
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.

Moving on to step 8:
39 goes into 350 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 3780.58
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.

Moving on to step 9:
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: 3780.589
Subtracting 351 from 380 leaves us 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 10:
If we divide 290 by 39, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 3780.5897
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.

Going ahead to step 11:
39 goes into 170 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3780.58974
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 12:
140 divided by 39 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 3780.589743
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.

Advancing to step 13:
The number 39 fits into 230 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 3780.5897435
Deduct 195 from 230 and we're left 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.

Going ahead to step 14:
If we divide 350 by 39, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 3780.58974358
Deduct 312 from 350 and we're left 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.

The quotient of the division is 3780.58974358, and the remainder is 3.8e-08.
