We look at the division of 141788 by 39 
The aim is to understand the frequency of 39 in 141788.

Moving on to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 39

Advancing to step 2:
If we divide 14 by 39, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 39

Moving on to step 3:
When dividing 141 by 39, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 24 after subtracting 117 from 141.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 39

Moving on to step 4:
The number 39 fits into 247 6 times, leaving a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 234 from 247 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 39

On to step 5:
39 goes into 138 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 363.0
Subtracting 117 from 138 leaves us with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 39

Going ahead to step 6:
If we divide 218 by 39, we get 5 and a remainder of 23.
The next digit of our result is 5. 
Result so far: 3635.0
Subtract 195 from 218 to 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.

Going ahead to step 7:
When dividing 230 by 39, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3635.5
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.

Going ahead to step 8:
39 goes into 350 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 3635.58
If we subtract 312 from 350, we 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.

Going ahead to step 9:
39 goes into 380 9 times with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 3635.589
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.

Moving on to step 10:
When dividing 290 by 39, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 3635.5897
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.

Advancing to step 11:
If we divide 170 by 39, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3635.58974
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.

Step 12:
39 goes into 140 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3635.589743
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.

On 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: 3635.5897435
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
When dividing 350 by 39, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 3635.58974358
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.

Our division results in 3635.58974358 with a remaining 3.8e-08.
