We divide 202170 by 39
The aim is to understand the frequency of 39 in 202170.

Going ahead to step 1:
The number 39 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 39

Let's proceed to step 2:
The number 39 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 39

Step 3:
If we divide 202 by 39, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 195 from 202, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 39

Going ahead to step 4:
71 divided by 39 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 39 from 71 leaves us with 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 39

Going ahead to step 5:
When dividing 327 by 39, we get 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 518.0
Subtract 312 from 327 to get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 39

Step 6:
When dividing 150 by 39, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 5183.0
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 5183.8
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
When dividing 180 by 39, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 5183.84
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
If we divide 240 by 39, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 5183.846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 5183.8461
If we subtract 39 from 60, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
39 goes into 210 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5183.84615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
39 goes into 150 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 5183.846153
Subtracting 117 from 150 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
330 divided by 39 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 5183.8461538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 39 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 5183.84615384
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 5183.84615384 with a remaining 2.4e-08.
