We look at the division of 469171 by 39 
The aim is to understand the frequency of 39 in 469171.

Going ahead to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 39

Moving on to step 2:
The number 39 fits into 46 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 46 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 39

On to step 3:
The number 39 fits into 79 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 78 from 79 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 39

Advancing to step 4:
39 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 11, we get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 39

On to step 5:
117 divided by 39 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1203.0
The remainder is 0 after subtracting 117 from 117.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 39

On to step 6:
The number 39 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 12030.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 39, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12030.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
39 goes into 100 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 12030.02
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
39 goes into 220 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12030.025
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
39 goes into 250 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 12030.0256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 39, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 12030.02564
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
When dividing 40 by 39, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 12030.025641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
If we divide 10 by 39, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12030.025641
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
39 goes into 100 2 times with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 12030.02564102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 12030.02564102 with a remainder of 2.2e-08.
