We divide 428635 by 39
The aim is to understand the frequency of 39 in 428635.

Let's proceed to step 1:
39 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 39

Advancing to step 2:
The number 39 fits into 42 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 39 from 42 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 39

Step 3:
38 divided by 39 is 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 39

Step 4:
39 can be fit into 386 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 351 from 386, we get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 39

Let's proceed to step 5:
39 goes into 353 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1099.0
The remainder is 2 after subtracting 351 from 353.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 39

On to step 6:
25 divided by 39 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 10990.0
If we subtract 0 from 25, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
When dividing 250 by 39, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 10990.6
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.

On to step 8:
If we divide 160 by 39, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 10990.64
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.

On to step 9:
39 can be fit into 40 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 10990.641
If we subtract 39 from 40, 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.

Advancing to step 10:
When dividing 10 by 39, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10990.641
If we subtract 0 from 10, we 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.

Let's proceed to step 11:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 10990.64102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
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: 10990.641025
If we subtract 195 from 220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
250 divided by 39 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 10990.6410256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 10990.64102564
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 10990.64102564, and the remainder is 4e-09.
