Let's divide 420615 by 39
The aim is to understand the frequency of 39 in 420615.

Going ahead to step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 39

Moving on to step 2:
When dividing 42 by 39, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 3 after subtracting 39 from 42.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 39

Let's proceed to step 3:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 30 to get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 39

Going ahead to step 4:
The number 39 fits into 306 7 times, leaving a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Deduct 273 from 306 and we're left with 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 39

On to step 5:
If we divide 331 by 39, we get 8 and a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 1078.0
The remainder is 19 after subtracting 312 from 331.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 39

Let's proceed to step 6:
39 goes into 195 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10785.0
Subtracting 195 from 195 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 39 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10785.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
39 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10785.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 10785.0, and the remainder is 0.0.
