We divide 639859 by 39
The aim is to understand the frequency of 39 in 639859.

Let's proceed to step 1:
6 divided by 39 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 39

Let's proceed to step 2:
When dividing 63 by 39, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 39 from 63 and we're left with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 39

Moving on to step 3:
If we divide 249 by 39, we get 6 and a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 234 from 249 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 39

On to step 4:
39 can be fit into 158 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we subtract 156 from 158, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 39

Moving on to step 5:
The number 39 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 1640.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 39

On to step 6:
39 goes into 259 6 times with a remainder of 25.
The next digit of our result is 6. 
Result so far: 16406.0
Subtracting 234 from 259 leaves us 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.

Step 7:
39 goes into 250 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 16406.6
The remainder is 16 after subtracting 234 from 250.
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 8:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 16406.64
Subtracting 156 from 160 leaves us 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.

On to step 9:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 16406.641
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.

Step 10:
If we divide 10 by 39, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 16406.641
Deduct 0 from 10 and we're left 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.

Advancing to step 11:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 16406.64102
If we subtract 78 from 100, we get 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:
The number 39 fits into 220 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 16406.641025
Subtract 195 from 220 to 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.

On to step 13:
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: 16406.6410256
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.

Going ahead 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: 16406.64102564
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 final outcome is 16406.64102564, with a leftover of 4e-09.
