We look at the division of 72684601 by 39 
The aim is to understand the frequency of 39 in 72684601.

Step 1:
39 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 39

Going ahead to step 2:
39 goes into 72 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 39 from 72 to get 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 39

On to step 3:
When dividing 336 by 39, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 24 after subtracting 312 from 336.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 39

Moving on to step 4:
248 divided by 39 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
If we take 234 away from 248, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 39

On to step 5:
When dividing 144 by 39, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 1863.0
If we take 117 away from 144, we end up with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 39

Going ahead to step 6:
The number 39 fits into 276 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 18637.0
The remainder is 3 after subtracting 273 from 276.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 39

On to step 7:
30 divided by 39 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 186370.0
If we subtract 0 from 30, we get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 39

On to step 8:
39 goes into 301 7 times with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 1863707.0
The remainder is 28 after subtracting 273 from 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
If we divide 280 by 39, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1863707.7
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
The number 39 fits into 70 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 1863707.71
Deduct 39 from 70 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
If we divide 310 by 39, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 1863707.717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 1863707.7179
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1863707.71794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
340 divided by 39 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1863707.717948
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 15:
The number 39 fits into 280 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 1863707.7179487
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 16:
If we divide 70 by 39, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1863707.71794871
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 1863707.71794871 with a remaining 3.1e-08.
