We're dividing 39359603 by 781 
The aim is to understand the frequency of 781 in 39359603.

Let's proceed to step 1:
781 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 781

Moving on to step 2:
781 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 781

Moving on to step 3:
If we divide 393 by 781, we get 0 and a remainder of 393.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 393 after subtracting 0 from 393.
Append the next digit (5) from the dividend to 393 and continue with: 3935 / 781

Step 4:
781 goes into 3935 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 3905 from 3935 to get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 781

Let's proceed to step 5:
The number 781 fits into 309 0 times, leaving a remainder of 309.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 309 leaves us with 309.
Fetch the next digit (6) from the dividend, attach it to 309 and continue: 3096 / 781

Advancing to step 6:
If we divide 3096 by 781, we get 3 and a remainder of 753.
Use 3 as the next digit of our solution. 
Result so far: 503.0
If we take 2343 away from 3096, we end up with 753.
Grab the next digit (0) from the dividend, add it to 753, then carry on: 7530 / 781

On to step 7:
7530 divided by 781 is 9 with a remainder of 501.
Write down 9 as next digit of the result. 
Result so far: 5039.0
Subtract 7029 from 7530 to get 501.
Fetch the next digit (3) from the dividend, attach it to 501 and continue: 5013 / 781

Let's proceed to step 8:
781 can be fit into 5013 6 times, resulting in a remainder of 327.
Use 6 as the next digit of our solution. 
Result so far: 50396.0
Subtracting 4686 from 5013 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 9:
781 can be fit into 3270 4 times, resulting in a remainder of 146.
Record the quotient 4 as the next digit in the result. 
Result so far: 50396.4
If we subtract 3124 from 3270, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 10:
781 goes into 1460 1 times with a remainder of 679.
Use 1 as the next digit of our solution. 
Result so far: 50396.41
Subtracting 781 from 1460 leaves us with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Advancing to step 11:
If we divide 6790 by 781, we get 8 and a remainder of 542.
Write down 8 as next digit of the result. 
Result so far: 50396.418
Subtract 6248 from 6790 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 12:
5420 divided by 781 is 6 with a remainder of 734.
The number 6 becomes the next digit in our result. 
Result so far: 50396.4186
Deduct 4686 from 5420 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

On to step 13:
If we divide 7340 by 781, we get 9 and a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 50396.41869
The remainder is 311 after subtracting 7029 from 7340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 14:
The number 781 fits into 3110 3 times, leaving a remainder of 767.
Use 3 as the next digit of our solution. 
Result so far: 50396.418693
The remainder is 767 after subtracting 2343 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Let's proceed to step 15:
781 can be fit into 7670 9 times, resulting in a remainder of 641.
Write down 9 as next digit of the result. 
Result so far: 50396.4186939
Subtracting 7029 from 7670 leaves us with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Let's proceed to step 16:
6410 divided by 781 is 8 with a remainder of 162.
The next digit of our result is 8. 
Result so far: 50396.41869398
If we subtract 6248 from 6410, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final result is 50396.41869398 with a remainder of 1.62e-07.
