We divide 81814934 by 39
The aim is to understand the frequency of 39 in 81814934.

On to step 1:
39 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 39

Moving on to step 2:
If we divide 81 by 39, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 3 after subtracting 78 from 81.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 39

Step 3:
The number 39 fits into 38 0 times, leaving a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 39

Step 4:
The number 39 fits into 381 9 times, leaving a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
The remainder is 30 after subtracting 351 from 381.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 39

Step 5:
304 divided by 39 is 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 2097.0
If we subtract 273 from 304, we get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 39

Advancing to step 6:
39 can be fit into 319 8 times, resulting in a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 20978.0
Subtracting 312 from 319 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 39

Advancing to step 7:
If we divide 73 by 39, we get 1 and a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 209781.0
The remainder is 34 after subtracting 39 from 73.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 39

Step 8:
When dividing 344 by 39, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 2097818.0
Deduct 312 from 344 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
When dividing 320 by 39, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2097818.8
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 39, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2097818.82
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 39 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2097818.82
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
39 goes into 200 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2097818.8205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
If we divide 50 by 39, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 2097818.82051
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
If we divide 110 by 39, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 2097818.820512
The remainder is 32 after subtracting 78 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
320 divided by 39 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2097818.8205128
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 16:
80 divided by 39 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2097818.82051282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 2097818.82051282, with a leftover of 2e-09.
