84951654 ÷ 39 
The aim is to understand the frequency of 39 in 84951654.

Let's proceed to step 1:
39 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 39

On to step 2:
If we divide 84 by 39, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 78 from 84 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 39

Going ahead to step 3:
The number 39 fits into 69 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 30 after subtracting 39 from 69.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 39

Advancing to step 4:
The number 39 fits into 305 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 217.0
If we take 273 away from 305, we end up with 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 39

Let's proceed to step 5:
The number 39 fits into 321 8 times, leaving a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 2178.0
Deduct 312 from 321 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 39

On to step 6:
39 goes into 96 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 21782.0
Subtract 78 from 96 to get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 39

Advancing to step 7:
The number 39 fits into 185 4 times, leaving a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 217824.0
Subtract 156 from 185 to get 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 39

Advancing to step 8:
39 goes into 294 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 2178247.0
Deduct 273 from 294 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2178247.5
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
39 goes into 150 3 times with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 2178247.53
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 2178247.538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
39 can be fit into 180 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 2178247.5384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 39, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 2178247.53846
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 39 fits into 60 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 2178247.538461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 15:
39 can be fit into 210 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2178247.5384615
Subtracting 195 from 210 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 16:
If we divide 150 by 39, we get 3 and a remainder of 33.
The next digit of our result is 3. 
Result so far: 2178247.53846153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 2178247.53846153 and a remainder of 3.3e-08.
