Let's divide 86696509 by 49
The aim is to understand the frequency of 49 in 86696509.

Let's proceed to step 1:
49 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 49

Moving on to step 2:
49 goes into 86 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 49 from 86 leaves us with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 49

Step 3:
If we divide 376 by 49, we get 7 and a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 343 from 376 to get 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 49

Going ahead to step 4:
339 divided by 49 is 6 with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
If we subtract 294 from 339, we get 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 49

Moving on to step 5:
49 goes into 456 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 1769.0
The remainder is 15 after subtracting 441 from 456.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 49

Advancing to step 6:
49 can be fit into 155 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 17693.0
The remainder is 8 after subtracting 147 from 155.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 49

On to step 7:
49 goes into 80 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 176931.0
If we subtract 49 from 80, we get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 49

Moving on to step 8:
49 goes into 319 6 times with a remainder of 25.
The next digit of our result is 6. 
Result so far: 1769316.0
If we take 294 away from 319, we end up 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.

Let's proceed to step 9:
49 goes into 250 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1769316.5
If we subtract 245 from 250, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
50 divided by 49 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1769316.51
Subtract 49 from 50 to 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 11:
49 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1769316.51
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 12:
If we divide 100 by 49, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1769316.5102
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
20 divided by 49 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1769316.5102
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
49 goes into 200 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 1769316.510204
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
If we divide 40 by 49, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1769316.510204
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
When dividing 400 by 49, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1769316.51020408
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 1769316.51020408 and a remainder of 8e-09.
