Let's divide 36129983 by 649
The aim is to understand the frequency of 649 in 36129983.

Advancing to step 1:
649 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 649

Going ahead to step 2:
When dividing 36 by 649, we get 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 649

On to step 3:
649 can be fit into 361 0 times, resulting in a remainder of 361.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 361 to get 361.
Include the next digit (2) from the dividend after 361, then repeat: 3612 / 649

Step 4:
3612 divided by 649 is 5 with a remainder of 367.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 367 after subtracting 3245 from 3612.
Grab the next digit (9) from the dividend, add it to 367, then carry on: 3679 / 649

Step 5:
649 can be fit into 3679 5 times, resulting in a remainder of 434.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
The remainder is 434 after subtracting 3245 from 3679.
Fetch the next digit (9) from the dividend, attach it to 434 and continue: 4349 / 649

Step 6:
If we divide 4349 by 649, we get 6 and a remainder of 455.
Write down 6 as next digit of the result. 
Result so far: 556.0
Deduct 3894 from 4349 and we're left with 455.
Grab the next digit (8) from the dividend, add it to 455, then carry on: 4558 / 649

Advancing to step 7:
When dividing 4558 by 649, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 5567.0
If we take 4543 away from 4558, we end up with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 649

On to step 8:
649 can be fit into 153 0 times, resulting in a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 55670.0
Subtract 0 from 153 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 9:
If we divide 1530 by 649, we get 2 and a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 55670.2
Subtract 1298 from 1530 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 10:
649 goes into 2320 3 times with a remainder of 373.
Use 3 as the next digit of our solution. 
Result so far: 55670.23
If we subtract 1947 from 2320, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 11:
If we divide 3730 by 649, we get 5 and a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 55670.235
Subtracting 3245 from 3730 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 12:
4850 divided by 649 is 7 with a remainder of 307.
Use 7 as the next digit of our solution. 
Result so far: 55670.2357
Deduct 4543 from 4850 and we're left with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 13:
If we divide 3070 by 649, we get 4 and a remainder of 474.
Use 4 as the next digit of our solution. 
Result so far: 55670.23574
If we subtract 2596 from 3070, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 14:
If we divide 4740 by 649, we get 7 and a remainder of 197.
The next digit of our result is 7. 
Result so far: 55670.235747
Subtracting 4543 from 4740 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 15:
649 can be fit into 1970 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 55670.2357473
Subtract 1947 from 1970 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 16:
When dividing 230 by 649, we get 0 with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 55670.2357473
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Our division results in 55670.2357473 with a remaining 2.3e-07.
