Let's divide 49883745 by 649
The aim is to understand the frequency of 649 in 49883745.

Step 1:
When dividing 4 by 649, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 649

On to step 2:
The number 649 fits into 49 0 times, leaving a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 649

Moving on to step 3:
If we divide 498 by 649, we get 0 and a remainder of 498.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 498 after subtracting 0 from 498.
Grab the next digit (8) from the dividend, add it to 498, then carry on: 4988 / 649

On to step 4:
4988 divided by 649 is 7 with a remainder of 445.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 445 after subtracting 4543 from 4988.
Grab the next digit (3) from the dividend, add it to 445, then carry on: 4453 / 649

Let's proceed to step 5:
649 goes into 4453 6 times with a remainder of 559.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 3894 from 4453 to get 559.
Fetch the next digit (7) from the dividend, attach it to 559 and continue: 5597 / 649

Let's proceed to step 6:
5597 divided by 649 is 8 with a remainder of 405.
Put 8 as the next digit of the answer. 
Result so far: 768.0
If we take 5192 away from 5597, we end up with 405.
Include the next digit (4) from the dividend after 405, then repeat: 4054 / 649

On to step 7:
649 can be fit into 4054 6 times, resulting in a remainder of 160.
The next digit of our result is 6. 
Result so far: 7686.0
The remainder is 160 after subtracting 3894 from 4054.
Append the next digit (5) from the dividend to 160 and continue with: 1605 / 649

Moving on to step 8:
The number 649 fits into 1605 2 times, leaving a remainder of 307.
Put 2 as the next digit of the answer. 
Result so far: 76862.0
If we subtract 1298 from 1605, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 9:
If we divide 3070 by 649, we get 4 and a remainder of 474.
The next digit of our result is 4. 
Result so far: 76862.4
Subtracting 2596 from 3070 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 10:
The number 649 fits into 4740 7 times, leaving a remainder of 197.
Record the quotient 7 as the next digit in the result. 
Result so far: 76862.47
Subtract 4543 from 4740 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 11:
The number 649 fits into 1970 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 76862.473
Deduct 1947 from 1970 and we're left with 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 12:
230 divided by 649 is 0 with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 76862.473
If we take 0 away from 230, we end up 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.

Advancing to step 13:
2300 divided by 649 is 3 with a remainder of 353.
Use 3 as the next digit of our solution. 
Result so far: 76862.47303
The remainder is 353 after subtracting 1947 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 14:
If we divide 3530 by 649, we get 5 and a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 76862.473035
If we subtract 3245 from 3530, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 15:
When dividing 2850 by 649, we get 4 with a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 76862.4730354
The remainder is 254 after subtracting 2596 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 16:
When dividing 2540 by 649, we get 3 with a remainder of 593.
Put 3 as the next digit of the answer. 
Result so far: 76862.47303543
If we subtract 1947 from 2540, we get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Our division results in 76862.47303543 with a remaining 5.93e-07.
