Let's divide 39878439 by 763
The aim is to understand the frequency of 763 in 39878439.

Let's proceed to step 1:
The number 763 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 763

Going ahead to step 2:
763 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 763

Step 3:
When dividing 398 by 763, we get 0 with a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 398 leaves us with 398.
Append the next digit (7) from the dividend to 398 and continue with: 3987 / 763

On to step 4:
When dividing 3987 by 763, we get 5 with a remainder of 172.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 172 after subtracting 3815 from 3987.
Bring next digit (8) of the dividend behind the 172 and repeat the process: 1728 / 763

Step 5:
763 goes into 1728 2 times with a remainder of 202.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 1526 from 1728 leaves us with 202.
Include the next digit (4) from the dividend after 202, then repeat: 2024 / 763

Moving on to step 6:
The number 763 fits into 2024 2 times, leaving a remainder of 498.
The next digit of our result is 2. 
Result so far: 522.0
Deduct 1526 from 2024 and we're left with 498.
Take the next digit (3) from the dividend and append it to 498, then repeat: 4983 / 763

Let's proceed to step 7:
4983 divided by 763 is 6 with a remainder of 405.
The number 6 becomes the next digit in our result. 
Result so far: 5226.0
Subtract 4578 from 4983 to get 405.
Append the next digit (9) from the dividend to 405 and continue with: 4059 / 763

Going ahead to step 8:
4059 divided by 763 is 5 with a remainder of 244.
The next digit of our result is 5. 
Result so far: 52265.0
The remainder is 244 after subtracting 3815 from 4059.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 9:
763 can be fit into 2440 3 times, resulting in a remainder of 151.
Record the quotient 3 as the next digit in the result. 
Result so far: 52265.3
Deduct 2289 from 2440 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 10:
1510 divided by 763 is 1 with a remainder of 747.
Write down 1 as next digit of the result. 
Result so far: 52265.31
If we subtract 763 from 1510, we get 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Let's proceed to step 11:
763 goes into 7470 9 times with a remainder of 603.
Use 9 as the next digit of our solution. 
Result so far: 52265.319
Subtracting 6867 from 7470 leaves us with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Advancing to step 12:
If we divide 6030 by 763, we get 7 and a remainder of 689.
Record the quotient 7 as the next digit in the result. 
Result so far: 52265.3197
Subtracting 5341 from 6030 leaves us with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Let's proceed to step 13:
763 can be fit into 6890 9 times, resulting in a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 52265.31979
If we take 6867 away from 6890, we end up 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.

Moving on to step 14:
When dividing 230 by 763, we get 0 with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 52265.31979
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 15:
The number 763 fits into 2300 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 52265.3197903
Subtracting 2289 from 2300 leaves us 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 16:
If we divide 110 by 763, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 52265.3197903
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Our division results in 52265.3197903 with a remaining 1.1e-07.
