We're dividing 51505983 by 724 
The aim is to understand the frequency of 724 in 51505983.

Let's proceed to step 1:
724 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 724

Moving on to step 2:
724 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 724

Going ahead to step 3:
724 goes into 515 0 times with a remainder of 515.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 515 and we're left with 515.
Bring next digit (0) of the dividend behind the 515 and repeat the process: 5150 / 724

On to step 4:
The number 724 fits into 5150 7 times, leaving a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 5068 from 5150 to get 82.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 724

On to step 5:
The number 724 fits into 825 1 times, leaving a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Deduct 724 from 825 and we're left with 101.
Fetch the next digit (9) from the dividend, attach it to 101 and continue: 1019 / 724

Let's proceed to step 6:
724 can be fit into 1019 1 times, resulting in a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 711.0
If we take 724 away from 1019, we end up with 295.
Take the next digit (8) from the dividend and append it to 295, then repeat: 2958 / 724

Step 7:
If we divide 2958 by 724, we get 4 and a remainder of 62.
The next digit of our result is 4. 
Result so far: 7114.0
Subtracting 2896 from 2958 leaves us with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 724

Moving on to step 8:
623 divided by 724 is 0 with a remainder of 623.
Record the quotient 0 as the next digit in the result. 
Result so far: 71140.0
Subtracting 0 from 623 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Step 9:
6230 divided by 724 is 8 with a remainder of 438.
Write down 8 as next digit of the result. 
Result so far: 71140.8
If we take 5792 away from 6230, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 10:
724 goes into 4380 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 71140.86
Subtracting 4344 from 4380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
724 can be fit into 360 0 times, resulting in a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 71140.86
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
The number 724 fits into 3600 4 times, leaving a remainder of 704.
Use 4 as the next digit of our solution. 
Result so far: 71140.8604
If we take 2896 away from 3600, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Moving on to step 13:
When dividing 7040 by 724, we get 9 with a remainder of 524.
Put 9 as the next digit of the answer. 
Result so far: 71140.86049
If we take 6516 away from 7040, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 14:
724 can be fit into 5240 7 times, resulting in a remainder of 172.
The next digit of our result is 7. 
Result so far: 71140.860497
The remainder is 172 after subtracting 5068 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 15:
1720 divided by 724 is 2 with a remainder of 272.
Write down 2 as next digit of the result. 
Result so far: 71140.8604972
Deduct 1448 from 1720 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 16:
The number 724 fits into 2720 3 times, leaving a remainder of 548.
The number 3 becomes the next digit in our result. 
Result so far: 71140.86049723
If we take 2172 away from 2720, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

In conclusion, the division gives 71140.86049723 with a balance of 5.48e-07.
