103983 divided by 51 
The aim is to understand the frequency of 51 in 103983.

Let's proceed to step 1:
1 divided by 51 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 51

Moving on to step 2:
If we divide 10 by 51, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 51

Advancing to step 3:
When dividing 103 by 51, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 102 from 103.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 51

Step 4:
When dividing 19 by 51, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 19, we get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 51

On to step 5:
When dividing 198 by 51, we get 3 with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
Subtracting 153 from 198 leaves us with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 51

Going ahead to step 6:
When dividing 453 by 51, we get 8 with a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 2038.0
Deduct 408 from 453 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
When dividing 450 by 51, we get 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 2038.8
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2038.88
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 2038.88 with a balance of 0.012.
