We look at the division of 50370645 by 983 
The aim is to understand the frequency of 983 in 50370645.

Let's proceed to step 1:
When dividing 5 by 983, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 983

Let's proceed to step 2:
If we divide 50 by 983, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 983

Step 3:
983 goes into 503 0 times with a remainder of 503.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 503, we end up with 503.
Bring next digit (7) of the dividend behind the 503 and repeat the process: 5037 / 983

Let's proceed to step 4:
5037 divided by 983 is 5 with a remainder of 122.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 122 after subtracting 4915 from 5037.
Include the next digit (0) from the dividend after 122, then repeat: 1220 / 983

On to step 5:
983 can be fit into 1220 1 times, resulting in a remainder of 237.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 983 from 1220 leaves us with 237.
Bring next digit (6) of the dividend behind the 237 and repeat the process: 2376 / 983

Advancing to step 6:
The number 983 fits into 2376 2 times, leaving a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtracting 1966 from 2376 leaves us with 410.
Append the next digit (4) from the dividend to 410 and continue with: 4104 / 983

On to step 7:
When dividing 4104 by 983, we get 4 with a remainder of 172.
The next digit of our result is 4. 
Result so far: 5124.0
Deduct 3932 from 4104 and we're left with 172.
Fetch the next digit (5) from the dividend, attach it to 172 and continue: 1725 / 983

Step 8:
983 can be fit into 1725 1 times, resulting in a remainder of 742.
Write down 1 as next digit of the result. 
Result so far: 51241.0
Subtract 983 from 1725 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Moving on to step 9:
When dividing 7420 by 983, we get 7 with a remainder of 539.
Record the quotient 7 as the next digit in the result. 
Result so far: 51241.7
The remainder is 539 after subtracting 6881 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Moving on to step 10:
983 goes into 5390 5 times with a remainder of 475.
The next digit of our result is 5. 
Result so far: 51241.75
Deduct 4915 from 5390 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 11:
If we divide 4750 by 983, we get 4 and a remainder of 818.
Record the quotient 4 as the next digit in the result. 
Result so far: 51241.754
Deduct 3932 from 4750 and we're left with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Going ahead to step 12:
983 goes into 8180 8 times with a remainder of 316.
The next digit of our result is 8. 
Result so far: 51241.7548
The remainder is 316 after subtracting 7864 from 8180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 13:
3160 divided by 983 is 3 with a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 51241.75483
If we take 2949 away from 3160, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 14:
2110 divided by 983 is 2 with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 51241.754832
Subtract 1966 from 2110 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 15:
If we divide 1440 by 983, we get 1 and a remainder of 457.
The next digit of our result is 1. 
Result so far: 51241.7548321
If we subtract 983 from 1440, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 16:
If we divide 4570 by 983, we get 4 and a remainder of 638.
Use 4 as the next digit of our solution. 
Result so far: 51241.75483214
If we take 3932 away from 4570, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

In conclusion, the division gives 51241.75483214 with a balance of 6.38e-07.
