We're dividing 50980 by 57 
The aim is to understand the frequency of 57 in 50980.

On to step 1:
When dividing 5 by 57, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 57

Moving on to step 2:
57 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 57

Step 3:
The number 57 fits into 509 8 times, leaving a remainder of 53.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 456 away from 509, we end up with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 57

Step 4:
57 can be fit into 538 9 times, resulting in a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Deduct 513 from 538 and we're left with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 57

Advancing to step 5:
57 can be fit into 250 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 894.0
Subtract 228 from 250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 6:
The number 57 fits into 220 3 times, leaving a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 894.3
The remainder is 49 after subtracting 171 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
The number 57 fits into 490 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 894.38
Deduct 456 from 490 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
The number 57 fits into 340 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 894.385
If we take 285 away from 340, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
When dividing 550 by 57, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 894.3859
Deduct 513 from 550 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
The number 57 fits into 370 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 894.38596
Subtract 342 from 370 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
280 divided by 57 is 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 894.385964
Deduct 228 from 280 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
The number 57 fits into 520 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 894.3859649
If we subtract 513 from 520, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
When dividing 70 by 57, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 894.38596491
Deduct 57 from 70 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 894.38596491 and a remainder of 1.3e-08.
