We look at the division of 461920 by 57 
The aim is to understand the frequency of 57 in 461920.

Going ahead to step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 57

Step 2:
46 divided by 57 is 0 with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 57

Advancing to step 3:
When dividing 461 by 57, we get 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 456 from 461 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 57

Advancing to step 4:
When dividing 59 by 57, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we take 57 away from 59, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 57

Let's proceed to step 5:
57 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 810.0
If we take 0 away from 22, we end up with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 57

Going ahead to step 6:
When dividing 220 by 57, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 8103.0
Deduct 171 from 220 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
490 divided by 57 is 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 8103.8
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
If we divide 340 by 57, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 8103.85
Subtract 285 from 340 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
When dividing 550 by 57, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 8103.859
If we take 513 away from 550, we end up 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.

Moving on to step 10:
57 goes into 370 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 8103.8596
The remainder is 28 after subtracting 342 from 370.
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: 8103.85964
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:
When dividing 520 by 57, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 8103.859649
Deduct 513 from 520 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
57 can be fit into 70 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 8103.8596491
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
57 goes into 130 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 8103.85964912
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 8103.85964912 with a remaining 1.6e-08.
