404914 ÷ 57 
The aim is to understand the frequency of 57 in 404914.

Step 1:
57 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 57

On to step 2:
40 divided by 57 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 57

Going ahead to step 3:
57 can be fit into 404 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 399 from 404 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 57

Step 4:
59 divided by 57 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtracting 57 from 59 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 57

On to step 5:
57 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 710.0
If we subtract 0 from 21, we get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 57

Going ahead to step 6:
214 divided by 57 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 7103.0
Subtracting 171 from 214 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
57 goes into 430 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7103.7
If we take 399 away from 430, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
When dividing 310 by 57, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7103.75
If we subtract 285 from 310, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
When dividing 250 by 57, we get 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 7103.754
If we take 228 away from 250, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
When dividing 220 by 57, we get 3 with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 7103.7543
If we subtract 171 from 220, we get 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 11:
490 divided by 57 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 7103.75438
Subtracting 456 from 490 leaves us 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.

On to step 12:
57 goes into 340 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 7103.754385
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.

Advancing to step 13:
57 can be fit into 550 9 times, resulting in a remainder of 37.
The next digit of our result is 9. 
Result so far: 7103.7543859
The remainder is 37 after subtracting 513 from 550.
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 14:
57 can be fit into 370 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 7103.75438596
Deduct 342 from 370 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 7103.75438596, with a leftover of 2.8e-08.
