392836 divided by 57 
The aim is to understand the frequency of 57 in 392836.

Going ahead to step 1:
3 divided by 57 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 57

Going ahead to step 2:
The number 57 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 57

Let's proceed to step 3:
When dividing 392 by 57, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 342 from 392 leaves us with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 57

Step 4:
The number 57 fits into 508 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtract 456 from 508 to get 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 57

On to step 5:
When dividing 523 by 57, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 689.0
If we take 513 away from 523, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 57

Let's proceed to step 6:
The number 57 fits into 106 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 6891.0
If we subtract 57 from 106, 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.

On to step 7:
If we divide 490 by 57, we get 8 and a remainder of 34.
The next digit of our result is 8. 
Result so far: 6891.8
Subtract 456 from 490 to 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:
57 can be fit into 340 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 6891.85
Subtracting 285 from 340 leaves us 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.

Moving on to step 9:
550 divided by 57 is 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 6891.859
Subtract 513 from 550 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to 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: 6891.8596
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.

Moving on to step 11:
If we divide 280 by 57, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 6891.85964
If we subtract 228 from 280, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
If we divide 520 by 57, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 6891.859649
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.

Let's proceed to step 13:
If we divide 70 by 57, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 6891.8596491
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.

Advancing to step 14:
57 can be fit into 130 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 6891.85964912
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 6891.85964912, with a leftover of 1.6e-08.
