278496 divided by 57 
The aim is to understand the frequency of 57 in 278496.

On to step 1:
If we divide 2 by 57, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 57

Moving on to step 2:
57 goes into 27 0 times with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 57

Step 3:
The number 57 fits into 278 4 times, leaving a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 228 from 278 to get 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 57

Advancing to step 4:
57 goes into 504 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 456 from 504, we get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 57

Advancing to step 5:
When dividing 489 by 57, we get 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 488.0
If we subtract 456 from 489, we get 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 57

Step 6:
57 can be fit into 336 5 times, resulting in a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 4885.0
If we take 285 away from 336, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 4885.8
If we take 456 away from 510, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 57 fits into 540 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 4885.89
If we take 513 away from 540, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
If we divide 270 by 57, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 4885.894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
420 divided by 57 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 4885.8947
The remainder is 21 after subtracting 399 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
When dividing 210 by 57, we get 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 4885.89473
Deduct 171 from 210 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
If we divide 390 by 57, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 4885.894736
Deduct 342 from 390 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
57 goes into 480 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 4885.8947368
Subtract 456 from 480 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
57 goes into 240 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4885.89473684
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 4885.89473684, and the remainder is 1.2e-08.
