We're dividing 391384 by 57 
The aim is to understand the frequency of 57 in 391384.

Let's proceed to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 57

Let's proceed to step 2:
57 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 57

Going ahead to step 3:
If we divide 391 by 57, we get 6 and a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 342 from 391 and we're left with 49.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 57

Advancing to step 4:
57 can be fit into 493 8 times, resulting in a remainder of 37.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 37 after subtracting 456 from 493.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 57

Step 5:
The number 57 fits into 378 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 686.0
Subtract 342 from 378 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 57

Advancing to step 6:
57 can be fit into 364 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 6866.0
Deduct 342 from 364 and we're left 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.

Advancing to step 7:
When dividing 220 by 57, we get 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 6866.3
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.

Moving on to step 8:
490 divided by 57 is 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 6866.38
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.

Going ahead to step 9:
When dividing 340 by 57, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 6866.385
Deduct 285 from 340 and we're left 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.

Advancing to step 10:
When dividing 550 by 57, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 6866.3859
Subtracting 513 from 550 leaves us 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 11:
The number 57 fits into 370 6 times, leaving a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 6866.38596
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.

Let's proceed to step 12:
57 can be fit into 280 4 times, resulting in a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 6866.385964
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
When dividing 520 by 57, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 6866.3859649
The remainder is 7 after subtracting 513 from 520.
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 14:
70 divided by 57 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 6866.38596491
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.

The quotient of the division is 6866.38596491, and the remainder is 1.3e-08.
