We're dividing 395965 by 57 
The aim is to understand the frequency of 57 in 395965.

On to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 57

Step 2:
If we divide 39 by 57, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 57

Going ahead to step 3:
395 divided by 57 is 6 with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 342 from 395 to get 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 57

Advancing to step 4:
57 can be fit into 539 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 513 from 539 leaves us with 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 57

Moving on to step 5:
266 divided by 57 is 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 694.0
Deduct 228 from 266 and we're left with 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 57

Advancing to step 6:
57 goes into 385 6 times with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 6946.0
Subtracting 342 from 385 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.

On to step 7:
If we divide 430 by 57, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 6946.7
Subtracting 399 from 430 leaves us 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:
57 can be fit into 310 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6946.75
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 57, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 6946.754
If we subtract 228 from 250, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
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: 6946.7543
Subtracting 171 from 220 leaves us 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.

Going ahead to step 11:
490 divided by 57 is 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 6946.75438
If we take 456 away from 490, we end up 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 12:
When dividing 340 by 57, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 6946.754385
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.

Advancing to step 13:
57 goes into 550 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 6946.7543859
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.

Going ahead to step 14:
57 can be fit into 370 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 6946.75438596
Subtract 342 from 370 to get 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 quotient of the division is 6946.75438596, and the remainder is 2.8e-08.
