407251 divided by 57 
The aim is to understand the frequency of 57 in 407251.

Moving on to step 1:
If we divide 4 by 57, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 57

Advancing to step 2:
57 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 57

Let's proceed to step 3:
If we divide 407 by 57, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 399 away from 407, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 57

Step 4:
If we divide 82 by 57, we get 1 and a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtract 57 from 82 to get 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 57

Advancing to step 5:
The number 57 fits into 255 4 times, leaving a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 714.0
Deduct 228 from 255 and we're left with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 57

Let's proceed to step 6:
If we divide 271 by 57, we get 4 and a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 7144.0
The remainder is 43 after subtracting 228 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
The number 57 fits into 430 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 7144.7
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.

Let's proceed to step 8:
If we divide 310 by 57, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 7144.75
Subtracting 285 from 310 leaves us with 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:
57 goes into 250 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 7144.754
The remainder is 22 after subtracting 228 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 57, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 7144.7543
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.

On to step 11:
490 divided by 57 is 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 7144.75438
Deduct 456 from 490 and we're left 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:
When dividing 340 by 57, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 7144.754385
If we subtract 285 from 340, we 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:
550 divided by 57 is 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 7144.7543859
Deduct 513 from 550 and we're left 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.

Advancing to step 14:
The number 57 fits into 370 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 7144.75438596
If we subtract 342 from 370, we 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 final result is 7144.75438596 with a remainder of 2.8e-08.
