We divide 397429 by 57
The aim is to understand the frequency of 57 in 397429.

Moving on to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 57

Step 2:
39 divided by 57 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 57

Let's proceed to step 3:
When dividing 397 by 57, we get 6 with a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 342 from 397 to get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 57

On to step 4:
57 can be fit into 554 9 times, resulting in a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 513 from 554 and we're left with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 57

Going ahead to step 5:
If we divide 412 by 57, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 697.0
If we take 399 away from 412, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 57

Going ahead to step 6:
139 divided by 57 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 6972.0
Deduct 114 from 139 and we're left 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 7:
250 divided by 57 is 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 6972.4
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.

Let's proceed to step 8:
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: 6972.43
If we subtract 171 from 220, 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.

Let's proceed to step 9:
57 goes into 490 8 times with a remainder of 34.
The next digit of our result is 8. 
Result so far: 6972.438
The remainder is 34 after subtracting 456 from 490.
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 10:
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: 6972.4385
If we take 285 away from 340, we end up 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.

Step 11:
If we divide 550 by 57, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 6972.43859
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 12:
57 can be fit into 370 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 6972.438596
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.

Going ahead to step 13:
280 divided by 57 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 6972.4385964
Subtracting 228 from 280 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
If we divide 520 by 57, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 6972.43859649
Subtract 513 from 520 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 6972.43859649, and the remainder is 7e-09.
