We divide 398002 by 57
The aim is to understand the frequency of 57 in 398002.

Step 1:
3 divided by 57 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 57

Moving on to step 2:
57 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 57

Going ahead to step 3:
398 divided by 57 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 342 from 398, we get 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 57

Let's proceed to step 4:
The number 57 fits into 560 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 513 from 560 leaves us with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 57

On to step 5:
If we divide 470 by 57, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 698.0
If we subtract 456 from 470, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 57

Step 6:
The number 57 fits into 142 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 6982.0
If we subtract 114 from 142, 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.

On to step 7:
If we divide 280 by 57, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 6982.4
Deduct 228 from 280 and we're left 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.

Advancing to step 8:
The number 57 fits into 520 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 6982.49
Deduct 513 from 520 and we're left with 7.
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 9:
70 divided by 57 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 6982.491
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
If we divide 130 by 57, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 6982.4912
Subtracting 114 from 130 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 57, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 6982.49122
Subtract 114 from 160 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 6982.49122 with a balance of 4.6e-05.
