Let's divide 945398 by 57
The aim is to understand the frequency of 57 in 945398.

Step 1:
If we divide 9 by 57, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 57

Going ahead to step 2:
94 divided by 57 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 57 from 94 to get 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 57

Let's proceed to step 3:
375 divided by 57 is 6 with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 342 from 375 to get 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 57

Moving on to step 4:
When dividing 333 by 57, we get 5 with a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 165.0
Deduct 285 from 333 and we're left with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 57

Step 5:
If we divide 489 by 57, we get 8 and a remainder of 33.
The next digit of our result is 8. 
Result so far: 1658.0
Subtract 456 from 489 to get 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 57

Advancing to step 6:
57 can be fit into 338 5 times, resulting in a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 16585.0
Subtracting 285 from 338 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
When dividing 530 by 57, we get 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 16585.9
If we take 513 away from 530, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
When dividing 170 by 57, we get 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 16585.92
If we take 114 away from 170, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
560 divided by 57 is 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 16585.929
Subtracting 513 from 560 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
57 can be fit into 470 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 16585.9298
If we take 456 away from 470, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
57 can be fit into 140 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 16585.92982
Subtract 114 from 140 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
The number 57 fits into 260 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 16585.929824
Subtracting 228 from 260 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
320 divided by 57 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 16585.9298245
Deduct 285 from 320 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
The number 57 fits into 350 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 16585.92982456
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 16585.92982456, with a leftover of 8e-09.
