946241 ÷ 57 
The aim is to understand the frequency of 57 in 946241.

Step 1:
If we divide 9 by 57, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 57

Step 2:
57 goes into 94 1 times with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 57 from 94 leaves us with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 57

Let's proceed to step 3:
When dividing 376 by 57, we get 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 34 after subtracting 342 from 376.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 57

Going ahead to step 4:
If we divide 342 by 57, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 166.0
If we subtract 342 from 342, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 57

Step 5:
When dividing 4 by 57, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 1660.0
If we subtract 0 from 4, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 57

Step 6:
57 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 16600.0
The remainder is 41 after subtracting 0 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
57 goes into 410 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 16600.7
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
110 divided by 57 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 16600.71
Deduct 57 from 110 and we're left 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 9:
When dividing 530 by 57, we get 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 16600.719
The remainder is 17 after subtracting 513 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
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: 16600.7192
Deduct 114 from 170 and we're left 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.

Let's proceed to step 11:
When dividing 560 by 57, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 16600.71929
Subtract 513 from 560 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
57 goes into 470 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 16600.719298
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.

Moving on to step 13:
The number 57 fits into 140 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 16600.7192982
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.

Going ahead to step 14:
57 can be fit into 260 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 16600.71929824
If we take 228 away from 260, we end up 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.

The final outcome is 16600.71929824, with a leftover of 3.2e-08.
