Let's divide 268645 by 57
The aim is to understand the frequency of 57 in 268645.

Let's proceed to step 1:
The number 57 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 57

On to step 2:
If we divide 26 by 57, we get 0 and a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 57

On to step 3:
268 divided by 57 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 228 from 268, we get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 57

Advancing to step 4:
57 can be fit into 406 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
The remainder is 7 after subtracting 399 from 406.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 57

Going ahead to step 5:
57 can be fit into 74 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 471.0
If we subtract 57 from 74, we get 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 57

Moving on to step 6:
When dividing 175 by 57, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 4713.0
Deduct 171 from 175 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
57 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4713.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
57 goes into 400 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 4713.07
Deduct 399 from 400 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
57 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4713.07
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 57, we get 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 4713.0701
If we take 57 away from 100, we end up with 43.
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 11:
57 goes into 430 7 times with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 4713.07017
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.

On to step 12:
When dividing 310 by 57, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4713.070175
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.

Step 13:
If we divide 250 by 57, we get 4 and a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 4713.0701754
If we take 228 away from 250, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
57 goes into 220 3 times with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 4713.07017543
Deduct 171 from 220 and we're left 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.

The final outcome is 4713.07017543, with a leftover of 4.9e-08.
