Let's divide 872425 by 57
The aim is to understand the frequency of 57 in 872425.

Step 1:
If we divide 8 by 57, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 57

Step 2:
If we divide 87 by 57, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 87, we get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 57

Going ahead to step 3:
57 goes into 302 5 times with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 285 away from 302, we end up with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 57

Let's proceed to step 4:
174 divided by 57 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
The remainder is 3 after subtracting 171 from 174.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 57

On to step 5:
The number 57 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 1530.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 57

Going ahead to step 6:
If we divide 325 by 57, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 15305.0
Deduct 285 from 325 and we're left with 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 7:
57 goes into 400 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 15305.7
If we take 399 away from 400, we end up 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.

Moving on to step 8:
57 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15305.7
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
57 goes into 100 1 times with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 15305.701
If we subtract 57 from 100, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
When dividing 430 by 57, we get 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 15305.7017
If we subtract 399 from 430, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
If we divide 310 by 57, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 15305.70175
If we take 285 away from 310, we end up 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.

On to step 12:
If we divide 250 by 57, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 15305.701754
The remainder is 22 after subtracting 228 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
220 divided by 57 is 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 15305.7017543
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 14:
The number 57 fits into 490 8 times, leaving a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 15305.70175438
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.

Our division results in 15305.70175438 with a remaining 3.4e-08.
